Play this game alone, or with several players. Place the 15 Crilo cards randomly with hook velcro side uppermost, spaced out on the floor. Then take turns rolling the Crilo ball (the size of a tennis ball, & covered in velcro loop texture) from a distance of about a metre. Try to roll over as many Crilo cards as possible. Each turn, remove & keep the cards that stuck to the ball. Score based on the cards you won. Full instructions included. Why not buy an extra pack, & increase the possibilities in your game?! Great fun for all ages, & particularly useful for teaching simple adding skills.
