## What is Block Siege?

Block Siege is a new kind of tower defense that combines puzzle mechanics, block placement, and strategic combat.

In this game, you do not simply place towers on a fixed map—you design the path the enemies must travel. Use falling blocks to extend, bend, and reshape the route of invading monsters. The smarter your block placement, the longer the path becomes, and the more time your towers have to attack.

Once the path is built, deploy a variety of defense towers directly on the blocks. Choose from cannons, lasers, and missile turrets to destroy enemies before they reach your base. Merge two towers of the same type to create a stronger, upgraded version with higher damage and unique abilities.

The challenge increases with each wave. Enemies become faster, stronger, and more numerous. Only creative block paths, smart tower placement, and powerful merges will allow you to survive.

Features:

* Innovative blend of tower defense and puzzle gameplay
* Shape enemy paths by placing blocks strategically
* Deploy and upgrade towers on top of blocks
* Merge two towers to unlock stronger, upgraded weapons
* Battle against varied enemy types and bosses
* Endless replayability with new strategies every run

If you enjoy tower defense, puzzle strategy, and merge mechanics, Block Siege delivers a fresh challenge that rewards creativity and planning. Build, merge, and defend your base against relentless monster waves.

Download Block Siege today and experience tower defense like never before.

### 2/5 — Has potential.

*2025-11-02*

I was able to play for a while after downloading the game, but then I got stuck on the home screen with frozen buttons and couldn’t resume gameplay. I really like the concept and hope an update fixes this issue soon!

### 1/5 — Game stuck

*2025-10-16*
