Checkr

Checkr is a clean, modern chess game you can play right in your browser or on any other device. No accounts, no clutter, no interruptions. Just open the app and play.

Whether you want to sharpen your skills against the computer or challenge a friend, Checkr has you covered. Play chess against an AI opponent with three difficulty levels — easy for casual games, medium for a fair challenge, or hard when you're ready to be tested. Switch between difficulties anytime and improve at your own pace.

Want to play chess with a friend? Checkr offers same-device multiplayer so you can pass the phone back and forth for a quick game anywhere. If you're on the same wifi network, connect over your local network for a seamless experience — no internet required. And when your opponent isn't in the same room, take your game online and play chess with anyone, anywhere, on any device (crossplay supported for Android, macOS, Windows, Web).

Checkr is built around a simple idea: a chess app should respect your time and your privacy. There are no ads, no data collection, and no tracking. Your games stay on your device. Nothing gets shared, nothing gets sold.

Checkr is perfect for anyone who loves chess but is tired of bloated apps full of pop-ups and paywalls. Whether you're a beginner learning the game or an experienced player looking for a clean place to play, Checkr keeps the focus on what matters — the game.
