I have been looking for a
small blackjack game. The limited storage space on my Venture (which runs 2.3.5) means I prefer my apps as small as possible. As well, small apps are likely to use less CPU power, also important on my device. As such, I compiled a list of sub-1MB blackjack apps sorted by size.
Why, you ask, am I babbling on about size? Well, a small app
probably has a good chance of being simple, not demanding much of the device. (Unless it is small because it depends heavily on the OS's libraries, but I was looking at ones that looked rudimentary, nothing with lots of features or nice graphics.)
Also you can look at the date on the app in the Play store. That's not to say that newer or larger apps won't run, but I'm guessing your chances are better with smaller, older ones.
You might have success with these ones that don't render properly on my tiny screen. I think yours is larger...

(That link goes to the last page of the search; scroll down and click "Previous" to go backwards through it seeing newer apps on each page.)
These from 2010 and 2011 are listed as incompatible with my device, maybe that means they're compatible with yours.
