For parents and teachers
Explore how weight and distance from the pivot affect balance. The shape weights are circle 1, triangle 2, bird 3 and square 4. Bars and strings weigh zero in the model. A hanging branch counts as the sum of its shapes. A bar balances when the total of weight times distance is equal on both sides.
Each level has five randomized puzzles. Levels 1 and 2 use a fixed pivot. Level 3 adds hanging groups, moving the pivot and connected bars. After a correct answer, the game moves on after two seconds. Tap Pause to keep looking at your solution.
Build your own mode supports up to seven bars across three tiers. Remove takes off the lowest shape on the selected hook, or removes a hanging branch. Undo restores the last change.
