Each round gives you a new target number. Reach it using the buttons you have, then prepare your calculator for the next challenge. Charges are limited, and the fewer turns you take to solve a round, the more coins you'll earn for new purchases.

Choose a calculator with its own unique features, expand its casing, and install new buttons. Reverse numbers, replace digits, take square roots, or swap your result with the target. Sometimes, a single well-chosen purchase opens up a whole new way to tackle each round.
Passive upgrades change the rules. Earn coins by reaching certain numbers, recharge buttons when you earn coins, or restore glass buttons after a round. Choose upgrades that suit your calculator and make them work together.
