Idle Defense Grid is a minimalist strategy game that combines classic tower defense mechanics with idle progression. Place towers on a small grid, defend your base from incoming enemy waves, and earn resources over time to strengthen your defenses. Every decision matters, as limited space forces you to think carefully about positioning and upgrades. With clean visuals, smooth gameplay, and gradually increasing difficulty, Idle Defense Grid offers a relaxed yet strategic experience. Easy to understand but challenging to master, the game rewards smart planning and long-term thinking.
