Strategy Defense 6

Strategy Defense 6 was one of those games you'd find in the later years of the Flash era. It fit right in with the straightforward, single-screen defense titles that were common then. You'd load it up in your browser, and it was ready to go without any fuss.

You control a static defense position, using your mouse to place units and structures along a set path. The main objective is to stop waves of enemies from reaching your palace on the right side of the screen. You spend resources to build mines and turrets, then upgrade them between rounds to handle stronger opponents. The pacing is steady, with each wave giving you a moment to adjust your layout before the next rush begins. It feels like a focused puzzle, where a single misplaced unit can unravel your entire line.
