Summary: fun money games against an intermediate AI on four levels
I was looking forward to playing “The Backgammon”. After all, it’s by UNBALANCE, the company that created “Crazy Stone Go”, which was the best Go-playing app for Android/iOS before the AlphaGo clones came. I’m still playing most of my Go games with UNBALANCE’s nice app, and so I expected a lot from a backgammon of these developers.
To some extent I was not disappointed. “The Backgammon” is a solid implementation of Backgammon; unlike many of its competitors it features money games and matches up to 15 points, correctly implements everything including the Crawford rule, allows to try out different moves before committing to one etc.
I like “The Backgammon”’s presentation. Two different nice boards wait for you, nicely rendered on phone and tablet. The menu system is easy to understand and has a clean, professional look.
The app offers both online playing (which I haven’t tried – there’s backgammon galaxy and backgammon heroes with strong analysis features) and playing against an AI. This AI offers five difficulty levels from “gruesome gruesome beginner” to “beginner”.
I must confess I’m disappointed by UNBALANCE’s effort to build a Backgammon AI. Other than their Go this is no master. Even on its hardest level 5 it makes obvious beginner mistakes, like doubling with a checker behind a 6-prime, just because it’s 10 pips ahead in the race. Also its checker play is doubtful at times. I haven’t fed a match into XG, but I am very convinced it plays not better than a PR of 20 or so. Here’s a few examples:
In the example above, black has a checker on the bar, behind a 5 prime, and has nothing. But because I’m only 9 pips ahead in the race, it accepts my double.
In this situation, the AI has one checker trapped behind a six prime. It’s ahead in the race, but in the next moves, its home board will crash, I will move forward my prime. I guess black has less than 10% winning chance. But it’s ahead and doubles.
To increase longevity and give you a challenge, “The Backgammon” includes a nice “challenge mode”, in which you have to beat every level at 5 different match lengths to earn medals. Unfortunately, though, Level 1 is so incredibly weak that I can’t get myself to try out what happens if I win all medals (it leaves direct shots without any reason).
So, if you’re an intermediate player or better, you probably won’t find an opponent that can offer you exciting matches here. But for beginners, this is an acceptable Backgammon that you can have a great time with, for free. “The Backgammon” is purely ad-financed. It shows you ads on the top of the screen, and will show you an ad movie after each match. There’s no in-app purchase to get rid of the ads.
Please note, though, that an app playing on this level cannot teach you to become a better player. Not because there is no tutor mode, and also not because it just doesn’t play well enough to be a good teacher. For this you need e.g. XG mobile, True Backgammon, Backgammon NJ.
