Oscar's Grind:

Oscar's Grind may be the ultimate in maximizing the number of small wins in relation to the large losses. The originator, only known as Oscar was a craps player who told reporters he gambled a lot and had never had a losing trip. This is not inconceivable. According to Tom Ainsley (and much of this discussion has come from Mr. Ainslie's "How to Gamble in a Casino") Julian Braun's computer studies showed the probabilities a house limit when the limit was 500 times the smallest allowable bet would only be once in 4,250 sessions. Braun's calculations also showed that bucking a $1.00 to $500.00 house limit, the average loss (because the progression would reach the house limit) would be over $13,000.00.

So here is Oscar:

Rule 1: The goal is to win one unit at the end of each progression and, whatever larger bet might be dictated by the other betting rules, will be dropped to a bet just large enough to gain one unit. This rule overrides.

Rule 2: Bet 1 is one unit.

Rule 3: If Bet 1 is lost, Bet 2 is one unit.

Rule 4. After a loss, the bet is the same as the bet just lost.

Rule 5 After a win, the bet is one more than the bet just won.

Example: First four bets are lost, player is down 4.
Next Bet (1 because it is the same as the bet just lost, Rule 4) won.
Next bet 2, Rule 5. Player down 3. Lose. Player down 5.
Next bet 2, Rule 4. Win. Player down 3.
Next bet 3, Rule 5. Win. Player even.
Next bet 1, Rule 1 overriding Rule 5 which would say bet 4.
