Correspondence Chess

You make a move, close the tab, and come back tomorrow. That's the rhythm of Correspondence Chess — a slow-burn, turn-based take on the classic game where matches unfold over hours or days rather than a single sitting. Challenge real opponents online, test yourself against an AI, and track your progress through an ELO rating system with a global leaderboard to climb.

What sets it apart is the depth behind each game. With over 3,600 openings catalogued, there's genuine room to study, experiment, and build a repertoire rather than just reacting on instinct. It's the kind of strategy game that rewards patience — every position has time to breathe, and you can actually think before committing. If you prefer a faster, offline alternative, Chess offers a focused single-player experience against an AI at three difficulty levels.

Works best on desktop where the board has room to stretch, though it plays cleanly on mobile too — ideal for squeezing in a move between tasks.
