# Summary

> Online casino app for LB Phone & YSeries. Provably fair flyUS crash, blackjack, slots, and shared-round roulette, all server-authoritative.

## Diamond Online — In-Phone Casino for QB-Core / QBox

**One resource. Four games. Server-authoritative wallet and outcomes. Provably fair seeds. Works on LB Phone and YSeries out of the box.**

Diamond Online lives inside the player's phone. Open the app, deposit cash from your bank into casino credits, and play any of the four built-in games. Every outcome is decided on the server using a commit-reveal seed scheme so players can verify results after each round.

### Headline features

* **flyUS crash** — Multiplier climbs until it crashes. Cash out before it does. Shared round, all subscribers see the same multiplier in real time.
* **Blackjack** — Standard 6-deck shoe, dealer hits soft 17, 3:2 blackjack payout. Game logic runs in UI, bet/settle decided server-side with anti-replay protection.
* **Slots** — Weighted reels, 3-of-a-kind and pair payouts. Symbol weights and payout tables stay server-side (never shipped to client).
* **Roulette** — Single-zero European, shared round, red/black/green colour bets. HMAC-derived pocket from server seed.
* **Server-authoritative credits** — Wallet, bets, deductions, and payouts run through `oxmysql`. Client never decides money.
* **Provably fair** — `SHA256(serverSeed)` published before each round, server seed revealed after. Players verify outcomes themselves.
* **Phone-agnostic** — Auto-detects LB Phone or YSeries. Force either via config.
* **Framework-agnostic** — Auto-detects QB-Core or qbx\_core.
* **Anti-extractor by design** — Config (bet limits, payouts, slot weights, role thresholds) stays on the server. Client fetches values via `lib.callback` on demand so Lua dumpers can't read odds.
* **Rate-limited everything** — Every callback per-player, per-action throttled to kill injector spam.
* **Lifetime stats + history** — Last 100 bets across all four games, total won, total wagered, role progression on the profile tab.
