About Cannon Defenses

Cannon Defenses is a merge-based tower defense game where you combine cannons to build an unstoppable firewall. Enemies pour toward the bottom of the screen in endless waves—tanks, footsoldiers, and hulking bosses—and your job is to keep them from crossing the line. You buy basic turrets with earned coins, then drag matching cannons together to merge them into heavier firepower. Each merge unlocks a stronger tier, ramping up from rapid-fire starters to screen-clearing behemoths. Positioning matters, too; you can shuffle cannons between slots to focus damage where the crush is thickest. If you enjoy games on Poki Games that reward smart upgrades and quick decisions under pressure, this one delivers plenty of both. The waves never stop, so survival hinges on when you merge and where you place your heaviest hitters.
