  • Summary
    • Cannons are a defensive building in the Builder Base. They are unlocked at Builder Hall level 2 (they are fixed from their ruin), and are the first defensive building in the Builder Base.
    • Cannons are both cheap and quick to upgrade at lower levels.
    • Cannons can shoot any ground units, such as Raged Barbarians, but not any air units, such as Beta Minions or Baby Dragons.

  • Defensive Strategy
    • Cannons have a high rate of fire and a decent range.
    • Cannons are very good point defenses that can deal massive damage to ground tanks, as long as they are protected.
    • You can defend with splash damaging defenses such as Multi Mortars and Crushers by placing them within range of Cannons.
    • Make sure Cannons are placed within range of Firecrackers or Air Bombs, because Cannons are unable to target air units.
    • Upgrade these structures first at lower levels, as they are one of your main ground defenses. They are also the cheapest and one of the most common defensive structure available, which makes them a good initial investment.
  • Offensive Strategy

  • Upgrade Differences
    • Cannons undergo significant changes at levels 2, 3, 4, and 7. Their upgrade differences correspond to Cannons in the Home Village of equal level.
      • At level 1, the Cannon consists of a short dark metal barrel mounted on a crude, four-legged wooden platform.
      • At level 2, the Cannon's base receives a wooden stabilizer tied to the legs with ropes.
      • At level 3, the Cannon's leg stabilizer becomes stouter and the Cannon becomes larger. The base itself rotates 45 degrees within the 3x3 square (ostensibly to accommodate the later, larger upgrades of the Cannon).
      • At level 4, the Cannon barrel receives two decorative latitudinal ridges, one midway along the barrel and one at the rear. The platform's leg stabilizer is removed in favor of a larger and stouter main support platform with much shorter legs.
      • At level 5, the Cannon base's wooden legs are replaced with metal ones and its metal ring which it pivots on gets wider.
      • At level 6, pieces of metal bolted by a metal bolt are added to the side of the Cannon.
      • At level 7, the wooden base is discarded for a white stone or metal platform with four short brass-trimmed legs. The Cannon barrel's decorative center ridge is trimmed with a ring of brass.
      • At level 8, the other decorative ridge around the rear of the barrel also receives brass trimming, as well as a pair of opposing brass straps or clamps securing it to the platform.
      • At level 9, the Cannon receives a third brass-trimmed decorative ridge around the muzzle of the barrel, and two additional brass straps or clamps perpendicular to the first pair. The straps or clamps also receive a bolt on each end.
    • The appearances of the cannonball changes with level, along with its size.
      • When first constructed, the cannon shoots small, light grey color balls.
      • At level 2, it shoots bigger balls.
      • At level 4, the balls becomes even bigger and becomes darker.
      • At level 6, it gains spikes around the ball.
      • At level 7, the ball becomes bigger again.
      • At level 8, the ball that is shot now glows.

  • Trivia
    • The Cannon is automatically repaired when the player upgrades to Builder Hall level 2, even though the Master Builder does not appear to repair it.
    • When viewing your village, the Cannons will appear to aim randomly about. However, they will mostly be aiming away from the Builder Hall. If the Cannons (or the Builder Hall) are moved, the Cannons will instantly orient themselves to point away from the Builder Hall's new relative location. This remains true even when the Cannons are being upgraded, though it will not move.
    • The Cannon's barrel expands slightly whenever it shoots.
    • The Cannon in the Builder Base has more damage and hitpoints than the Cannon in the Home Village.
    • In the description, it states that the Cannon makes the Master Builder feel sentimental. This could mean whether he used to be in Home Village or the Cannon in Builder Base is his first project.
    • The Cannon is one of the two Defensive Buildings (the other being Hidden Tesla) which has a same texture with the Home Village counterpart in every level.
