Calculate It Free Download

We turned a calculator into a roguelike!

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.

Create your own build

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.

Combine buttons and passive upgrades

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.

Adapt to the bosses

Bosses disable specific buttons, increase charge costs, and even hide your calculator's display. Save your useful tools and find new solutions when your usual combination stops working.

Take on unusual challenges

Complete a run with a calculator that loses a button after every round. Race against the clock. Decipher operations hidden behind alchemical symbols. In Only Up, start at one and work your way up to targets around ten thousand.

Win runs, unlock new buttons and passive upgrades, take on higher difficulties, and keep a successful build going in Endless Mode.
