Rule Variations
Overview
As of v1.2.0, Checkers allows games to be played with different rule variations. The following rules are supported (and more may be added in future):
| Variation | Board Size | Notes |
|---|---|---|
| English Draughts (aka American Checkers) | 8 | You must jump if a jump is available. Men may only move and capture forward. Kings may move and capture forwards or backwards. No flying kings. |
| English Draughts, no forced jumps | 8 | Same as English Draughts but you may choose not to jump if a jump is available. |
| Brazilian Checkers | 8 | Same rules as International Draughts but on a 8x8 board. |
| International Draughts | 10 | You must jump if a jump is available. Men may only move forward but may capture backward. Flying kings; kings may capture at any distance along a diagonal and land any distance behind the captured piece. |
| Canadian Checkers | 12 | Same as International Draughts but on a 12x12 board. |
You can use the Rules control panel button on any board to select which rules you want to play under. Right-click the button to cycle through the available rules, and left-click the button to receive a rules summary. You can only change the rules for a game either before the game is created or during the game setup phase (before inviting a second player).
Each particular rule set is of course only available on a board of the appropriate size. E.g. an 8x8 board will allow the English Draughts (with and without forced jumps) and Brazilian Checkers variations, but not any others. To create a board of a given size, use the -size option, e.g.
/chc create board board1 -size 10
The default size is 8. Valid sizes are 8, 10 and 12.
Note: most rule sets specify that the longest sequence of jumps must be taken by the player. Checkers does not currently enforce this restriction, although this may be added in future.
