Rubik's 3x3 Keyring and Triamid
Rubik’s 3X3 Cube Keyring is the exact same and incredibly addictive, multi-dimensional challenge that has fascinated puzzle fans around the world since 1980... but much smaller. The Rubik's Triamid is as difficult as rich in combination as the classic 3x3 cube itself. Keep splitting the Triamid in half, rotate, then put it together again. Solve it by having each side its own colour. The geometry is novel, the moves revolutionary-within 3 steps you are hopelessly lost.
