Crash games API integration: what changes compared with slots
Crash and instant games arrive through the same casino API as slots, but they behave differently once they are live. Rounds are shared by many players, bets and cash-outs arrive seconds apart, and one round can settle hundreds of wallets at once. This is what to plan and test before you put them in the lobby.
The short version
- One round, many players: plan wallet capacity for bursts when a round ends.
- Bet and win are separate calls, often seconds apart; never assume they arrive together.
- Auto cash-out and two bets per round are common features; test both.
- Rollbacks matter more: a dropped connection mid-round must still settle cleanly.
- Give support round history; players ask for it.
How a crash round flows
A betting window opens and players place bets. The round starts and a multiplier climbs. Each player cashes out when they choose, or automatically at a target they set. At a random point the round crashes, and every bet not yet cashed out loses.
In wallet terms that is a debit when the bet is placed and a credit when the player cashes out. A losing bet may get no further call, or a zero-value result that closes the round; it depends on the provider, so read their spec for how a round is closed.
Why the load looks different
A slot produces one player’s calls at a steady pace. A crash round produces many players’ debits in the betting window, then a wave of credits as they cash out, then the settlement of everything left at the crash. Wallet latency that is fine for slots can cause timeouts here, and timeouts cause retries. That is why idempotent wallet calls, covered in our integration checklist, matter even more for this category.
| Aspect | Slots | Crash and instant |
|---|---|---|
| Round | One player | Shared by many players |
| Bet to result | Moments apart | Seconds apart; the player decides |
| Wallet load | Steady | Bursts when a round ends |
| Cash-out | Not applicable | Manual or automatic |
| Disputes | Replay of the spin | Round history and the multiplier at cash-out |
Features to test before launch
- Auto cash-out at a target multiplier, including when the player has closed the tab.
- Two bets in one round, cashed out at different moments. Spribe’s Aviator, one of the best-known titles in the category, offers two bet panels.
- Free bets or free rounds if you plan promotions, and how their wins are tagged.
- Round verification: many crash titles publish provably fair checks; make sure support knows where players find them.
Where crash fits in your catalogue
Crash and instant games suit short sessions and sit well next to a sportsbook. Through a casino games API they sit in the same catalogue as slots and live casino, so you add the category without a separate integration. Studio profiles such as Spribe list the titles, and our crash games guide covers the format itself.
