Custom game

Custom Games are games for 10% reduced experience which allow you to test new Champion builds against players and/or bots.

Bot Order and Laning in Custom Games
Contrary to popular belief, it is possible to control which bot goes to which lane during the custom game set-up process. When adding bots to your custom game, disregarding any humans players on either team, the bots will go to a lane as follows:

1st and 4th bots go bottom, 2nd and 5th bots go top, and 3rd bot goes mid.*

Again, when sorting this, completely disregard any human players. A player can be in any position on the team, the game will simply work from the top down, assigning a lane to each bot (hence why when you play a solo-player 5v5 custom, the lane spot left open for you will always be at top lane, since there's not a 5th bot to take that position).

EDIT: As of the Jayce Patch on Fri, 2012-07-06, bots now adapt to player lane choices. Let's say you go mid. The bots will parse this and take thier places at top and bottom lane.

Hardcore PVP

 * This mode is rumored to be (as the tittle states) a hardcore PVP situation, in whitch you farm no minions or Jungle mobs, but instead fight to the death.

Protect the Bot

 * Game variant where all normal game rules apply, but the goal of the game is to kill, (in any way), the enemy Soraka Bot until she has died 10 times. No spells or items are prohibited, everything is fair game in this game variant. This game type is also known as "Protect the Queen."

Catch the

 * This game mode has a time limit of 10 minutes in which the attacking team (the team without the Teemo) must kill the Teemo 2 times while the Defending (the team with the Teemo) must protect him for 10 minutes. While the Teemo cannot leave the jungle, must keep moving to stop his passive from activating, cannot run through mid lane, cannot run in between the towers, and cannot run back or recall, everyone else can.
 * To Catch The Teemo

Catch the Yeti

 * Limit of 10 kills against the enemy's . The objective of "Catch the Yeti" is to kill the other team's Nunu while also defending your own Nunu. The first team to kill the opposing Nunu 10 times (or 5 for a much shorter game) wins. There is no experience gained from minions, including jungle creeps. This means that Nunu is unable to use his Consume, and is therefore very limited in terms of abilities. Nunu cannot return to base without giving the enemy a point.(In short it's the same rules as catch the teemo)
