Goal: Destroy all of your opponent's pucks. You only lose when the other player destroys your last puck.

Setup: Each player places 2 obstacles in the front third of their side, then places 3 pucks wherever they want.

Each turn: You get ONE move — either fling a puck or move an obstacle.

• Fling: Drag your puck backward, then release. Pull opposite to the direction you want to shoot.
• Move obstacle: Click your obstacle, then click a new spot in your front third.

Hit opponent's puck: Their puck is destroyed. Yours keeps going.

Hit opponent's back wall: Your main puck splits into 2 that spread apart. Split pucks respawn randomly on your back wall when they stop.

Obstacles: Can only be placed in the front 1/3 of your side (closest to center).
