Playing Rules

  • Objective: Eat food to grow your snake and earn points. First to reach the winning score (default: 1000) wins.
  • Player Snake: Green (Human). Controlled with arrow keys or on-screen buttons (mobile).
  • AI Snake: Yellow (AI). Moves automatically to chase food and power-ups.
  • Modes:
    • Player vs AI: You control Human against AI.
    • AI vs AI: Watch Human and AI compete.
  • Game Speed: Increases as total score rises (every 150 points). Super/shrink food temporarily slows the game.
  • Obstacles: Obstacle that move every 30 seconds. Avoid them to prevent collisions.
  • Cannon: A moving cannon ("The Cannon") chases the closest snake, with its barrel facing its movement direction. It shoots projectiles every 30 frames. If hit, the snake grows by 1 segment, loses 1 point (if score > 0), and the cannon gains 1 point. The cannon’s score is displayed as "The Cannon: $X".
  • Collisions: Hitting obstacles, yourself, or the other snake triggers penalties, a 30-frame invincibility period, and specific sounds:
    • Self-Collision: Lose half your score (rounded down), other snake gains it.
    • Snake Collision: Lose all your score, other snake gains it.
    • Obstacle Collision: Lose 80% of your score (rounded down), other snake gains it.
  • Wrapping: Snakes wrap around screen edges for continuous movement.
