PolyGun: Idle TD

Drop turrets, stack upgrades, and watch waves of neon polygons shatter under your automated firepower.

PolyGun: Idle TD is one of those games that tricks you into thinking you'll just place a few turrets and then suddenly you've forgotten to eat lunch. The core loop is simple: enemies roll in from the sides, you click or tap to drop defensive guns, and they fire automatically. It starts out gentle, a couple of slow-moving triangles, but before long the screen is filled with lasers, rockets, and enough polygon fragments to make a geometry teacher weep. What really hooked me is the idle progression. You earn cash per kill, and that cash buys new turret types or flat damage upgrades. There's a subtle rhythm to when you should save for a big unlock versus spreading smaller upgrades across existing towers. I left the game running for twenty minutes once and came back to a boss getting shredded by a wall of fully upgraded cannons that I didn't even remember placing. That's the kind of satisfaction an idle TD should deliver. It's not overly complex, and that's the point. One finger or mouse click handles everything, making it a perfect tab-back-and-forth game while doing homework or pretending to listen in meetings. The polygon aesthetic is clean, the explosions feel crunchy, and the difficulty ramps just enough to keep you tinkering with placement and upgrade order. If you enjoy games where the numbers go up without requiring constant attention, this one will eat an afternoon before you realize it.

Mouse click or tap to play

Place a few cheap turrets near the middle so they cover multiple paths early on Don't upgrade every turret equally — focus on two or three high-damage spots Save for the rocket turret as soon as you can, it clears groups faster than anything else Let the game idle for a few minutes after a big upgrade and come back to a pile of cash Rebuild from scratch after each wave clears; positioning matters more than raw level Watch the boss path before it spawns and shift your best turrets to that lane
