My sister and I can't remember the name of a game we had as kids and it's driving us crazy! We had it about 30+ years ago. It was based on copying tangrams off a card in a certain amount of time. Players used red and white plastic cubes to recreate patterns from cards that were placed in a revolving tower. Each player got a glimpse of their card as it went by each time and needed to remember their pattern and try assembling their cubes in that pattern. We really enjoyed the game but for the life of us we can't think of what it was called. Any help? Thanks.
