I just want to start off by saying, the majority of the content I will be posting are not mine! I will be using other sources that are not mine, I am just bring this strictly as a GUIDE! So now that simple little disclaimer is announced, let's get to the guide!

League of Legends is a fast-paced, competitive online game that blends the speed and intensity of an RTS with RPG elements. Two teams of powerful champions, each with a unique design and playstyle, battle head-to-head across multiple battlefields and game modes. With an ever-expanding roster of champions, frequent updates and a thriving tournament scene, League of Legends offers endless replayability for players of every skill level.

Overall League of Legends is a multiplayer online battle arena (MOBA) genre video game developed by Riot Games. It was designed to operate on the Microsoft Windows operating system when it was first launched on October 7th, 2008 and released a year later on October 27th, 2009. The game was in beta from April 10th, 2009 to October 26th, 2009.

Two main protagonists for the popular Warcraft III mod, Defense of the Ancients: Allstars (commonly abbreviated as DotA), Steve "Guinsoo" Feak and Steve "Pendragon" Mescon are involved with Riot Games in the process of making of League of Legends. Guinsoo created DotA: Allstars from the original DotA, created by Eul, by adding his own mix of content, including over 40 heroes, numerous items, and various gameplay changes. Guinsoo then passed DotA: Allstars on to its current developer, Icefrog. Pendragon, who is the Director of Community Relations for Riot Games, helped create the DotA: Allstars website along with its forums, and is still currently working on DotA: Allstars alongside League of Legends. The core game is free to play, and new users can register an account here.

Now the game itself is on average 30-40 minutes, but can be as short as 20 (if your surrender to your opponent in a team vote) or as long as 60 minutes or more, depending on how good each team is. Now the game selects five members per team and each side choose their champion depending on the role that is selected, then the game will began. After a short load time, each team will spawn on two different sides of the map, a red side and blue side. Your main objective is to battle your opponent and get to their nexus before the enemy team does. During that time you can kill your opponent, take objectives (Towers, Dragon, Rift Herald, and Baron), Kill jungle monsters, and Buy Items that makes your champion stronger! No matter if you witness Victory or Defeat, always be positive and say "Good game!" to your opponent.

Here is a video on "What is League of Legends," by Riot Games! Play Video

Assassin

Agile champions that close in and take out unsuspecting targets in the blink of an eye. However, they must pick their opportunities carefully since a high-octane offense comes at the cost of low defense and long waits between takedown attempts.

Fighter

Versatile champions that can take on the role of damage dealer or defender of more fragile teammates. They occupy a happy medium between the massive damage of a Marksman or Mage and the prolonged survivability of a Tank that lets them adapt to various situations.

Mage

Volatile champions that cast high-impact spells with various effects, which can include damage, healing, stuns, and more. They are fragile, however, so accuracy and timing are often key to keeping themselves, and teammates, alive.

Marksman

These champions deal large amounts of consistent, rapid-fire damage to enemies from a safe distance. They often employ the help of Supports to stay alive, as they are fragile and require time to build up their attack strength over the course of a game.

Support

These champions provide lots of utility and set up teams to succeed with practical skills, such as heals, shields, stuns, and more. They often set the stage to lay traps and avoid ambushes, and depend on teammates to deal the majority of the damage.

Tank

Robust champions that can withstand the front lines of conflict, but often don't do much damage themselves. They focus on starting fights, taking hits, and drawing attention away from the fragile damage-dealers on the team, who can finish off the preoccupied enemies.

Out of the six different roles you can play, not every champion is stuck to one role! You are free to experiment and choose from different playstyles, how you want to play your champion! You can play them AP (Ablity Power), which does Magic damage to enimes and monsters. You can play them AD (Attack Damage), which does Phisical Damage to enimes and monsters. You can even go full tank, to with stand enimes damage, and anything else out there that may hurt you! You have so many playstyles and champions to choose from, the game replayablity is what makes it apeal to most gamers and keeps them interested. So, dont feel restricted to playing a champion in 1 specific role, do what you feel is strong and helps you win games!

Now look here guys, and gals! Out of everything in League of Legends, the Summoner's Code, is the main rule code every summenor, which is YOU, has to follow! It is very important that you listen to everything it has to tell you cause if you break the rules you can, and will be punished. It is mandatory that you read the rules or it could cause your account to result in a restriction, or a ban! Riot Games takes the rules very seriously and will not put up with people who can't follow the rules.

THE SUMMONER'S CODE!

Support Your Team

"[Teamwork] is the fuel that allows common people to attain uncommon results." -Andrew Carnegie

While we all carry a diverse set of individual ambitions and expectations into a game of League of Legends, once we hit the Field we're a part of a team. For better or worse, our fates are intertwined with that of our teammates. Once the game gets into full swing, you have to make a choice between being a positive force for your team, or contributing to your own demise.
Being a good team player begins at champion select. Be open minded when considering the needs of your team. If you're the last one to pick, try to fill a niche in your team that hasn't already been filled. If everyone's picked and something stands out as a deficiency in your team composition, try asking for another player to fill the gap, or change roles to embrace that responsibility yourself. Remember, that by taking on a role you don't normally play, you'll learn more about unfamiliar champions and increase your own skill level.
Once you get in game, try to keep an open line of communication. Warn your teammates if someone is missing from your lane, or if something is placing them in immediate danger. If they're not paying attention to chat you can always try pinging the map. Just remember that one ping is enough! Also, remember that you have to be there to contribute, so don't leave the game or go AFK! Encourage players who are having trouble, and congratulate those who are playing well. And most of all, if you're having a bad game don't take it out on your team!

Drive Constructive Feedback

"When you confront a problem you begin to solve it." -Rudy Giuliani

Player feedback is an important force in the decision making process of Riot Games. If you want to make your voice heard, taking the time to let us know how you're feeling about the game is a good place to start. When you give feedback, make sure you take a holistic approach. If you only give negative feedback, you may find that the changes you influence detract from what you initially enjoyed. Moreover, people are simply more likely to listen if you present yourself in a calm, well thought out manner.
That being said, don't be afraid to tell us if you feel strongly, and why. Try to be straightforward, specific, and always try to make your feedback direct and concise. For instance, saying something along the lines of:
"I used to love playing Katarina because her skills give her high mobility in lane, but with the latest nerfs to Death Lotus, I no longer feel like I have a strong enough presence in team fights to be viable. I don't think that I'm going to be playing Kat in the future unless she undergoes some revisions."
Is a much better way of expressing your dismay at a patch than beginning with an irate tirade, then asking for changes to be reverted or attempting to force an alternate solution. Remember that we're listening and making changes every couple of weeks, so, with a little patience, you may find that your issues will work themselves out.

Facilitate Civil Discussion

"To disagree, one doesn't have to be disagreeable." -Barry Goldwater

As we mentioned earlier, we want you to give feedback, but being part of the community doesn't stop there. Whether you're in chat, in a game, or on the forums, there are plenty of people to meet, and plenty of topics to discuss. Whether you're discussing game balance and champion viability, trying to form a premade team, or just want to express your affection for the legendary and infamous Gentleman Cho'gath, we encourage you to share your thoughts with other players.
When you choose to participate in a discussion with the rest of the playerbase, always try to be receptive to another player's point of view. If you keep an open mind, you'd be surprised what valuable information you can glean from your fellow players. Also, be mindful of how you present your point of view. If a player feels strongly on a subject, don't get caught up trying to have the last word. Just state your side and exit the conversation gracefully rather than give them the opportunity to pick a fight.

Enjoy Yourself, but not at Anyone Else's Expense

"Short is the joy that guilty pleasure brings." -Euripides

Making games is our business, so it should come as no surprise that we want you to have a lot of fun. We want you to get excited, to have tension-filled moments, and to celebrate your success. This doesn't mean that we're okay with you ruining anybody else's day.
Remember, taking a jab at your friend in the middle of the game is a lot different than making a glib remark at a complete stranger. Someone who is unfamiliar with what you consider playful may take your comment as an attack and react unfavorably. If two players on a team start fighting, good communication and teamwork become nearly impossible. Once communication breaks down, the likelihood of victory is drastically diminished. It isn't uncommon for simple, good natured teasing to spiral out of control into a loss, so do yourself a favor and don't run the risk of sabotaging your own success.

Build Relationships

"No man is an island..." -John Donne

League of Legends is a team game, and, as such, familiarity and rapport with the other competitors with whom you play is going to be a big part of your success. With that in mind, it would behoove you to adopt a cordial demeanor and attempt to make friends. If you have fun playing with another player, make use of the end of game lobby to thank that player for the game and send a friend request. The more friendly players that you have at your disposal, the better your chances are of getting a good, friendly game.
Use the tools at your disposal to try and build a circle of other players of a similar skill level. If you have a relationship with a group of players that you trust, you are much more likely to get good feedback on how you're playing, receive support when learning a new champion, and just have a good time overall.

Show Humility in Victory, and Grace in Defeat

"To be humble to superiors is duty, to equals is courtesy, to inferiors is nobility." -Benjamin Franklin

Having a great game is one of the biggest joys that League of Legends can bring you. But always bear in mind that when you're relishing that landslide victory there is someone on the receiving end that is probably ripping their hair out. While it's alright to celebrate, make sure that you keep any gloating (or any other mode of self-indulgence) out of all chat. Instead, thank your opponents for the game. After all, despite their best efforts, they just made you a very happy person.
Moreover, if you've just lost, avoid pointing any fingers or deploying excuses. Even if you had a great game, it's not alright to blame your team. You had five opponents in that game, and - seeing as you just lost - chances are that they had something to do with it. We all know that losing can be frustrating, particularly if it's a close game or one that's completely one sided, but nobody likes a sore loser. Instead, thank your opponents for the game, and take a moment at the end of game screen to ask what you could have done better. If you're polite, you might pick up a few pointers that can help you counter your opponent's strategy in the future.

Be Resolute, not Indignant

"It is easier to find men who will volunteer to die, than to find those who are willing to endure pain with patience." -Julius Caesar

Intrinsic to the idea of competition is the notion that, when our pride is on the line, emotions tend to run high. Every person that we encounter is going to carry a different set of circumstances with them into the game, and therefore is going to have a different level of tolerance for frustration. If you end up in a game with an abusive player, don't lower yourself to their level. Instead, politely ask them to calm down.And remember, even if you're having a bad game, quitting or going AFK just ruins the game for the rest of the players. If someone's really starting to bother you, the mute and ignore commands are always there to resolve the situation.
And remember, while nobody likes being insulted, it pays to take a moment to consider the circumstances. Remember that this is a competitive game, and, more often than not, the other player is just venting their frustration. Try not to take it personally. Everyone has a breaking point and everyone rages sometimes. At some point you may find yourself in the other person's shoes.

Leave No Newbie Behind!

"Be an opener of doors for such as come after thee." -Ralph Waldo Emerson

We all started somewhere, and if we're going to do justice to the people who helped us move up the ladder, we have to start by paying homage to our roots. If you see a player having a bad game, or who clearly doesn't grasp the fundamentals of the genre, try offering some constructive advice. If you do so in a civil and friendly manner, it's likely that they will be receptive. Oftentimes they'll be downright grateful that somebody took the time to let them know how to improve instead of yelling at them.
Never get frustrated by an inexperienced player's performance. At some point, you were just as green as they were, even if it was the day that you downloaded the League of Legends client. Have a little patience, and try and help the player step up to a level where both of you can enjoy the game. At the same time, don't be discouraged if they aren't receptive. Some small percentage of players will get hung up on the notion that they don't need anybody's help, and, no matter how politely you try to lend a hand, they won't want to hear it. That's no reason to give up on the rest of them!

Lead by Example

"Leadership is practiced not so much in words as in attitude and in actions." -Harold S. Geneen

If you share our vision of a game where players exercise good sportsmanship, help each other improve and form lasting friendships, you've got to start living the dream before anybody else is willing to do so. It's all well and good to say you're on board for the revolution, but if you don't first make yourself a paragon of model behavior, no one is going to be fooled. Nobody's asking you to be perfect, but we do want you to, whenever possible, strive to uphold the same standards of behavior that you expect everyone else to maintain.

So, remember! Stay positive, remain calm, and keep to the code!

When you first start on the rift, you must play Bot games. These games are here to introduce you to the game and help you learn the basics. You get to play with a select number of champions that you get a level 1. These are, Ashe , Garen , Jinx , Kha'Zix , Lissandra , Lux , Ryze , Shyvana , Varus , and Wukong . These are the basic champions that you play to find a play style that suits you!
Each champion type, has a role that is general for that champion playstyle. Tanks are usually in the top lane, Mages are middle lane, Marksman and Support in the bottom lane, and assassins, go either middle lane or the jungle. The jungle is available to anyone, but a jungler role is unlocked when you earn the smite summoner spell. This allows you to start in the jungle level 1 and fight jungle monsters. You will learn how to do this the more you play and learn from researching on the internet. But, like I said before, feel free to experiment on what role, lane and build you like to go with.

When you reach level 6 a whole new experience opens up to the user and you are able to join other players and play a 5v5 battle, 3v3 battle, or any special game modes that are available at the time. Hitting this significant milestone means you’ve officially mastered the basics of the game. You’ll be hitting level 30 in no time! Until then, let’s go over some changes to your experience and a couple tips on how to tailor the game for you.

Free to play champion rotation!

Champions cost, so until you start earning currency in-game, you get to use the free to play champions! The pool of Champions you’ve been playing is just a taste of the large and diverse League of Legends roster. Since you’ve hit level 6, you now have the opportunity to explore them all, starting with the Free-to-Play rotation! The Free-to-Play rotation is a set of 10 champions temporarily unlocked for every player, which will replace the starting champion pool you’ve been using. The champions in the rotation represent a range of roles, playstyles, and complexity, so you can find the one that fits you best. The rotation changes every week, so try them all out before they swap out!

Game modes!

There are many game modes that unlock for you after hitting level 6. You are able to still play bot games if you do not feel comfortable yet playing against other players, but if your up for the challenge then you can try the others out.

First, Summoners Rift, it's a 5v5 map where 2 teams are randomly selected and play against each other to try and win the game. Within that game mode you can play Normal games, these are the original format of LOL, you can play solo, or join with friends and play together against others. Then there is Team Builder, this is a mode where you select your role and champion before entering a game, and select the members you want on your team. Once you acquire 16 champions then you can play Draft mode, it is a Pick and Ban phase team select where each team is able to chose what champions they don't want in the game, and the champions they do want.

Then, you have the Twisted Treeline, and it's a 3v3 map, and has the same game modes as Summoners Rift, just on a smaller map and a shorter game. It has 2 lanes and a small jungle with Buff-granting Alters.

Next, is the Howling Abyss where its a 5v5 one laned map, and all champions are randomly selected on both teams. You are then able to trade champions with other players on your team and re-roll for a different champion, if you're feeling lucky. You also get increased stats, leveling, and start with 3 skill points.

Last, are the specialty game modes, that Riot Games releases every year. In these the rules are different and are there to have fun and play with your friends. They are available randomly throughout the year and are available for anyone to play! There are fun game modes like U.R.F where all champions get super increased stats, and causes for crazy mayhem and crazy build paths.

All of these game modes are so much fun to play, and your objective is to have fun, while also trying your best to beat your opponent at the game!

Future Milestones

During playing the game, you will start to earn Mastery points, summoner spells, and currency. You can use these to make it easier for you on the rift and other game modes. Once you reach level 10, you receive all the summoner spells, and when you hit level 30, you receive all the mastery points. You unlock one mastery point and one rune slot for every level you gain. Runes and Masteries let you customize your champion’s playstyle.

Level 30 is the max rank you achieve playing. When you get here you can then start playing ranked games. This is for high level play, against other players. This is the place where you make a name for yourself and help to improve on your play so that maybe one day you can become a pro-player. Now you don't have to play ranked if you don't want to but it is where you go if you're looking to get serious. League system is a ranking system to find other players of a similar skill level to play with or against. In seasons one and two, the system used a single ladder with ranking determined by Elo rating system. Since season three, the system uses six tiers with five divisions per tier, where ladder rankings within a league are determined by League Points (LP) and hidden Matchmaking Rating (MMR). In season 4, a new tier between Challenger and Diamond I has been added: the Master tier.

League Points

Each ranked game you win earns you League Points while each lost one decreases your current LP. The exact amount of lost or earned League Points per game depends on your hidden Match Making Rating. If you have higher MMR than a set amount for your division you gain more LP per won game and lose less LP per lost game, if your MMR is lower you gain less and lose more LP per game.


League Points inactivity decay

There is no League Points inactivity decay for players Bronze, Silver and Gold Tiers.

For players in Platinum, Diamond, Master & Challenger Tiers there is League Points inactivity decay over time - if you haven't played ranked in 28 days or 10 days if you are in the Master or the Challenger Tier. It decays per the set amount every 7 days afterwards until you play a ranked game. The amount of LP that you lose per decay period depends on the tier that you're in:

Bronze - 0
Silver - 0
Gold - 0
Platinum - 35
Diamond - 50
Master & Challenger - 250

Notes:
While you're inactive, you're hidden from the ladder view for everyone except yourself.

Match Making Rating doesn't decay when LP decay occurs.

Promotions Series will end after 28 days (even if you play games within 28 days)

Tiers and Divisions

Each tier (except Challenger and Master) contains five divisions, each division is numbered using roman numerals in a descending order from V(5) to I(1), with V being the lowest and I being the highest.

Tiers from the lowest to highest:

Unranked (Provisionals)
Bronze
Silver
Gold
Platinum
Diamond
Master
Challenger

Divisions from the lowest to highest:

V
IV
III
II
I
