Katarenga is a two-player abstract consisting of a variable board, 16 pawns, and rules of movement derived from Chess. Each pawn’s move is governed by the colour of the square it moves away from (red = rook, yellow = bishop, green = knight, blue = king). For each game the board is constructed from four double-sided quarterboards, each of which can be placed either way up and any way round, yielding a total of over 24,000 different 8×8 boards. In the basic game your aim is to get two of your pawns to the opposite side without being captured. The same equipment can be used for playing a variety of other games with the same rules of movement and capture. Can you invent more?
