Chamäleon

The game has a board of a grid of 4 colours, large wooden tiles in the colours, a set of stickers to go on the tiles divided into 4 sections showing 3 bugs and a chameleon on coloured backgrounds. And 4 long wooden sticks, 36cm square cut wooden sticks.
The game is essentially a chess game for four players. The tiles change their "roles" depending on the color of the square they are on. As the game moves on, the playing field is reduced in size by the wooden sticks, until it is a minimum of 3x3 squares big. This prevents drawn out final duels.
