Tower Siege

Tower Siege challenges you to build a vertical fortress and survive relentless enemy assaults. Between waves, you strategically place defensive blocks to strengthen your structure. Then, prepare for the onslaught of goblins and siege engines. Manage your resources, upgrade your technology, and test your limits in this fast-paced arcade game.

Gameplay Focus

You receive a hand of four defensive shapes each round, such as walls, archers, cannons, mortars, or tesla coils. You have a brief window to place them on your tower. When the wave begins, enemies attack, and physics-based destruction takes over as unsupported blocks crumble and fall.

What Stands Out

The game combines tower defense with physics-based destruction. Falling rubble can crush enemies below, adding a strategic layer to block placement. You spend wood, stone, and gold to build and upgrade, unlocking a tech tree to face tougher foes like boar-beasts and bone knights. It is a compelling free io tower defense game with deep strategy.

Helpful Tips

Place heavy cannons and mortars on sturdy foundations to prevent collapse. Use walls to protect fragile units. Watch for siege engines that out-range your defenses and plan your tech upgrades to counter them. Efficient resource management is key to surviving deeper waves.
