Cannon Duel guide

What is this game?

Cannon Duel is a free turn-based artillery game (tank cannon game): adjust angle and power and account for the wind. It is a casual original, not official Fortress or Worms, and you can battle the AI with no sign-up.

The terrain is destructible — every shell digs a crater, so you can carve away hills or drop your rival into a pit for fall damage. Dump, Skip, Boom, and Snipe each have different mobility, health, firepower, and a unique special shell.

Play four maps (Hills, Plains, Canyon, Peak) and eight missions on PC, tablet, or phone, right in your browser.

How to play

On your turn, move and fire once. Set angle and power, account for wind, and reduce the enemy tank's health to zero first. At the turn limit, the tank with more health wins.

Each impact deals splash damage and digs a crater. If the ground under a tank is blown away and it drops a long way, it takes fall damage.

  • Dump: short movement, high health and firepower. Special: Driller digs a huge crater.
  • Skip: long, fast movement, lower health and firepower. Special: Triple shot fires three shells in a fan.
  • Boom: largest splash and less affected by wind. Special: Cluster scatters four bomblets.
  • Snipe: long range and heavy direct hits with tiny splash. Special: Precision round ignores wind.
  • Specials can be fired twice per match; each tank carries one Repair (30 HP), Boost (double move), and Calm (zero wind) item, with one item per turn.
  • AI difficulty is easy, normal, or hard. Harder AI aims and positions better and uses specials and items more actively.

Controls

  • Adjust position, set angle and power, then fire while checking wind direction and strength.
  • Drag on the battlefield with a finger or mouse to set angle and power at once, then release to fire. Drag back near your tank to cancel.
  • Switch to your special shell with its button (Q on PC) and use one Repair, Boost, or Calm item per turn (1·2·3 on PC).
  • The follow camera tracks and zooms on the shell; toggle sound/vibration and the camera from the top bar.

Strategy tips

  • Use the first shot to measure range, then change only angle or power so the correction is easier to read.
  • Shells dig craters, so aim under your rival to drop them into a pit for extra fall damage — and watch out when the hill protecting you gets blown away.
  • Staying put lets the AI walk its shots in and get more accurate. Spend your move gauge to relocate.
  • Dump's Driller collapses terrain, Skip's Triple shot forgives near misses, Boom's Cluster pressures a wide area, and Snipe's wind-ignoring Precision round finishes fights.

Difficulty differences

Easy has wider aiming error. Normal applies distance and wind more consistently and moves to better spots. Hard picks positions your counterattack struggles to reach, uses specials and items at the right moment, and gets more accurate against a target that stays still.

Common beginner mistakes

  • Ignoring wind and reusing the same angle misses repeatedly.
  • Forcing a direct hit on the first shot — use it to gauge the distance instead.
  • Camping only on high ledges leaves no room to adjust when you face a headwind.
  • Burning both special shells early leaves no finisher — you only get two per match.
  • Ignoring the crater under your tank invites fall damage on the next hit. Move out once it gets deep.

FAQ

Can I play a free Worms- or Fortress-style artillery game in my browser?

Yes. Cannon Duel on Playfulo is a free turn-based artillery game. It is not official Fortress or Worms. Adjust angle and power, account for the wind, battle the AI, and blow craters into destructible terrain.

How do destructible terrain and fall damage work in Cannon Duel?

Every shell digs a crater the size of its blast. If the ground under a tank is blown away and it falls from high up, it takes damage based on the drop. Aim under your rival or carve away the hill that blocks your shots.

What is the difference between Dump, Skip, Boom, and Snipe and their special shells?

Dump is tough and hits hard, and its Driller digs huge craters. Skip moves fast and fires a Triple shot. Boom has the widest splash and a Cluster shell. Snipe lands heavy direct hits and its Precision round ignores wind. Each special can be fired twice per match.

What is Cannon Duel's mission mode?

Missions are challenges with a fixed tank, map, and rules: a no-wind range, strong crosswinds, no moving, no items, and knockouts within a turn limit. There are eight missions, and your clears and best turn counts are saved on your device.

How do I choose AI difficulty?

Pick easy, normal, or hard. Hard AI chooses spots your counterattack struggles to reach, uses specials and items at the right time, and gets more accurate against a target that stays still.

How do I change angle and power when the wind is against me?

A flat angle that landed last turn falls short into a headwind. Raise the angle or add power and re-aim. If the ground has already collapsed, the same coordinates land at a different height, and a tank on the rim can fall for extra damage. Putting the opponent on the edge of a crater is often better than hitting the hull straight on.
