Snakes

Snakes is a two-player game on a square grid. Red starts by laying a single egg (one square). From then on, each player places two squares per turn (Blue goes next).

When you fill a square:

• If it doesn't touch any end of your snakes, a new egg is born.
• If it touches the head or tail of one of your snakes, that snake grows to the new square (an egg becomes a 2-square snake).
• If it touches ends of two of your snakes, the one you modified last grows.

Your opponent's squares don't interact — they just take up space. The game ends when the board is full. The longest snake wins. Equal lengths means a draw.

Levels: 4×4 · 5×5 · 6×6.
