lichess

Free, powerful chess with zero ads and endless variation

lichess is a dream come true for chess enthusiasts who want a complete, distraction-free experience. Entirely free, open source, and free of ads, it focuses purely on the game itself and delivers an astonishing amount of depth.

You can play virtually any format you like: bullet, blitz, classical, and correspondence, either in casual games or in fast-paced arena tournaments against a huge pool of opponents. Matchmaking is quick and generally fair, and you can easily find, follow, and challenge friends or favorite players. Statistics are detailed, helping you track rating progress, time controls, and performance by opening.

Where lichess really shines is in its training and analysis tools. You get endless puzzles that adapt to your strength, powerful computer analysis with clear annotations, and both opening and endgame explorers that go far beyond what most free chess services offer. Variants such as Crazyhouse, Chess960, King of the Hill, Atomic, Horde, and more dramatically change the feel of the game and keep things fresh, whether you are online or offline.

Offline features are unusually rich: you can play against the built-in engine, use Over The Board mode to replace a physical set, turn your device into a dedicated chess clock, or edit custom positions for study.

The interface is clean and functional, with multiple board themes and piece sets, and it adapts well to both phones and tablets, including landscape mode. However, the design favors efficiency over flash; players looking for 3D boards or animated characters may find it visually plain. Newcomers might also feel slightly overwhelmed by the sheer number of options at first.

Still, for serious players and improving beginners alike, lichess offers one of the most complete and generous chess experiences available.
