About Cannon Defenses

Cannon Defenses is a merge-based tower defense game in which cannons guard the bottom line from advancing enemies. Waves include regular attackers, tanks, and bosses, so building a stronger defensive arrangement is central to surviving the assault.

You begin by creating basic turrets, then combine matching pieces to turn the available firepower into more capable weapons. The endless structure keeps the pressure on while new tiers provide a reason to organize the cannon line carefully.

How to Play Cannon Defenses

Use mouse or touch input to buy a cannon and place a new unit on the field.

Move one cannon over another matching cannon to combine them into a stronger turret.

Drag a cannon into an open slot when your defensive layout needs repositioning.

Keep the line protected as enemies travel toward the bottom boundary.

Spend your available pieces thoughtfully, balancing new units with combinations that improve existing firepower.

Tips & Tricks

1Leave useful empty spaces so cannons can be moved when the attack pattern demands a different arrangement.
2Combine matching turrets when a stronger weapon will cover the threatened part of the line more effectively.
3Pay attention to tanks and bosses, since their presence calls for a defense that is stronger than a scattered group of basic cannons.
