About this game

Two expressions. One scale. Which side wins?

MindScale turns mental arithmetic into a fast, satisfying comparison game. Look at the expression on the left, look at the expression on the right, and decide: is Left less than, equal to, or greater than Right? No calculator, no scratch work required — just your instincts (though a scratch pad is there if you need it).

TWO WAYS TO PLAY 🎯 Classic — no clock, no pressure. Work through rounds at your own pace and build your streak. ⚡ Arcade — race a countdown timer, guard your 3 lives, and chase combo multipliers before time runs out.

THREE LEVELS OF CHALLENGE Start on Easy with simple addition and subtraction, work up to Medium's multiplication and division, and test yourself on Hard's multi-term expressions with parentheses.

BUILT-IN HELP WHEN YOU NEED IT Stuck? Hint reveals one side's value. Solve shows you the full answer. Either way, you keep playing and keep learning.

TRACK YOUR PROGRESS See your accuracy broken down by difficulty, chase your best streak, and watch your mental math get sharper the more you play.
