I want to create an android application for BlackJack. First of all i want to ask is 8-deck game beatable? Is there any way to be sure that online casino will not cheat you (Play fair and not cheat behind the live cam)? If these answers are positive i want to ask some things which are important for my app.

1) Which count systems should i use. For now i am thinking Hi-Lo, Rapc, Zen and 7red. Which are the top systems in our days (difficulty level doesn't make any difference in application. Don't consider difficulty as negative factor.)?
2) I want to add four levels of betting spread (prudent, normal, risky, too risky) . Are there any resources where i can find how should i spread the bets and which will be the advantage for each accordingly?
3) Which should be the wager for the player based on his bets and spread?
4) Is there any site where i can find the player advantage for the casino rules, spread, counting system, bet amount in order to make the best combination of them?

I have bought The world's greatest blackjack book and i have read a lot of articles about counting systems and spread. The problem is that i can't find the four best counting systems in our days (the difficulty of them doesn't matter due to the application will do all the difficult thing for you).

If i have forgotten any important factor in order to beat BJ please inform me (I have take into account basic strategy for my app).
