Merge Defense: Cube Blocks TD

Merge blocks, build the ultimate defense, and crush the cube army — Merge Defense: Cube Blocks TD is the merge tower defense game where every merge doubles your firepower.

Waves of enemy cubes march down the grid. Your job is simple: place blocks, merge blocks, upgrade your turrets, and never let a single cube reach your base.

🔥 MERGE BLOCKS, DOUBLE YOUR FIREPOWER
Drag two identical blocks together and merge them into a stronger turret. Each merge unlocks a new tier of block with heavier damage and faster fire rate. Easy to learn, hard to master — that is the heart of classic merge defense.

🛡️ CUBE DEFENSE: SURVIVE EVERY WAVE
The cube army never stops. Every wave is faster, tougher and denser than the last, and boss cubes hit like a truck. Hold the line with a smart block defense, or watch your base fall in seconds.

⚔️ REAL TOWER DEFENSE STRATEGY
This is not a mindless tapper. Every tile on the grid matters. Do you spread out many low-tier turrets for wide coverage, or funnel everything into one monster block? Choose your defense strategy, adapt to each wave, and out-think the cube rush.
