This tactical block stacking game challenges you to defy the laws of physics as you use the blocks to build a tower in unexpected and strategic ways. As the tower grows so does the suspense--who will topple the tower? It's so much more than stacking blocks. Use wits and strategy to force other players to make the riskiest move and force them to topple the tower. Players take turns playing cards that allow them to place a block, but only on the previous 2 blocks. Each card is worth points. When the tower falls, the last player who successfully placed a block gets all the points. Ideal for 2-6 players, ages 8 years old and up. Younger children love to play as well, but there is some basic math involved. Perfect game for families, couples, game night or parties. Everyone loves the suspense in BUILD UP. Game play time: 5-30 minutes. Game includes 20 Unique Wood Blocks, 20 Block Cards, 4 Action Cards, 1 Starter Card, 2 Rule Cards, and 1 Card Box. Recommended age 8+ years
