About this game
Merge Defense is tower defense with a merge twist. A shop offers random tower tiers — buy smart, then drag one tower onto another of the same level to fuse them into the next tier: Arrow, Ballista, Chu-Ko-Nu, Piercer and the chain-lightning Thunder tower. With only eight pads along the S-shaped road, every purchase and every merge matters. Enemies grow tougher every wave and a boss marches in every fifth. Sell for seventy percent back, keep the gold flowing and chase the strongest chain.
How to play
Tap the shop to buy a tower onto a free pad. Drag one tower onto another of the same level to merge them into the next tier. Double-tap or hold a tower to sell it for seventy percent. Survive as many waves as you can.
Tips & Tricks
- Merging is cheaper than buying high tiers — build a pair of level ones first.
- Keep one gold buffer for emergencies — a mistimed shop refresh loses waves.
- Place your strongest tower near the middle of the road for maximum coverage.
- The Thunder tower chain lightning shines against tight clumps — save it for boss waves.
Frequently asked questions
How do I merge towers in Merge Defense?
Drag one tower onto another of the exact same level. They fuse into the next tier and keep the pad. Towers of different levels cannot merge.
What happens when I run out of lives in Merge Defense?
Every enemy that reaches the end of the road costs one life and a boss costs three. When all ten are gone the run ends and your score is saved.
