Build, Balance & Spin!

Sometimes, Octacog seems to defy gravity. But actually, Octacog is using gravity to balance in peculiar ways. By learning about center of gravity and equilibrium, you can start to predict how Octacog will balance. Just like in life, some of the most fun discoveries are made when you try something new and something totally unexpected happens!

The last player to take a turn and spin Octacog without it falling or touching the balance pedestal wins! A fun way to experiment with observation, prediction and testing.

For one or more players. For ages 7+.

Play Rules:

Players take turns. During a turn, a player may add a part or move a weight one notch closer to the Octacog core. Before moving, player must declare an action. “I’m going to add a rod here,” or “I’m going to move this weight.” The player removes Octacog from the balance pedestal, performs the action and returns Octacog to the pedestal. The player gently spins Octacog. If Octacog makes one complete turn without falling or touching the balance pedestal, Octacog is balanced and it’s the next player’s turn. If Octacog falls or touches the balance pedestal or play surface, you lose.

Note: Octacog works best on flat, solid surfaces. Do not use Octacog on glass or fragile surfaces. Damage may occur.
