$200 Craps Strategy: Probability, Payouts, and Expected Loss
Specific 2 or 12 · Forty $5 attempts · $50 parlay · 13.89% edge
The $200 craps strategy repeatedly bets $5 on one specific total—2 or 12—until it hits or the $200 is gone. After a hit, it parlays $50 on the same number for one roll. This is a high-volatility proposition plan, not a low-risk way to turn $200 into $1,500.
The headline outcome occurs about 1.88% of the time
At a 30-to-1 payout, a chosen 2 or 12 has a 13.89% house edge. Forty attempts create a 67.59% chance of at least one hit, but the strategy then requires the same one-combination total on the very next roll.
Exact rules used for this audit
- Choose either 2 or 12. Do not combine them.
- Bet $5 on that exact number for no more than 40 rolls, stopping when it wins.
- A win pays $150 profit plus return of the $5 stake at 30 to 1.
- Put $50 on the same number for the next roll only.
- If the parlay wins, it pays $1,500 profit plus return of $50. If it loses, stop.
Probability of each milestone
| Milestone | Probability | Approximately |
|---|---|---|
| Chosen number hits at least once within 40 attempts | 1 − (35/36)40 = 67.59% | About 2 in 3 sessions |
| First-stage hit, then same number immediately | 67.59% × 1/36 = 1.878% | About 1 in 53 |
| First-stage hit, then two immediate repeats | 67.59% × 1/36² = 0.0522% | About 1 in 1,917 |
“Once in 36” is a long-run average, not a deadline. The chance of missing the chosen number on all 40 attempts is still 32.41%, which loses the full $200 before any parlay.
Expected cost of the stated plan
Under a 30-to-1 payout and the exact stop rules above, the expected final bankroll is approximately $178.41. The expected loss is therefore about $21.59 per $200 attempt. That calculation includes the possibility of finding the first hit early, late, or not at all and the one-roll $50 parlay.
If the table pays only 29 to 1 “for 1,” or if its proposition maximum prevents the parlay, the result changes. Read the paytable before starting.
Why the original sales pitch failed
- A 32.41% complete-loss chance is not minimal risk.
- Hitting once does not make the next identical total more likely.
- A large possible payout does not imply positive expected value.
- A third press to $500 magnifies both table-limit and bankroll risk.
- The casino does not need a low proposition maximum to avoid bankruptcy; the payout already contains a large edge.
