STACK SIEGE

Build higher. Survive longer.
Stack Siege is a fast-paced game where tower stacking meets tower defense. Stack blocks, arm your tower with weapons, and fight through increasingly dangerous waves of enemies.

Every new block takes your tower higher — but one bad placement can ruin a perfect build. While you focus on stacking, your mounted weapons automatically fire at incoming enemies.

BUILD YOUR TOWER
Place falling blocks as precisely as you can. Build a tall, stable tower, beat your best score, and push your maximum height higher with every run.

DEFEND YOURSELF
Enemies attack in waves, and your tower fights back. Mounted weapons automatically target incoming threats and protect your growing structure.

CHOOSE UPGRADES
Pick powerful upgrades as you progress and change the way your tower performs. Create combinations that help you survive the increasingly difficult waves ahead.

FIGHT BOSSES
Regular enemies are only the beginning. Survive long enough to face powerful bosses that put your tower and upgrades to the test.

GROW STRONGER
Every run contributes to your progress. Improve your abilities, unlock new possibilities, and come back stronger to build even higher.
Simple controls, quick sessions, and a mix of precision, strategy, defense, and progression.

How high can you build — and how long can your tower survive the siege?
