Tower Defense is a free tactical wave-survival strategy game you can play instantly in your browser — no download, no install, no sign-up. Place and upgrade towers along a glowing tactical grid, deploy timed abilities, and survive wave after wave of attackers across a campaign and an endless mode. Plays on phone (in landscape) and on desktop.

How to Play

• Buy towers from the shop on the right and place them along the enemy path.
• Upgrade between waves — tap a placed tower to spend gold on damage, range, or special effects.
• Use abilities at the right moment to handle dangerous waves and bosses — airstrikes, slows, and overdrives.
• Survive every wave to protect your base; lose all your lives and the run ends.
• Controls: tap or click to select and place towers; on phones, the game is designed for landscape.

Tips & Strategy

• Cover corners with splash. Enemies pile up at turns — a mortar or splash tower at a corner shreds groups for the price of one.
• Mix tower roles. Rapid-fire towers handle swarms; snipers pick off armored singles; slows give everything else more time on target.
• Save abilities for danger. A free Overdrive is wasted on a trash wave — bank it for the boss or a swarm that's leaking lives.
• Upgrade before you build wide. A single fully-upgraded tower often out-damages two cheap ones at the same gold cost; tall before wide.
• Read the Intel panel. Before deploying a wave, check what's coming — air units need anti-air, armor needs piercing, swarms need splash.

About the Game

Tower Defense is a classic tactical wave-defense game with a clean, neon-on-deep-blue command-grid aesthetic. If you enjoy strategy puzzles, lane defense, or the timeless "place towers, hold the line" loop, this is a satisfying, free take on the genre. The campaign delivers a 12-wave arc with boss fights, and endless mode lets you push your run as far as your build can take it. Runs on phones, tablets, and desktops — best in landscape on mobile.
