Tower Defense

Build arrow, cannon and frost towers beside a winding road and hold the gate against twenty waves of enemies.

Tower Defense

Enemies march along a winding road towards your gate. Build towers on the grass beside the road, upgrade them as the gold comes in, and stop every last one. Survive all 20 waves to win.

How to play

1. Choose a difficulty and press Start game.
2. Pick a tower below the field, then tap grass squares to build it.
3. Press Start wave 1 when your defence is ready.
4. Between waves a 15-second countdown runs. Call the next wave early for a bonus, or use the time to build.
5. Tap a tower to upgrade or sell it.

Towers

Tower, Cost, What it does

Arrow, 50 gold, Fast single shots at the enemy furthest along the road

Cannon, 90 gold, Slow shells that burst over an area; armour blocks less of their damage

Frost, 70 gold, A pulse that chills and slows every enemy in range

Every tower can be upgraded twice. Selling a tower returns 70% of the gold it cost.

Tips

Put towers where the road bends back on itself, so one tower covers two stretches. Frost in front of a cannon keeps enemies inside the blast for longer.
