Tile city: under siege

About Tile city: under siege: Build, Upgrade, and Survive

Tile city: under siege puts your city directly in the crosshairs. The goal is straightforward and urgent: hold the line by constructing new facilities, strengthening your defences, and unlocking fresh perks and weapons before the pressure overwhelms you. In one scene, pink circles and red triangles press toward a central cluster of hexagons, giving a vivid sense of the waves bearing down on your position.

How to Play Tile city: under siege

The core loop revolves around three actions. Then drag that building onto any free cell on the grid. Finally, place two identical buildings next to each other and merge them — combining similar structures raises their effectiveness, letting your defences grow stronger as the siege intensifies. Unlocking new perks and weapons is also part of surviving the escalating assault.

Controls

• Button press: Buy a new building
• Drag: Place a building onto a free cell
• Drag identical buildings together: Merge them to increase their effectiveness

Merge Defense: Army Behind the Wall lets you buy warriors and merge identical ones — archers and mages grow more powerful as you travel through swamp, ice, desert, and mushroom forest worlds. For a lighter take on the same idea, Chicken Merge has you drag and drop identical chickens to fuse them into stronger defenders protecting your base from enemy hordes.
