PolyGun: Idle TD

PolyGun: Idle TD puts you in control of a turret that fires on its own — but don't mistake that for a hands-off experience. Waves of geometric shapes pour in from all directions, each type moving differently, some faster, some tankier, some arriving in swarms that overwhelm underprepared defenses.

Between waves, the real decisions happen. Cards unlock new abilities, upgrades boost damage and fire rate, and quests push you toward goals you might not have set for yourself. The idle element means progress continues even when you step away, though active play rewards attention.

Daily challenges and reward systems give returning players something fresh to work toward. The difficulty ramps steadily without becoming punishing too early, making it a decent pick for anyone who enjoys watching a well-tuned defense hold the line against mounting chaos.
