In this post, we will take a look at an Android app that we at Deluxe Backgammon have been using for quite some time. Backgammon Free (by AI Factory) is an app for mobile devices that allows you to play backgammon anywhere. There is a single-player mode where you can match yourself against the CPU or a two-player mode that allows you to play against another person. There is no online play and an internet connection is not required once the game is installed. At the time of writing it is the highest rated (4.4) offline backgammon application in the Google Play store.
The game is free to download and contains in-game advertisements. The ads are fairly unobtrusive, just a small window on the top left corner of the screen. There is also a brief full-screen ad between games. Turning off WiFi during play disables the ads. There are no in-app purchases. The game has an easy to use interface and the graphics are colourful and sharp.
The CPU offers 5 levels of difficulty. The first couple of levels are, as expected, really only suitable for beginners. The higher levels are challenging for intermediate players. Advanced players would probably not be too challenged even at the highest level. Some of the CPU’s moves, even at the highest level, are surprising. For example, an opening 3-2 move to 13/8. Our research suggests this is one of the weaker opening moves, but it regularly makes this move on level 5. We don’t think this application is pretending to be a replacement for some of the commercially available PC programs. It’s an honest, portable and fun way to play backgammon on the move.
September 2021 – Two extra levels have been added with improved AI, there has been no change to the original 5 levels. Will add further comments after sufficient time to review levels 6 and 7.
The CPU strategy is Gaming Labs Certified, which means this program rolls genuinely random dice. It will frustrate you at times as it seemingly makes the exact string of rolls that it needs to hit and re-enter. This is not evidence of cheating, rather evidence of good backgammon play. A good backgammon strategy is all about maximising the probabilities to fall in your favour. This is what the CPU is doing, it makes moves designed to maximise the chance of good rolls for itself and minimise the likelihood of good rolls for its opponent. There is also a manual roll option, so you can roll real-world dice and enter the numbers into the application.
The Auto Bear Off option allows you to give the CPU control of your moves. We used this a couple of times, when we fell behind in the race, but didn’t really want to quit the game. It is not worth using as it is probably the only flawed feature of this game. It frequently left checkers behind so that you would lose by a gammon or worse. A human would never make this fundamental error.
There is a helper option, which will suggest a move if you really don’t know what to do. It simply highlights the checker and the corresponding point the CPU suggests moving to. There is no explanation, but that is fine as this is an app not meant to be a high-end analytical tool. There is an option, which is turned on by default, which highlights the legal moves available to the selected checker. This is really useful for absolute beginners.
Backgammon Free is surprisingly configurable. There are a host of preferences that can be set in the Options menu. These include, but are not limited to, board and checker colour, pip count display and direction of play. You can also hide various features such as the Undo button and Helper prompts. We advise keeping the Undo option. Because it is a touch screen application if you inadvertently touch the wrong point the CPU accepts the move and automatically starts the next roll. In real life, your move is still reversible until you pick up the dice.
Backgammon Free keeps statistics for each level of play, including matches won, doubles rolled, total dice rolls and opening rolls won. This is useful in tracking the improvement in your play over time. There is also a complete explanation of the rules of backgammon within the app.
This is a great app. We at Deluxe Backgammon have played thousands of games on Backgammon Free by AI Factory. It allows you to play backgammon on the move against a human or the CPU. It probably won’t help you get your game beyond an intermediate level, but for a free app, you can’t really ask for more. Deluxe Backgammon highly recommends Backgammon Free.
Note: After applying the principles from the Deluxe Backgammon Playing Guides our win rate at level 5 improved from 46.55% to 50.31%. This was comparing the first one thousand games vs the second thousand.
20/05/2020 – the win rate has improved to 60.03% at level 5 after an additional two thousand games.
November 2021 – two new difficulty levels have been added (6 & 7). I still have a win rate of 60% on level 7 after 500 games. I don’t notice much difference between levels 5 and 7. Backgammon Free by AI Factory is still the best free app out there.
