To sum it up...

[Gizmotron]

1. Know how to read randomness.
2. Find out what is going on in the strongest form.
3. Get actual data on the current effectiveness state.
4. Only place a bet while currently in the winning state.
  a. any loss is proof that you are not in the winning state any longer.
5. Use large enough bets that two or three net wins over any losses is enough.
6. Leave the casino with your success.

It takes experience with every step.
It comes down to being in a win streak to place bets, and to quit while you are ahead.
