TL;DR
- Stake Originals (Mines, Plinko, Dice) run 99% RTP. Industry slot average: 96%. That is $30 less expected loss per $1,000 wagered.
- Keno is the exception in the originals suite: 4% house edge, same as slots.
- Provably fair proves result integrity, not that the house edge is what it claims. Both are confirmed at Stake.
99% RTP. That is what Stake Originals runs across Mines, Plinko and Dice. The industry average for video slots from Pragmatic Play, Hacksaw and Nolimit City is 96%. The gap is 3 percentage points, or $30 less expected loss per $1,000 wagered. Originals are not a winning game. They are the least-losing option in the crypto casino catalogue, and the only game category where every player can independently verify that no result was manipulated after their bet was placed.
Keno runs at 4% house edge within the same Stake Originals suite. Know the difference before you pick a game.

Why Originals Out-RTP Slots
Third-party slot providers (Pragmatic Play, Hacksaw Gaming, Nolimit City, Relax Gaming) licence their games to casino operators. The licensing fee is recovered through the game's house edge. A portion of every player's loss on a slot goes to the developer. To remain commercially viable, the developer sets the house edge high enough to cover their costs.
Originals are owned by the operator. Stake.com built Mines, Plinko, Dice and Keno in-house. No third-party licensing fee. The full house edge goes to the operator. Because crypto casinos earn revenue from volume rather than margin, they can publish a lower house edge (1% versus 4%) and still generate equivalent revenue from higher bet frequency.
| Game category | Typical house edge | Who captures the edge | RTP |
|---|---|---|---|
| Slots (major providers) | 4% | Split: provider + operator | 96% |
| Slots (own-brand at crypto casinos) | Variable | Operator | Variable |
| Stake Originals (Mines, Plinko, Dice) | 1% | Operator (Stake) | 99% |
| Stake Originals (Keno, 10-spot) | 4% | Operator (Stake) | 96% |
| Third-party live dealer (Evolution) | Variable by game | Split: Evolution + operator | Variable |
For session-to-session play, Dice, Mines and Plinko are the originals with the best EV profile. Keno is the exception.
Provably Fair: Full Walkthrough
Provably fair is a cryptographic verification system that proves a casino could not have changed a bet's outcome after the player placed it.
Step 1. Server Seed Generation
Stake's server generates a random server seed, hashes it using SHA-256, and publishes the hash to the player. The hash is a fingerprint: anyone can verify a given server seed matches a given hash, but no one can reverse the hash to discover the seed.
Step 2. Client Seed
The player provides a client seed. By default, Stake generates one automatically, but players can change it before any bet.
Step 3. Nonce
Each bet on the current server seed increments a nonce: a sequential counter starting at 1. The same server seed and client seed produce a different result on every bet.
Step 4. Result Generation
The game outcome is determined by combining: server seed + client seed + nonce, processed through HMAC-SHA-256. The resulting hash maps to the game outcome: a mine position on Mines, a ball path on Plinko, a dice roll on Dice.
Step 5. Verification
After the bet resolves, the server seed is revealed. The player can: confirm the server seed matches the hash published before the bet; repeat the HMAC-SHA-256 calculation with their client seed and nonce; confirm the result matches the published outcome. If the calculations match, the outcome was determined before the bet.
Stake's verification tool is available under the fairness menu. Every bet has a verification link in the bet history.
Provably Fair Does Not Apply to Slots
Third-party slots from Pragmatic Play, Hacksaw Gaming and Nolimit City are not provably fair. They use certified RNGs audited by external laboratories (iTech Labs, GLI, BMM). The audits confirm the RNG produces statistically random outcomes at the certified RTP. Players cannot independently verify individual slot spin outcomes; they rely on the audit process and regulatory oversight.
Both systems can produce fair outcomes. The difference is transparency: provably fair allows per-bet verification; RNG certification allows statistical audit at the population level.
Card Grid: The Three Originals
Plinko
A ball drops through a triangular peg grid. Three risk levels (Low, Medium, High) and five board sizes (8-16 rows). The distribution is binomial: centre slots hit frequently, extreme slots hit rarely. At 16 rows, the centre slot hits 19.64% of drops; the extreme corner hits 0.00153%. 1% house edge across all configurations.
Key takeaway: high-risk Plinko on a small bankroll produces near-certain ruin before an extreme-slot hit.
Mines
A 25-tile grid with configurable mines (1-24). Each safe reveal increases the multiplier per the formula: 0.99 x C(25,n) / C(25-m,n). At default 3 mines, 1 reveal pays 1.13x; clearing all 22 safe tiles pays 2,477.7x with a 1-in-2,300 probability. 1% house edge.
Key takeaway: on low mine counts, cash out early. The multiplier curve is slow, and the risk-to-reward inversion point arrives before most players realise.
Dice
Roll under (or over) a chosen threshold. Win chance configurable from 0.01% to 99.99%. Payout = 99 / win-chance%. At 50%: 1.98x. At 1%: 99x. At 0.1%: 990x. The 1% house edge is constant at every win-chance setting.
Key takeaway: every win-chance setting has identical EV. The payout formula embeds the 1% house edge regardless of the number you pick.
