Tower Defense

Tower Defense is a free online strategy game you can play in your browser with no download and no sign-up. Build arrow, frost, and cannon towers along a winding road, then hold the line as waves of enemies march toward the exit. Spend your gold wisely, upgrade your best towers, and survive every wave on phone or desktop.

How to play

• Tap a green tile to open the build menu and place a tower for gold.
• Pick arrow towers for cheap steady damage, frost to slow enemies, or cannons for splash.
• Tap an existing tower to upgrade it or sell it back for gold.
• Press Start Wave when your defenses are ready, or send the next wave early.
• Killing enemies earns gold to fund more towers and upgrades.
• Every enemy that reaches the exit costs a life — lose them all and it is game over.

Place towers at bends and along the longest stretches of road so they get the most time to fire at each enemy. A single frost tower multiplies the value of everything else, since slowed enemies stay in range far longer. Upgrading one strong tower usually beats spreading gold thinly, and cannons shine against tightly packed waves thanks to their splash damage.
