CHESS LADDER RULES:

Chess Ladder Rules:

Chess Ladder is a form of competition where each player is assigned a position (rank). A lower number means higher rank on the ladder (better position).
The goal of the competition is to move up the Ladder, ultimately to the number 1 position (highest rank).
To start a Ladder game, access the Ladder table via the link above and then click "Play!" next to the player you'd like to challenge.
After each Ladder game has ended, both players are assigned new positions on the Ladder, depending on their current positions, and the result of the game:
1. If the winning player has a lower rank than the losing player, they are moved up half the distance between their position and the losing player's position. The losing player is moved one position down. (For example, if the winning player was 10th and the losing player was 4th on the ladder, their new positions will be 7th ((10+4)/2) and 5th (4+1) after the game)
2. If the winning player is directly below the losing player, their positions are swapped. (i.e. the winning player is moved one position up, and the losing player — one position down)
3. If the winning player has the higher position, they are moved one position up and the losing player is moved one position down.
4. In case of a draw, the player with the lower position is moved up by one and the other player keeps their current position. If the players are next to each other in the ladder, their positions remain unchanged.
5. If one of the opponents is no longer participating in the Ladder at the time game ends, the other player is moved one position up in case of a win or one position down in case of a loss (position remains unchanged in case of a draw).
When joining a Ladder, the player is placed at the last position (i.e. lowest rank).
Players can only challenge other players on the Ladder if their positions are within 1/10th of the total Ladder ranks. (For example, if there are currently 730 players in the Ladder, you can only challenge players within 73 positions above/below your own)
Ladder challenges cannot be declined, and Ladder games cannot be cancelled.
When challenging another player to a Ladder game, the player who started the game will play Black, the defending player will play White.
Players are automatically removed from the Ladder if they time out in 3 Ladder games within one month (to avoid further losses since Ladder challenges cannot be declined).
Players can lose their rank (i.e. move down the Ladder) without finishing any games, due to other players moving up the ladder after winning their games, which will effectively "pushes" other players down the Ladder.
If you retire from the Ladder, you will need to finish all your currently active Ladder games, before you are able to re-join the Ladder.
