Geometry Tower Defense
About Geometry Tower Defense
Geometry Tower Defense is a free online strategy game that puts a sleek, minimalist spin on the classic tower defense formula. Set against a glowing neon backdrop, waves of geometric enemies creep along a winding path toward your base, and it's your job to stop them before your hearts run out. Build hexagonal towers along key chokepoints, manage your gold carefully, and upgrade your defenses on the fly to survive increasingly aggressive enemy waves. Developed and published by MarketJS, the game is built around six distinct tower types, each with its own strengths against the enemies swarming your path.
Geometry Tower Defense runs directly in your browser on desktop, iOS, and Android devices, with no download or account required. The clean, geometric art style keeps the action easy to read even when the screen fills up with towers and enemies, making it simple to pick up but genuinely challenging to master as the waves escalate.

Tower Types
Your arsenal in Geometry Tower Defense revolves around six distinct hexagonal towers, each suited to a different role on the battlefield. The Basic Tower offers reliable, low-cost damage that's perfect for early rounds, while the Rocket Tower and Burst Tower trade higher gold costs for area-of-effect power against grouped enemies. The Sniper Tower deals heavy single-target damage at long range but reloads slowly, rewarding players who place it where it can pick off tough targets without interruption. The Shock Tower and Laser Tower round out the roster with unique effects for players looking to experiment with different defensive combinations. Every tower can be upgraded for increased damage and fire rate, or sold back for partial refunds when you need to rework your layout mid-wave.
Strategy and Gold Management
Success in Geometry Tower Defense comes down to reading the path and spending your gold wisely. Early waves are forgiving, giving you time to establish a core defense around the tightest bends in the road, where towers get the most exposure to incoming enemies. As gold builds up, prioritize upgrading your strongest chokepoint towers rather than spreading resources too thin across weaker placements. Keep an eye on each tower's targeting priority, since switching between nearest, strongest, or first-in-line enemies can make the difference during a chaotic wave.
Tips for Winning at Geometry Tower Defense
Save your gold for a strong opening rather than spending it all on the first towers you unlock — a well-placed Sniper or Rocket Tower at a chokepoint outperforms several scattered Basic Towers. Use the speed toggle to fast-forward through slower early waves and save your full attention for the tougher rounds. Pause whenever you need a moment to reassess your layout, and don't be afraid to sell an underperforming tower to fund a better placement elsewhere. Watch your heart count closely in the top-left corner — losing track of it is the most common way runs end early.
How to Play Geometry Tower Defense
- Start the level — Press Ready to begin sending enemy waves down the path toward your base.
