Quick Answer
Originals are Rheabet's own in-house games — Mines, Plinko, Crash, Limbo, Dice, Coinflip, Roulette, Blackjack, Baccarat, Hi-Lo, Keno, Tower, Rock Paper Scissors, and Chicken. Each one uses HMAC-SHA256 to turn a server seed (committed before you play), your client seed, and a nonce into the outcome — so any round can be re-derived and verified independently. Most carry a 1% house edge; European Roulette inherits its natural ~2.7% from the single-zero wheel. Win and your crypto withdrawal is auto-processed straight to your wallet, 24/7.
The 14 Rheabet Originals
Each game is grouped by the skill or mechanic it leans on. They all share the same provably fair RNG — only the payout math changes from one to the next.
Classic-Style Games
- Roulette — single-zero European wheel, 37 pockets. Inside bets (splits, corners, single numbers) and outside bets (red/black, dozens, columns) all pay 36 divided by the numbers you cover. Natural ~2.7% house edge.
- Dice — slider over/under from 0 to 100. Payout is 99 ÷ win chance, giving a 1% edge. A 50% target pays 1.98x either way.
- Coinflip — call heads or tails 1 to 20 times in a row. Each correct flip multiplies your payout by 1.98x; one wrong call and you lose everything staked.
- Rock Paper Scissors — multiplier builds with each consecutive win. Cash out whenever you want to lock in the run.
Skill / Strategy Games
- Mines — 5×5 grid, you set the mine count (1 to 24). Every safe tile bumps the multiplier. Cash out before you hit a mine.
- Tower — climb 9 rows, each with 1 to 3 safe tiles among the traps. Pick your difficulty: easy, medium, hard, expert, or master. Cash out at any level.
- Blackjack — single-deck 21, dealer hits soft 17. Hit, stand, double, split, and insurance are all available. A natural blackjack pays 3:2.
- Chicken — cross 20 levels of traffic, 20 tiles per level with 3, 5, or 8 death tiles depending on difficulty. Same payout formula as Mines on a smaller board.
Instant-Win Games
- Crash — the multiplier climbs from 1x; cash out before it crashes. If it crashes first, you lose the bet.
- Limbo — set a target multiplier (say 100x). The server rolls one number; land at or above your target and you win that multiplier. Higher targets mean a lower hit rate.
- Plinko — drop a ball through 8, 12, or 16 rows. Your risk level (low, medium, or high) shapes the payout curve across the bottom buckets.
- Keno — pick up to 10 numbers from 1 to 40 and the game draws 10. Payouts scale with how many you match, across four risk presets from classic to high.
Card Games
- Baccarat — 8-deck shoe, standard third-card rules. Player pays 2x, Banker pays 1.95x (5% commission), Tie pays 9x.
- Hi-Lo — full 52-card deck; guess whether the next card is higher or lower. The per-guess multiplier reflects the real probability based on the cards still in the deck.
How Provably Fair Actually Works
"Provably fair" gets thrown around loosely. Here's the real mechanism, in four steps, that lets you prove any Rheabet Originals round was honest.
The Server Commits a Seed Before You Play
Before a round, Rheabet generates a random server seed and shows you its SHA-256 hash. That hash locks Rheabet into that exact seed — it can't swap the seed later without the hash no longer matching.
You Provide a Client Seed
Your client seed sits right in the game UI and you can change it any time. Pairing a server seed you don't control with a client seed you do means neither side can pre-compute the outcome.
Each Round Uses a Nonce
The nonce starts at 0 and ticks up by one every round. The outcome comes from HMAC-SHA256(server_seed, client_seed:nonce:cursor) — a deterministic, one-way function. The same inputs always produce the same output.
Verify After the Fact
When you rotate to a new server seed, the previous one is revealed. Feed (server_seed, client_seed, nonce) into any HMAC-SHA256 tool and you can re-derive every round that seed produced. If Rheabet had lied about a single roll, the math wouldn't line up.
Notes on Edge and Strategy
The same 1% house edge across most Originals doesn't mean every game fits every player. Volatility, session length, and your risk appetite matter far more than chasing the "best" game.
Pro Tips
- Low-volatility picks for long sessions: Dice at low target multipliers, Plinko on low risk, Roulette outside bets. Small wins, high hit rate, slow bankroll drain.
- High-volatility picks for big swings: Limbo at 100x and up, Mines with 10+ mines, Plinko high risk, Crash auto-cashout at 5x and beyond. Frequent losses but the occasional 50x+ hit.
- Card games (Blackjack, Baccarat, Hi-Lo) reward real strategy. Basic blackjack strategy alone trims the house edge, and Hi-Lo's payout tracks the true remaining odds so it stays mathematically fair within the 1% edge.
- Crash and Limbo are mathematically equivalent to setting a target multiplier — the only difference is the UI and whether you can bail mid-flight (Crash) or you can't (Limbo).
- Rotate your server seed before a session if you plan to use provably fair verification. Rheabet only reveals the old seed once you've rotated to a new one.
Frequently Asked Questions
What's the house edge on Rheabet Originals?
Most Originals run a flat 1% house edge — Mines, Plinko, Crash, Limbo, Dice, Coinflip, Tower, Hi-Lo, Chicken, Keno, RPS, and Blackjack are all built around it. European Roulette keeps its natural ~2.7% edge from the single-zero wheel. Baccarat carries the standard 1.06% on Banker (with 5% commission) and 1.24% on Player.
Can I actually verify a round outcome myself?
Yes. Rotate your server seed so the old one is revealed, then take that seed, your client seed, and the nonce of the round you want to check and run them through HMAC-SHA256. You'll get the exact outcome Rheabet showed you. Verification tools live in the game settings, and any standard HMAC-SHA256 calculator works too.
Which Rheabet Original has the best odds?
Every non-Roulette Original shares the same 1% house edge, so none is mathematically "better" than another at the base level. The right pick comes down to the volatility you want — Dice and Plinko on low risk for slow grinds, Limbo and Mines for high-variance shots.
How are Originals different from the other games at Rheabet?
Originals are built in-house and use Rheabet's own provably fair RNG, which you can verify yourself. The thousands of third-party slots and live-dealer tables in Rheabet's 7,000+ game library use their providers' RNGs and usually bake a higher house edge into their RTPs.
