Sin City Strategy
罪恶都市
Swing 4/5, win frequency 1/5
Suggested play: Either, depends what you want
Finishes ahead more often (about 6 in 10), but runs longer and loses more over time
Sin City has a win frequency of 1/5 and a swing of 4/5.
Every number here was measured on the real game engine.
Swing sits in the middle, so the two plans are close. Go by what you want:
finish ahead often → flat betting; lose less overall → Martingale.
What this page gives you is a clear view of the trade you are making: how often you win against how much you win.
How the play is decided
Swing 4/5. Our rule: swing 1–2 favours Martingale, 3–4 works either way, 5 favours flat betting, the higher the swing, the smaller the edge doubling gives you. Across every game here the rule holds 91% of the time.
A swing of 4/5 sits in the middle band, where the two plans measure close together.
Forcing an answer here would not be honest.
Pick by what you want: finishing ahead often, or losing less.
Swing is not good or bad, it describes rhythm: the higher it is, the more the big wins bunch into a few spins and the quieter the rest. A denser win frequency means small returns arrive more often, so you last longer through the dry stretches.
The two plans, measured side by side
Same game, same bankroll and same stops (1000 to start, 3 per spin, stop at +10%, stop-loss at −30%). The only difference is whether you raise the stake after a loss. The stopping rules must match or the win rates cannot be compared, that is where most strategy sites go wrong.
| Martingale | Flat betting | |
|---|---|---|
| Sessions ending ahead | 44% | 65% |
| When you win | +39% | +14% |
| When you lose | −32% | −30% |
| Average loss per session | 10 | 15 |
| Spins per session | 19 | 147 |
Flat betting finishes ahead more often (65% vs 44%),
but it loses 5 more per session on average (flat 15, Martingale 10, on a bankroll of 1000).
Want to win often? Flat. Want to lose less? Martingale.
- Want to lose less overall and win big when you win → Martingale
- Want to finish ahead often and play longer → flat betting
How to play it (using the demo 1000)
Martingale
↻ Back to 'play 5 spins'. It settles in about 19 spins on average
Flat betting
- Start with 1000 and a base bet of 3 (0.3% of the bankroll).
- Never change the stake, not even after a loss.
- Up 10% → take it and stop.
- Down 30% → stop the loss and leave. Expect around 147 spins; patience is part of the plan.
↑ Every number measured on the real game engine over tens of thousands of sessions.
A Martingale session settles in about 19 spins; flat betting takes 147.
The house edge is charged against everything you stake, so less time exposed means less erosion, which is why Martingale wins less often yet loses less per session.
A high win rate is not profit, read this part
Flat betting finishes ahead more often (65% vs 44%),
but it loses 15 per session on average, against Martingale's 10 (on a bankroll of 1000).
That is because flat runs 147 spins, and the house edge is charged on total stake.
The two plans trade how often you win against how much you win.
Neither turns the expectation positive.
Anyone promising you a staking plan that profits is lying to you.

Common questions
Can I play Sin City for free?
Yes, no signup, no deposit. Use the demo credits above to learn its rhythm and how the free games trigger.
Should I use Martingale or flat betting on Sin City?
It depends what you want: flat betting finishes ahead more often (65% measured), while Martingale wins less often (44%) but takes home +39% when it does. At swing 4/5, our pick is Either, depends what you want.
Is Sin City suitable for beginners?
Win frequency 1/5, swing 4/5. Keep bets small (0.3%) and hold the stop-loss. Higher swing means longer dry spells, demanding more patience and more bankroll.
Does Martingale make money in the long run?
No. It reshapes wins and losses, fewer wins, bigger ones, less time exposed, but expectation stays negative. A deep bankroll buys survival through dry spells, not a guaranteed win.
