• Partner wallet integration
• Admin and reporting tools
• API + iframe integration

The complete source code is publicly available:


Feedback, suggestions, and contributions from the iGaming community are welcome.

Interesting project. The part I’d pay most attention to is the wallet and settlement layer rather than the games. We ran into similar issues when working with NuxGame integrations, where duplicate callbacks, interrupted rounds and balance reconciliation caused more headaches than the actual game logic.
The API + iframe approach also makes sense for testing individual games without rebuilding the whole casino frontend. Curious how you handle unfinished rounds and wallet reconciliation when a player disconnects midgame.

Appreciate this — wallet/settlement is exactly the layer we spent the most time on.

We call the operator wallet (debit/credit) with a deterministic requestId so retries don’t double-apply, and we write a pending local transaction before the partner call so a timeout is still reconcilable. Instant games settle in the same request; Mines keeps the round ACTIVE on disconnect and restores it on reconnect (no auto-cash-out). If debit/settle/credit fails after the round exists, we mark it FAILED with a stage and reconcile against the operator by requestId rather than auto-reversing. Manual adjustment required.

Happy to walk through the Mines reconnect path if that’s the interesting bit.
