Ranked: Ranked in League of Legends is the same as Twisted Treeline and Summoner's Rift. Except with the exception for, Summoner's Rift ranked is either solo queue, duo queue, or full team queue. Twisted Treeline Ranked you must have a full team of three. In order to compete in ranked matches you must be level 30, in a ranked team, and be able to handle a lot of annoying people. Ranked is by far the most... Criticizing of the game modes. I have personally never played a ranked game at all and don't really plan to.
Here is a guid to "not suck" at solo queue ranked.

For videos and pictures its pretty much the same as summoner's rift and twisted Treeline except for the fact you rise or lower in ELO (the points you recieve for playing ranked)
That's it for ranked and Classic aka PvP. Now for the fun part of this game, Bots.
Until next time, stay nerdy!~
