Koban Shiai

This is a variant of the game Nim that I learned a long time ago.  It's a 2 player strategy game on the same screen.

Rules:

Players take turns removing coins from the board, but you can only remove coins from a single row at a time, and must only remove 1, 2, or 3 coins each turn.   The player who takes the last coin LOSES.

Click the buttons on screen to choose your coins, and learn a little Japanese while you do it.  Don't worry, the tooltips and menus are in English
