Cannon — Free Online Artillery Game
Cannon is a free browser game that pits you against a CPU opponent in a classic artillery duel across destructible terrain. Each turn you set your cannon's firing angle and shot power, then watch your projectile arc through the air. Land a direct hit and you chip away at your opponent's health bar; miss and the shell carves a crater into the landscape, permanently reshaping the battlefield. The first player to drain the other's HP to zero wins the duel. Play unblocked right in your browser with no download required.
What makes Cannon compelling is the wind mechanic. A wind indicator at the top of the screen shows both direction and strength, and every shot is affected by it. A strong crosswind can push your shell several squares off-target, turning a shot that looked perfect into a near-miss. Learning to read the wind and compensate with your angle is the difference between a rookie who sprays shells all over the map and a veteran who lands precise hits consistently. The terrain is also your ally — hills and valleys can provide cover or create favorable angles that a flat battlefield never would.
How to Play
Taking Your Shot
- Use the angle control to aim your cannon — higher angles produce steep arcs, lower angles produce flat trajectories.
- Set the power level to control how far the shell travels before gravity pulls it down.
- Press the Fire button to launch. Watch the shell's arc carefully to judge how far off-target you were.
- The CPU takes its turn immediately after you fire, so be ready to see a return shot.
Reading Wind
- The wind arrow shows which direction the breeze is blowing and how strong it is.
- Wind blowing toward the opponent pushes your shell further — reduce power slightly to compensate.
- Wind blowing against you shortens the range — increase power or steepen the angle to reach the target.
- Wind can shift slightly between rounds, so check the indicator before every shot.
Tips & Strategy
Bracket Your Shots
If your first shot lands short, increase power on the next shot. If it flies long, reduce power. Use the previous shot's landing point as a reference to zero in quickly. Most players find the correct distance within two or three attempts once they adopt a systematic bracketing approach instead of guessing randomly.
Use the Terrain for Cover
If you are tucked behind a hill, the CPU will need a high-arcing shot to clear the ridge and land on you. That gives you a natural advantage because even a slightly miscalculated shot will hit the hillside instead of your cannon. Stay behind terrain whenever possible and use steep angles to loft shells over obstacles.
Aim for Body Shots, Not Craters
Shells that land slightly short of the opponent create craters next to them without dealing full damage. Aim for a direct hit on the cannon itself rather than landing just in front of it. A well-placed shot deals maximum damage and forces the CPU to operate from a damaged position.
Adapt When the Landscape Changes
Every explosion reshapes the terrain. After a few rounds the battlefield looks very different from the start — craters can lower the ground in front of your cannon, exposing you, or create ramps that change shot trajectories. Reassess your position after each exchange and adjust your angle accordingly. Cannon is one of the best free online strategy-arcade games available with no download needed.
