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.
1. Click the download button to start.
2. When the download is complete, right-click the .rar file and select 'Extract to current folder'.(If you run into any errors while extracting, make sure you’re using WinRAR or 7-Zip.)
3. Open the unzipped folder, find the .exe file, and double click it to run. (If there's a _Readme.txt in the folder, it's probably worth checking out.)
4. Enjoy. If you get any missing .dll errors, check for a 'Redist' or '_CommonRedist' folder and install everything inside.
