Casino game hub on Solana: decentralized casino jackpot smart contract, plus frontends for mining, crash (Plinko), coinflip-style games, Blackjack, Roulette, and Baccarat. Casino-game-hub includes a Solana jackpot with ORAO VRF and games that can run without third-party APIs by using fee-based on-chain randomness.

What this repo is

A casino game smart contract and casino-game-hub of game frontends: jackpot (Solana/Anchor + ORAO VRF), mining (treasure/trap grid), crash (Plinko-style backend), coinflip-ready patterns, Blackjack (EVM/Solana/Sui), Roulette, Baccarat. Use it as a casino dev toolkit or deploy the jackpot and games as a full casino stack.

Slot-style games without third-party API (fee-based)

You can run slot-style and other games without any third-party randomness API. Use fee-based on-chain randomness (e.g. block hash / timestamp or a small protocol fee) instead of paid VRF or external oracles. That keeps costs down and avoids API keys or per-request fees while still giving you on-chain fairness. The hub’s Roulette and similar programs show fee/timestamp-based RNG patterns you can reuse for slot logic.

Code features

• Jackpot (Solana/Anchor)

  • Create game, join, set winner, claim reward.
  • Config: round time, min deposit, max joiners.
  • ORAO Network VRF for verifiable randomness.
  • Instructions: configure, create_game, join_game, set_winner, claim_reward.

• Mining game

  • Grid-based mining: uncover tiles, avoid traps, collect treasure.
  • Configurable bet, density, rewards.
  • Provably fair backend; optional leaderboard.

• Crash / Plinko

  • Crash-style backend (Node): difficulty levels, odds, server-side result generation.
  • Plinko frontend (React) with difficulty selection and bet flow.

• Blackjack

  • EVM (Solidity), Solana (Anchor), Sui (Move).
  • Bet, deal, hit, stand; token transfers on-chain.

• Roulette

  • Solana (Rust) and EVM (Solidity).
  • Bet amount + guess; fee/timestamp-based RNG (no third-party API).

• Baccarat

  • Game engine and tests under Frontend/Baccarat/.

• Slot-ready pattern

  • Roulette and similar programs demonstrate fee-based on-chain RNG you can reuse for slot games without third-party API or VRF fees.

• Shared tooling

  • TypeScript/Node CLI and lib for contract interaction.
  • IDL, tests, multi-chain (Solana, EVM, Sui) examples.
