Long backgammon that teaches you to play better
Free, no ads. Play the computer, a friend across the table, or someone in another country — and after the game find out exactly where your chances went.
Computer at three levels
From easy, which plays a simple race, to hard, which looks two moves ahead at your replies. A live win-percentage sits right on the player cards.
Game analysis
After the game, a review of every move: best versus played, mistakes measured in lost win percentage, and a win-probability curve you can scrub to any moment.
Academy
Mistakes from your own games grouped by tactical concept — stacking, a broken wall, a greedy bear-off. Each one can be replayed yourself in the trainer.
Online with friends
A room by code or link — send it in any messenger and your friend joins the game with no signup. A dropped connection does not kill the game: there is time to come back.
Nearby play, no internet
Two phones side by side connect directly over Wi-Fi or a hotspot: swap QR codes and play. Works on the road and through a blackout.
Scheduled challenges
Agree on a time: your opponent confirms or proposes another, the event lands in a calendar with a reminder, and the room is already reserved. A no-show is a walkover.
Two-player tournaments
Fixed-length or open-ended series with a points table and multipliers for Mars and Koks. A game played on a physical board can be entered into the standings too.
Statistics and replays
Game history with step-by-step replay, dice-roll distribution, winning streaks, achievements and an activity grid — like GitHub’s, only about backgammon.
Works like an app
Installs to your phone from the browser (PWA) and opens without internet: games against the computer or two players on one screen run fully offline.
Fair dice
Rolls come from a cryptographic random number generator (Web Crypto CSPRNG) with no bias. You can check the distribution of your own rolls in your statistics.
Which of these needs an account?
Playing the computer, two players on one device, nearby play, and joining a room by invitation all work without signing up. An account (Google or email) is needed to create online rooms, send scheduled challenges, run tournaments, and sync your statistics across devices.
Don’t know the rules? Not a problem
The app highlights only legal moves, and the complete rules of long backgammon are always one tap away.
