# Bank Shot

GCD · 30 levels

Bank the ball off the cushions into the called pocket.

## How to play

- The ball rolls at 45°, bouncing off the cushions until it drops into a corner pocket.
- Change the rail lengths with − and + (or pick the cue spot and aim), then press Shoot.
- Sink it in the glowing pocket, and when asked, in exactly that many cushions.

From a corner on a p × q table, divide both sides by their GCD. Odd and odd: the opposite corner. The ball bounces p/g + q/g − 2 times.
