BiModal Architectural Blocks


Stack 'Em If You Can!

It's the cure for the common cube! BiModal blocks expand a child's understanding of spatial relationships by engaging them with uncommon shapes. Kids will stretch their imagination as they try to recreate familiar figures, such as letters and animals, or build modernist structures never before conceived!

The blocks also lend themselves to countless games that challenge a child to think strategically in 3 dimensions. See who can build the taller tower in Tower Tumble or the stronger fortress in Big Bad Wolf. These games and more are detailed in the accompanying manual, although you and your child will probably end up devising a few of your own. Whether you choose to build, play, or just put on them on display, these delightfully unusual blocks are fun no matter how you stack them.

Game Examples:
Tower Tumble
2 players. Start a tower base with 3 large pieces. Take turns stacking pieces on the tower. As the tower rises, it will get harder and harder to keep it from falling over. The player who makes the tower tumble loses the game.

Big Bad Wolf
2–3 players. Each player selects 4 blocks and stacks them one on top of the other from the largest on the bottom to the smallest on the top. After each player finishes his or her stack, they switch places, moving one seat to the left. Then, in unison, each player tries to "blow the house down." Each player can choose to stand or sit, but they must be at least one foot away from the stack and cannot use anything other than lung-power. If no stack tumbles, each player moves back to their original seat and adds a block. They repeat the process until all but one stack is blown down. The player with the last intact stack wins!
