Checkers

An Android checkers game made by jnetai.com.

Modes

• Play vs AI — offline computer opponent (Easy / Medium / Hard)
• 2 Player — pass & play on one device, offline
• Online Multiplayer — peer-to-peer over the internet (WebRTC via public Google STUN + openrelay TURN):
  • Host a game — share the code or QR with an opponent
  • Join a game — enter or scan the code
  • Quick Match — random matchmaking: first looks for an existing host, otherwise auto-hosts a room, looping until a player is found

Settings

• AI difficulty
• Worldwide rules: UK / Europe (default), US / American, International
• Per-player timer (off / 3 / 5 / 10 minutes)

High Scores

Beat the AI to earn a score — fewer moves and a faster time rank higher.

Build

Releases are built with GitHub Actions on a tagged push (v*). Never build locally.

git tag v1.0.0 && git push origin master --tags

The release workflow signs the APK with a stable per-app keystore so in-place updates never require uninstalling the previous version.
