Calculate It

Calculate It is a roguelike built around solving number targets with a calculator. Each round gives you a target and a set of buttons; reach the target, then prepare for the next challenge. Charges are limited, and solving a round in fewer turns earns more coins to spend on purchases.

Build your calculator

Choose a calculator with its own features, expand its casing and install new buttons. Buttons let you reverse numbers, replace digits, take square roots or swap your result with the target. A well-chosen purchase can open up a different way to solve rounds.

Passive upgrades change the rules and can work together with your calculator and buttons. For example, you can earn coins by reaching certain numbers, recharge buttons when you earn coins or restore glass buttons after a round.

Adapt to challenges

Bosses can disable specific buttons, raise charge costs or hide the calculator's display. You need to preserve useful tools and find other solutions when your usual combination no longer works.

Other challenges change the conditions of a run: use a calculator that loses a button after each round, race against the clock, decipher operations hidden behind alchemical symbols, or play Only Up, starting at one and working toward targets around ten thousand.

Runs and progression

Win runs to unlock buttons and passive upgrades, take on higher difficulties and continue a successful build in Endless Mode.
