What’s new
Everything that changed in the game: new features, improvements and fixes. The latest on top, earlier months in the archive below.

Play long backgammon against your own ChatGPT, Claude or Grok
There is a new "Your agent" item on the home screen. Create a game, copy the code and give it to your assistant in a chat: it connects to ProNardy and takes the seat opposite you. The agent does not compose moves itself, it picks one from the list of legal moves, so there is no hitting, no bar and none of the other short-backgammon rules. ProNardy rolls the dice, and the agent cannot see them in advance.
After each move the agent can briefly explain why it played that way. If it goes quiet for a long time, the game is paused and you can end it without a result. Any finished game of yours can be handed to the agent for review from your history: it gets the engine evaluation of every move and walks you through the key moments. Games with an agent stay in your history but do not count towards your statistics or achievements. An account is required.
The computer plays the position instead of just racing
The computer used to play almost every game as a racer: it ran home and never built walls, because it treated a point as blocked only with two checkers, as in short backgammon. Now a single checker already blocks a point for it, and it values leaving the head, a barrier in front of your head and freedom to move. Once there is no more contact, it simply races home. Over 400 test games the new Hard beat the old one 90 times out of 100.
All three levels now share one way of thinking and differ only in search depth and randomness: Easy sometimes picks a weaker move, Medium looks one move ahead, and Hard also works out your reply. The best-move hint uses the same evaluation, so it teaches the style the computer actually plays.
The board no longer freezes while the computer thinks
On Hard the computer looks two moves ahead, and in tangled positions that took several seconds. During that time the board ignored your taps, because the calculation ran in the same place as the interface.
The computer now thinks separately, in the background, and the board stays responsive. If you leave the game in the middle of its thinking, the calculation simply stops.
Game history: real duration, resignations and deleting a game
Game duration now counts only active play. Breaks longer than three minutes are shown separately as idle time, so a game left overnight no longer looks twenty hours long, and the average duration in your statistics is honest.
Resignations and time losses are labelled in your history: points are still scored from the position, but you can now see the game was not played to the end. You can also delete a single game from your statistics with the ✕ button and a confirmation: it disappears both on this device and in your account.

Board points are numbered 1 to 24
The board labelled points 1 to 6 in every quarter, while the Coach and the game review speak in continuous numbers from your head: 24 is the head and 1 is the last point before bearing off. So a hint like "22 to 18" pointed at a number that was nowhere on the board.
Points are now numbered 1 to 24 from your side in any board orientation, so the number from a hint can be found at a glance.
The home screen appears at once and does not jump
On a slow connection the home screen used to stay empty for a while, and when the menu finally appeared everything below it slid down. The menu is now visible from the very first frame, before the app has fully loaded, and nothing shifts.
During a game the site footer is gone entirely: the board takes the whole screen.
An explanation and a way back instead of a blank screen
When something broke in the app, you used to get an empty page with no buttons at all, and only a reload helped. A failure now shows a clear message with a way back to the home screen, and we receive an error report so we can fix it.
A deeper guide and a new "Long vs short backgammon" page
The Rules and Tactics pages grew two to four times longer, with a scoring table, worked examples and answers to common questions. A new page explains how long backgammon differs from short backgammon, with a comparison table. Everything is in Ukrainian and English.
Game review on desktop: the board is visible again
Turning on "Analysis" in game review used to grow the panel downwards and squeeze the board until it was tiny — and clicking a specific mistake made it disappear altogether. The screen broke exactly when you started using it.
On desktop and tablet the review now sits in its own column on the right, while the board takes the full height on the left and keeps its size no matter how many hints the analysis shows. A long list of mistakes scrolls inside the panel. The panel itself no longer jitters during playback either: the verdict on each move appears in the space reserved for it, and the chances curve and the list of mistakes stay put. On phones nothing changes.
A game no longer ends in silence
When a game finished, the outcome used to appear as a small line off to the side — and unless you knew where to look, it was not clear how exactly it ended. Now the last move opens a summary: who won, by what score — oin, mars, koks or home mars — how many points that is, and why the score is what it is.
You can dismiss it whenever you like: the final position stays on the board, so you can take your time working out how it all played out. If the game unlocked a new achievement, it appears right there — previously you would only find out by opening your profile.
A new home screen
Instead of twelve identical buttons in a column, "Play online" is now a large card at the top, followed by playing on this device and playing nearby, with separate "Compete" and "My account" groups below. Names are short with an explanation underneath, and emoji have been replaced by our own icons: the same screen used to look different on iPhone, Android and Windows, because the operating system drew those symbols.
Admin has been removed from the home screen — it is not a game mode, and it moved to the profile where the people who use it already are.
Mars and koks achievements now need an actual win
The "First mars", "First koks" and "Home mars" achievements promise you WIN a game by that score. In fact they counted any game that ended that way — so they also unlocked when you were the one who lost by it. "Three in a row" in games against the computer could likewise credit you with the computer’s streak.
This is now fixed. As a result a badge earned under the old rule may disappear — sorry, that stings. But an award for losing devalues it for everyone who earned it honestly. Win by mars or koks and the achievement comes straight back, this time for good.
A new "Weave" board and smaller improvements
Board appearance has a new theme, "Weave": a woven field and a frame with visible grain. Until now every theme was flat fills and gradients — the board can have texture.
Along with it: input fields finally look like part of the app rather than white browser rectangles; buttons are now big enough not to miss with a finger; keyboard navigation shows where you are; and if your system asks for reduced motion, the move highlight no longer pulses.

The installed app no longer stays sideways
ProNardy added to your home screen used to force landscape EVERYWHERE — menus, statistics and the Academy included, even though they read better top to bottom. The app now follows your phone, exactly like the site in a browser.
Landscape is only needed for the game itself: the long backgammon board is wide, so game screens still ask you to turn the phone. If the app is already on your home screen, it may take a while to pick the change up — Android refreshes installed apps within a day; on iPhone it is quicker to add the shortcut again.
The Academy no longer makes you wait
A game review is now computed once and stored on your device. Before, every visit to the Academy started the analysis from scratch — even if you had just waited it out.
A new game is reviewed in the background right after it ends, so everything is ready by the time you open the Academy. Older games catch up in a queue, and leaving mid-queue is safe: what is done stays done.
Your game history can be saved to a file
The statistics screen now has a “History archive”: save your games to a file and restore them on a new phone or after clearing your browser.
The file carries your profile too, so online games stay yours: the Academy reviews your side, and the replay board faces the right way. Importing only adds games — a file can never erase the history you already have.
The Coach explains moves in plain words
The replay and the Academy trainer now have a Coach: it puts what the engine computed into plain language and answers follow-ups like “what if I had played this instead?”.
The Coach runs on your own AI provider key. The key is stored on your device only — our server never sees it. Without a key everything works exactly as before.
The computer got stronger on Medium
The engine now sees structural gaps in its own home board and stops leaving them for a small gain in tempo. Measured over thousands of games that is worth about four percentage points of win rate — noticeable if you play on Medium.
English interface
ProNardy now speaks two languages. The language is detected on your first visit and can be switched by hand at any time; a room link opens in the language of whoever you sent it to.

The Academy: a review of your recurring mistakes
After a game, every move is compared with the best one, and the Academy collects your mistakes across all games and groups them by concept — stacking, a broken prime, gaps in your home board.
A mistake is not just shown but replayable: the trainer opens that exact position and waits for your move.
Online play, nearby games and tournaments
Playing friends online by a room link arrived — your opponent needs no signup. Two phones side by side can play with no internet at all, over a direct connection.
Tournaments came too: a round-robin for any number of players, with a table and full game history.
ProNardy went live
The first version: the exact rules of long backgammon — the head rule with its first-move exception, the six-point prime, bearing off with overage, and the Oin / Mars / Koks / Home Mars scoring scale.
In the box from day one: two players on one device, a computer opponent, game history with statistics, and offline play once installed on your phone.
Got an idea? The app has a “Write to us” button — every message is read by the person who builds this game. What ProNardy can do today is in the feature overview.
