Cannon Siege is a free turn-based artillery game set on a beach at dusk. You command a sandcastle cannon and trade volleys with rival castles across fully destructible dunes. Every shot carves real craters in the sand, the wind shifts each turn, and later levels pit you against two enemy castles at once. Win levels to earn Triple Shot, Boulder and Beach Ball ammo, then push your score as far as you can. It runs entirely in your browser — nothing to install, works on phone, tablet and desktop.

How do I play? Drag back like a slingshot and release to fire (or use the arrow keys and Space on desktop). Watch the wind arrow before every shot.

Q: Is Cannon Siege free? Yes — completely free in your web browser, no download or sign-up.

Q: Does it work on mobile? Yes, touch controls are built in for phones and tablets, portrait or landscape.

Q: Is my progress saved? Yes — your best score and highest level are saved locally, so you can continue where you left off.
