13. The two snakes
Using the CodyRoby cards, two snakes move around the board trying to obstruct each other’s movement. The basic rule is very simple: you cannot go back to a square already visited by a snake. The winner is the snake that is able to move around freely for the longest.
Required material: CodyRoby cards, a 5 × 5 chequered board, two pawns, and pieces of paper to be used to mark the boxes already visited.
