Gonge is a 43 year-old company that supplies nifty balance and play products to primary schools. They also havea pair of games called Mirror Game.

Each player gets 2 cubes with simple patterns for faces and a little mirror stand. A card is flipped over, and players have to form the pattern on the card using the cubes and the mirrors. Not too difficult, but looks like fun under pressure.

The red edition is for 4-7 year-olds, while the blue edition is for 6-14.
