This is an addictive and brilliant puzzle game that challenges the player to fit all 5 of their clear acrylic gear puzzle pieces onto the puzzle card by matching the colors of the gear icons to the design on the card. This game includes a deck of 60 spiral-bound puzzle cards that get progressively more difficult and if you get stuck or when you need to check your progress, the solutions are shown at the end of the booklet. The first levels start out easy by matching shapes/colors and then higher levels proceed with less hints and have many more challenging variables. Each puzzle only has one correct solution. Can you find them all?? One player game, ages 6+. Quiet play, compact and great for travel!
