Cross Numbers Game

Volume IV in one of the Russell little books card game sets. The game features a deck of cards split into four colored triangles with different numbers on them. The goal is to score enough points to win the game, and play your cards to end the round. On their turn players match the colored sides of the cards so that the numbers add to a multiple of 5 to score points, while matching multiple sides can give a bonus as in other domino-style games like Contack.
