Description

Sphere TD is a tower defense game with one difference: there are no preset towers. You build every tower yourself by combining mods to spam more projectiles.

UNIQUE FEATURES

- Build & mod every tower. There are no preset towers.
- Defend each map with 5 towers. Max them out and spam more projectiles.
- Split your shots, bounce, multiply, shock, burn. The build is up to you.
- Your base can fly, towers and all. Explore the maps and mine ores.
- Research and craft mods. Just don't run out of energy.

WHAT IS IN THE GAME

- 41 towers, each with its own grid layout and function
- 33 mods, each with tiers, MK upgrades, a B-Side function, and 3 perks, for over a million tower builds
- 50 hand-crafted maps with three objectives each
- Endless mode after map 50, plus map-specific challenges
- A research tree, mod crafting, and a trader
- Spheres that scale into elites, bosses, armored, shielded, cloaked and flying
- Offline play, with cloud sync and leaderboards
- Cross platform: mobile and desktop

Comments on Sphere TD: Build & Mod Towers for Android

★★★★★ Cat · Apr 17, 2026

Good lil tower defense game with some nice customization when it comes to setting up the towers. Not faced a single advert yet, but it's coming to steam soon so will probably buy it there to support the dev.

★★★★★ Mgsgta3 · Apr 3, 2026

I want to start out by saying this game is exceptionally fun and challenging. While technically a tower defense game It's more about what you can come up with when building your towers (some towers have +50 mod slots and the different outcomes are pretty drastic(in a good way) only thing is that some of the crazier stuff doesn't seem to last too long before getting nerfed, and the crazy stuff is part of the fun, so I'd really like to see a "fun/unranked" mode with less punishing mods or similar.

★★★★★ ThatBad DisplayName · Jul 26, 2026

I used to believe infinitoid 2 was the only great complex tower game on the Google store platform, but this has changed my mind for the better. (I'm not saying one is better than the other, just that both are great tower defense games that I would recommend for those interested in the genre.)

★★☆☆☆ will wright · Mar 29, 2026

Was good but the latest patch completely nerfed early game into non-existence. Now you are effectively locked behind a paywall to even reach mid-game.

★☆☆☆☆ Alexander Wood · Jul 14, 2026

Broken. I couldn't place a turret. I couldn't get past tutorial prompt 2

★☆☆☆☆ Robert Mulcahy · Feb 9, 2026

I had no idea what was going on or what to do.

★☆☆☆☆ Spectre · Jun 13, 2026

Promising game that I could see myself getting into but saw lots of AI slop assets. If they can't make simple placeholder art then I know this game isn't worth my time
