Build towers, burst the lane, and survive wave after wave.
Place towers on the glowing pads, choose your upgrades, and keep the route clear as the waves keep coming. Every upgrade makes the line hit harder, reach farther, and push back a denser wave.
Tap glowing pads on the board to place towers. Tap a tower to select it, then use the in-board buttons to upgrade, expand the board, or restart the run. Keyboard shortcuts include U for upgrade, F for expand, and R for restart.
Hold the lane
Put towers where the route bends and keep the front line covered as the enemies get faster and tougher.
Upgrade the line
Each tower level makes the shots stronger, the range wider, and the bursts denser, so a good position keeps paying off.
Feel the pressure rise
Later waves bring more enemies and heavier threats, so every new push asks for a smarter setup than the last one.
Place, upgrade, and keep the lane alive.
Tap a glowing pad to build a tower. Tap the tower again to select it. Use the board buttons to upgrade it, expand the board, or restart the run when you want a fresh climb.
- Build where the lane bends to catch more enemies at once.
- Upgrade selected towers to unlock bigger bursts and better coverage.
- Expand the board when you want the lane to fill the whole screen.
The lane never stops. New waves keep arriving, mixed enemy types push through in larger numbers, and the route steadily gets more crowded as your run stretches on.
That keeps the game readable and immediate: every new tower, burst, and upgrade changes the fight in a way you can feel instantly.
The game keeps leaning forward: stronger enemies, fuller waves, and bigger reward moments as your defense line gets more polished.
What changed in the latest rounds
The lane turned vertical
The battlefield now runs top to bottom, so the route feels longer, tighter, and easier to read on a phone.
Board controls stay with the fight
The upgrade, restart, and expand actions now live inside the board, so you never have to leave the game to keep playing.
Burst fire feels punchier
Towers now fire in bursts with multiple shots, which makes every upgrade feel more powerful and more visible.
The run keeps building
Later waves bring more enemies, tougher enemies, and a steadier push so every session feels like a fresh climb.
Common questions about the run
How do I build a tower?
Tap any glowing build pad inside the lane. The pad cost is shown on the board, and the tower you place becomes part of the line automatically.
How does the upgrade system work?
Select a tower and use the upgrade button inside the canvas. Each level adds more range, more damage, and denser bursts, so the same tower keeps growing with the run.
Can I keep playing forever?
Yes. Waves keep scaling up, enemy mixes get tougher, and the shield rebuilds itself when it runs out, so the run never hard-stops.
Does expand mode work on mobile?
Yes. The board expands inside the page and can shrink back again without leaving the run.
The lane keeps tightening as you climb.
The route runs downward, the upgrades stay in the board, and every new wave asks for a cleaner line, a stronger tower, or one more burst of damage.
