Crack those knuckles and dust off the mind - it time to test your visual speed and memory! Each player (up to 4) gets a tray with 16 cubes. The cubes all have the same arrangement of patterns on each ride: dots, solids and triangles. In round 1, the top pattern card is turned over and players race to match the pattern. First player to correctly do so wins the card. Round 2 is slightly different: flip the card over and then roll all of your cubes like dice, using only the side that's rolled up. You can re-roll as much as needed, but only the fastest player will win! In round three, players get 10 seconds to memorize the card, and then must use any side of their cubes to recreate the pattern from memory. The player with the most cards after 3 sets of 3 rounds wins the game. Speedy and challenging, it is easy to learn, but challenging to play. 120 pattern cards are included.
