About this game

Numbers are coming. Do the math.

Geometry TD is a tower defense unlike anything you have played: the enemies are living numbers, your towers are geometric shapes, and a million projectiles can light up the screen at once. Merge matching towers to grow them from a single Dot all the way to the Octagon and beyond. Every merge triples their firepower, and arranging towers of the same element into triangles, squares and larger patterns unlocks even bigger bonuses.

You are not alone out there. Hire a crew of hardworking astronauts who fly across the map for you: they build your new towers, mine the asteroids that block your grid, and collect the shards that fall from defeated numbers. Give them orders or let them pick their own jobs, and watch them level up with every task they finish.

Features
  • Seven elements with real matchups: fire, poison, ice, electric, air, water and mud. Every enemy has a weakness waiting to be found.
  • A cheerful astronaut crew that builds, mines and collects while you plan the defense.
  • Waves that keep you on your toes: Rush, Swarm, Armored and Blitz attacks, a boss showdown every tenth wave, and run-long boons that make every game feel different.
  • One endless run: jump straight in, survive as long as you can, chase your best wave, and watch the numbers climb into the billions.

Geometry TD is in active development, and rich new features are on the way. No timers, no pay-to-win: just you, your crew, and an endless tide of numbers.
