War of Kingdoms, an invented card game. (press the link to see a description of the game).

The game is generously hosted by:


Doomka - Reversed checkers. Claimed to be invented by many people. Rules are basically the same as in checkers but whoever loses is the winner.


Checkers Twist (TM)- Invented by by I.A. and E. Yechiam. This is checkers where each pawn can make either one move or two moves. If a kill is made on the first move then the second move option is abolished. A kill can take place in the second move.
