Remember those old Flash games that just felt like the shows they were based on? This one’s a classic—you play as Katara, clearing out thick smog from the Earth Kingdom while Aang and the gang track down war machines hidden in the pollution. It’s simple but weirdly satisfying: you sweep your mouse around to reveal patches of clean sky, and whenever you uncover a machine, the rest of Team Avatar jumps in to wreck it.

The smog spreads back if you’re too slow, so there’s this nice little tension between clearing space and hunting for machines. And yeah, the graphics are definitely early 2000s Flash, but there’s charm in how the characters move exactly like they do in the show. If you’ve got nostalgia for Avatar or just miss that era of browser games, this one’s a solid time-waster.
