## What is スパイラルリバーシ?

Spiral Reversi is Reversi played on a long strip wound around a tube in a spiral.

The end of each lap runs straight into the start of the next. Lines keep going across the seam, so long runs appear that a flat board never has, and a single move can flip dozens of stones. There are only two corners: the two ends of the strip.

HOW TO PLAY
- Sandwich your opponent's stones to flip them to your color
- Lines count across, down, diagonally, and across the seam
- Legal moves are marked, so you can start right away
- The tube and the unrolled strip are shown side by side
