This logic puzzle is designed for ages 8 and up, with 25 challenge cards that range from easy to difficult. The set includes 12 colorful wooden blocks, a laser-cut wooden tray, puzzle cards with color labels, and quick-start instructions. Players arrange the blocks according to the card's layout, then use the clues to figure out where the remaining colors go—the solution is on the back of each card for checking answers. The puzzle comes in vibrant packaging and makes a thoughtful gift for kids or adults. Its high-quality wooden pieces and stylish design also make it a nice decorative piece for a table or bookshelf. Project Genius, the creator of this puzzle, has been making mechanical puzzles and strategy games in the U.S. for over a decade.
