What makes our originals different

Most casino games come from third-party studios. Our originals are different: we write, audit and operate them ourselves. That means we control the math, we publish the house edge, and we can prove every result is fair. It also means the 50% rakeback applies to all of them — you're getting half the house edge back on games that already run leaner than the industry norm.

Provable fairness, in plain English

Every round combines a server seed (ours), a client seed (yours) and a nonce (a counter that increases each bet). Before the round, we commit to a hashed server seed so we can't change it after the fact. After you play, you can reveal the seeds and re-compute the result yourself. If the numbers match, the game was fair — and they always will. No trust required; it's math you can check.

House edge vs RTP — why it matters

RTP tells you the long-run return of a game; house edge is simply the flip side — what the casino keeps. We lead with house edge because it's the honest number. Castle Roulette, for example, runs at a 0% house edge, and the rest of our originals are tuned to be among the leanest you'll find. Pair that with 50% rakeback and the effective edge drops further still.

The games

Crash: ride the multiplier and cash out before it busts. Plinko: drop the ball and chase the high-payout edges. Mines: flip safe tiles and bank before you hit a bomb. Dice: classic over/under with adjustable odds. Blackjack and Video Poker: the table staples, provably fair. And Castle Roulette: our 0% house edge headliner. Each is built for fast, transparent play.

Originals and the 50% rakeback

Rakeback isn't limited to slots — it tracks your wagering across the originals too. Because these games already carry a low house edge, the half-back rakeback makes them some of the best-value bets on the site. Win or lose, you're getting a steady return on everything you stake.
