Napkin Chess
Coins come in three sizes: 2, 3, or 4, which are worth 2, 3, and 4 points. The pulldowns under "total numbers" control how many of each are available.
Object: two players alternate dropping a coin of size 2, 3, or 4 without overlapping any coins already dropped. The player with the most points wins.
A move consists of two parts:
1. A player clicks "size 2," "size 3," or "size 4," which drops a coin at the lower-left corner.
2. The player drags the newly created coin from the lower-left corner to a good place.
A coin is well placed when it does not overlap an edge of the board or a previously placed coin. Also, if "hole in napkin" is checked, a coin may not overlap the small black disk close to the center.
The warning sign "overlap!" shows when the coin is not well placed. When the coin is well placed, the next player can move.
The first coin of the first player should be of size 2 (this is not enforced by the program).
