Scale Sleuths

Scale Sleuths is a multiplayer math review game for grades 3–8. Crack balance-scale logic puzzles: every shape has a secret weight. Use the balanced scales to figure out what each mystery shape weighs.

Skills: Will it balance?, one mystery shape, two and three mystery shapes with substitution, unknowns on both sides, writing the equation for a balance.

New problems every game, with Easy, Medium and Hard levels. Every miss shows a short explanation, and a read-aloud button reads any question out loud.
