Would like to help. Can't download it. Can you make it easier to download on a computer?

Great thanks! Hm it's only for Android devices at the moment but here's a web version you can try:

Thanks. I saw many problems:

1. When I changed the rules settings, the BS chart didn't adjust. It remained the same as for the default setting.

2. There were many mistakes in the BS. You need to either go online to the Basic Strategy Engine at blackjackinfo.com or look at the BS charts in BJA3.
For example, with DAS, 4-4 should be split vs. 5-6.
A,6 should surely not be doubled vs. Ace!
16 should be surrendered vs. Ace.
If S17, A,8 shouldn't be doubled vs. 6, nor A,7 vs. 2.

I'm sure there are others. I stopped looking.

3. As for the interface, make the dealer's upcard the entire card! Don't hide it under the hole card, which, logically, goes BELOW the dealer's upcard, not on top of it. Also, make all the cards larger and easier to read quickly.

Fix all these things and then let me look at it again.

Ok, we've cleaned up a lot of the logic:

You might need to do a hard refresh (or open it in incognito window) to see the latest version. The interface might be slightly off on desktop but it looks much better on mobile

Everything looked great except when I went to play a hand in practice. There were no choices below for the decision, just the cards on the screen.

Ok try again now

 

[DSchles]

Better! New problem: I switched on late surrender. There is no choice for "first two cards only," as opposed to "any number of cards" (which is very rare and probably not worth programming).

So, I had 2,8 vs. dealer's Ten. I hit and got a 6, for 16. So, I hit again (even though multi-card strategy for 16 vs. T is to stand. I knew you wouldn't have programmed that.) Anyway, it told me I was wrong and that I should have surrendered! Er, sorry, no can do! So, that has to be fixed.

Sorry, one more problem. Just got 15 vs. T. There is no choice in the blue boxes below for surrender. So, you have to reprogram so that when surrender is chosen for the BS chart, you offer that as an option for all potential surrenders (not just the right ones!).
