Stretch your mental muscles into the third dimension! In this version of Ubongo, the hit puzzle game, players race to place three-dimensional blocks so they fit perfectly in a specific area on a puzzle card and completely fill a designated three-dimensional space. Each time you win, you collect colorful plastic gems; the player with the most valuable collection of gems at the end of the game wins. The puzzle cards each have multiple puzzles on both sides: one side is easier, the other more difficult. A total of four difficulty levels makes this the perfect game for beginners and experts alike, allowing the whole family to play together. With four sets of eight durable three-dimensional pieces and 72 puzzle boards featuring a total of 671 puzzles, the game can be played with up to four players — or challenge yourself in solo games. Take your puzzling to the next level with Ubongo 3D.
