Made me an expert!
I just have the tutor warn me when I make big mistakes. Errors of less than 0.1 are too subtle for me to understand. I can get to 21 before the computer more often than not if I really concentrate. This will teach you when to double and when to decline. After practicing with this, I was able to win a match to 21 against my friend from MIT who got by one summer in Paris just by playing backgammon.
I like peeking at the expected outcome move to move. Towards the end, when there are fewer pieces, I can calculate this value in my head.
The board fills the screen when turned on its side. Lock the orientation that way when you start. It is easier to tap on the pips when they are bigger. A typical move takes four taps: one to roll, two to move, and one to tell the computer to move. Select the tap to move setting to have it behave that way.
I have been enjoying Toms app from its earliest versions where you could keep on doubling beyond a billion and move the second piece while the first piece was still moving. His web site is filled with decades of backgammon articles and forum archives. Backgammon is his passion and you can feel that when you play his game.
