Alkkagi Rules

Alkkagi is the digital take on the Korean childhood game of flicking go stones across the floor. The skill is in judging angle, power, and collision geometry.

Square 600x600 board (virtual units). 4 stones per side, radius 30 units. A deterministic physics simulator handles collisions and friction.

• Press and drag one of your stones to set the launch vector.
• Release to fire in the direction opposite the drag, scaled by drag distance.
• After firing, input is locked until the simulation settles.

Knock all 4 opponent stones off the board. Knocking your own stones off is allowed but carries the obvious risk — sometimes it's worth it if the opponent goes off too.
