About game

Matching games hit differently when you add space-faring felines to the mix. Merge Cosmocats - Defend the Tower keeps your brain busy as you drop fuzzy critters onto a grid to clear waves of alien invaders. You drag these creatures left and right to line up identical icons, triggering a chain reaction that fuels your main weapon. Every successful match powers up your cannon, letting you blast enemies before they reach your base. You need to balance the board space carefully because letting things stack too high leads to a quick game over. Fast decision-making becomes critical since each level shrinks your allotted time to think. Spending coins on upgrades like double shots or auto-fire helps you stay ahead of the escalating difficulty. Playing Merge Cosmocats - Defend the Tower is a blast, so load it up in your browser today without any downloads required.

How to play

Controls: tap or click to hold a cosmo-cat in the spawn zone. Move left-right to aim. Release — the cosmo-cat drops. If you don't release before the timer runs out, it drops automatically.

Mechanics: two identical cosmo-cats merge into the next level when they collide. To charge the cannon — merge cosmo-cats: every 3 merges of the same level grant one charge. Tap the Fire button or use the auto-fire upgrade to shoot enemies. Enemies move down toward the tower — don't let them reach it.

Game over: if cosmo-cats fill the field above the line and stay there, the game ends. Difficulty level drops by 1. You can watch an ad for a second chance — the field partially clears and you continue with your current score.

Shop: during pause, buy upgrades for coins (earned from combos). Upgrades last until the end of the current run.
