Time Blocks

From the Publisher:

Time Blocks is a block stacking game that will surely challenge the whole family. It is fast paced and will summon your powers of shape and color recognition, not to mention building skills. Flip over a card, find the correct blocks and replicate the structure shown. But hurry... you only have a minute and some of the configurations are devilishly difficult to build. Younger children can play the game by duplication the pattern on the card flat on the table top. Game includes 28 hardwood colored blocks, 1 sand timer and a deck of 100 game cards."

Ages 7 to adult
