Last year I made my own rotary slide rule for playing Balatro, the poker roguelike!

My version has a couple interesting properties compared to ordinary linear slide rules:

1. It has three octaves, so it can scale from 1 to 1k or from 1k to 1m, or from 1m to 1b. This is great for calculating point values

2. It's rotary

3. It can be easily 3d-printed!
