Aviator licence vs custom build — which is cheaper?

Aviator's rev-share is high (typically 18–22%) but you get a brand players already know. A custom build pays back after roughly 6–9 months of steady traffic.

Can I add multiplayer chat and side-bets?

Yes — most crash APIs expose hooks for community chat, prediction side-bets and tournament leaderboards. We frequently bolt these on for operators.

Crash Game API Integration — Aviator, Spaceman & Custom Clones

How to integrate a crash game API in 2026: provably fair verification, WebSocket flow, bet/cashout endpoints, RTP tuning and white-label crash clones.

Crash games — Aviator, Spaceman, JetX, Crash X — generate disproportionately high GGR per active player. Integrating the API correctly is what separates a sticky crash lobby from one that bleeds players after week two.

Provider landscape

Spribe (Aviator) is the dominant licensable crash brand. Pragmatic Play (Spaceman), SmartSoft (JetX) and BGaming (Crash) compete on price and white-label flexibility. Each ships a REST + WebSocket dual API.

WebSocket flow

Once a player opens the game, your wallet must respond to bet, cashout and rollback events in under 200 ms. The WebSocket channel carries multiplier ticks 20–30 times per second — never block on DB writes inside the tick handler.

Open WS on game launch; maintain it for the whole session.
Authenticate every WS connection with a short-lived JWT.
Buffer bet acceptance separately from settlement to keep tick latency tight.

Provably fair verification

Surface the round's hashed server seed and revealed seed in the player UI. Provide a 'verify' button that recomputes the crash point client-side. Without this, your players will not trust the product — and trust is the only retention lever in crash.

White-label crash clones

If you want a branded clone, plan for 10–14 weeks of development: math model, provably fair plumbing, real-time game loop, admin panel, RTP tuner, anti-fraud and certification by an accredited lab (BMM, iTech Labs or GLI).
