I designed and 3D-printed slide rule calculator for Balatro!

It can quickly multiply and divide numbers to help you calculate your score.

This design is inspired by rotary slide rules from the 1930s, like the RotaRule by the Dempster corporation. My version has three octaves, so you can think in terms of thousands or millions if you need. The video briefly explains how to use slide rules of this type. You don’t need to be a math whiz.

If there’s interest, I’ll throw the STL files on Printables so anyone with a 3D printer can make one.

Good luck hitting those blinds on Ante 8! 🃏
