Flush Originals are the games built in-house rather than licensed from a studio, and that shows up in one number: most of them return 99% or more, against 94-96% for a typical online slot. There are 20 of them, covering crash, dice, plinko, mines and the full table-game set. Every round is settled by a hash committed before you bet, so you can verify it yourself. Play at flush.com/originals.

The house edge is the reason to play Originals over licensed content, so here is the whole list rather than a selection.
| Game | RTP | Type |
|---|---|---|
| Blackjack | 99.43% | Card |
| Plinko | 99.16% | Grid |
| Keno | 99.07% | Number draw |
| Crash | 99.00% | Multiplier |
| Dice | 99.00% | Probability |
| Mines | 99.00% | Grid |
| Limbo | 99.00% | Multiplier |
| Hilo | 99.00% | Card |
| Wheel | 99.00% | Multiplier |
| Slider | 99.00% | Probability |
| Dragon's Tower | 99.00% | Path |
| Cross the Road | 99.00% | Path |
| Video Poker | 98.94% | Card |
| Baccarat | 98.94% | Card |
| Diamonds | 98.29% | Instant |
| Cross The Lake | 98.00% | Path |
| Roulette | 97.30% | Table |
| Traffic Jam | 95.00% | Path |
| American Roulette | 94.74% | Table |
| Coin Flip | 92.00% | Instant |
Three of these are deliberately not high-RTP, and it is worth knowing which. American Roulette carries a double zero, which is why it returns 94.74% while single-zero Roulette returns 97.30%. Traffic Jam at 95.00% is the weakest of the three crossing games, where Cross the Road runs the same mechanic at 99.00%. Coin Flip at 92.00% is the lowest on the board, and Dice set to a 50% win chance gives you the same bet at 99.00%.
Crash: A multiplier climbs from 1.00x and stops at a point fixed before the round began. Cash out first and you keep the multiplier; miss it and the stake is gone. Your exit target is the entire strategy, because reaction speed cannot change a result that already exists.
Dice: Set a threshold and bet over or under. Win probability and payout multiplier are locked together by the RTP, so no position on the slider is worth more than another.
Plinko: Drop a ball through a pegged grid into a multiplier slot. Row count and risk level reshape the payout curve without moving the 99.16% return.
Mines: Uncover safe tiles while avoiding hidden mines, cashing out whenever you choose. You set the mine count, which trades survival odds against multiplier size.
Keno: Pick numbers and watch the draw. At 99.07% this is a very different proposition from conventional keno, which frequently returns between 70% and 92%.
It proves the result was fixed before you bet and was not altered afterwards. It does not prove the odds are generous, which is why the RTP table above matters independently.
Three values produce every outcome: a server seed generated by Flush, a client seed you can set yourself, and a nonce that increments each round. They are hashed with SHA-256. You see the hashed server seed before playing, so Flush is committed to a result it can no longer change. Rotate your seed pair afterwards and the plain server seed is revealed, letting you recompute the hash in any SHA-256 tool and confirm it matches.
The step most players skip is setting a custom client seed. Leave it untouched and you are trusting that Flush picked yours fairly too. Set it yourself and the proof closes.

Which Flush Original has the best RTP?
Blackjack at 99.43%, then Plinko at 99.16% and Keno at 99.07%. Blackjack's figure assumes correct playing decisions; misplaying hands lowers it.
How many Flush Originals are there?
20, spanning multiplier games, probability games, grid games and table games.
How do I verify a provably fair result?
Set a custom client seed, play, then rotate your seed pair to reveal the server seed. Hash the server seed, client seed and nonce with SHA-256 and compare against the outcome.
Is there a house edge on Originals?
Yes. Even at 99.43% the house retains a margin over time. Provably fair means each round is unmanipulated, not that the game is break-even.
Which cryptocurrencies are accepted?
Nine: Bitcoin, Ethereum, BNB, Litecoin, USDT, USDC, Tron, POL and Dogecoin, all with identical limits, sub-two-minute payouts and zero platform fees.
Do Originals count toward VIP and rakeback?
Yes, on the same basis as every other game at the casino.
What wallet do I need?
MetaMask, any WalletConnect-compatible wallet, or Google sign-in.
Gamble only for fun and within your means. A 99% RTP is still a negative expectation over time, not an edge, and fast rounds make it easy to stake more than planned. Set a budget and breaks, and avoid chasing losses. Responsible gaming info. 18+.
