Xiangqi: Chinese chess, duel

Xiangqi: Chinese chess, duel brings one of the world's oldest and most widely played strategy games online, built around a board split down the middle by a river that shapes almost every tactical decision you'll make. Pieces here don't map directly onto Western chess equivalents — the general is confined to a small palace, cannons need a piece to jump over before they can capture, and soldiers gain new movement options only after crossing the river. Because the pieces and their constraints are genuinely different from standard chess, existing chess experience helps less than you'd expect; Xiangqi rewards learning its own specific piece interactions from scratch. It's a rewarding pick if you're looking to expand beyond Western chess variants into a strategy game with centuries of its own theory behind it, and it's free to play directly in the browser with no download required.
