Official public preview
Mercyless for Android.
Join the same private rooms as browser players through a native, safe-area-aware landscape interface. The Android app uses the same server, deck, rules, reconnect protection, and rematch system as the website.
Temporary preview: the current Expo download is expected to expire on August 13, 2026. If it has expired, do not download a copy from an unrelated mirror; return here for the next official build.
Included in the Android app
- Real-time cross-play with browser players in the same 2–10 seat private rooms.
- Host-added bots, player removal controls, persistent rematches, and 100-second reconnect recovery.
- The complete server-enforced rules: voluntary drawing, stacking, 7 swaps, 0 passes, power cards, UNO, and 25-card elimination.
- Landscape-safe spacing for notification areas, display cutouts, gesture bars, and Android navigation controls.
- A larger direction indicator, current-colour marker, adaptive card hands, danger states, reactions, sounds, and haptic feedback.
- A native rules guide and private feedback form. Resend credentials and the destination email stay on the server and are never stored in the APK.
