Spribe
Spribe demos: Aviator, Mines and Plinko — three instant games, all at 97% RTP, all Provably Fair. What each one is, what the multiplier ceilings really are, and why none of them is a slot.

Spribe is the studio behind Aviator, the game that turned “crash” into a casino category. It makes instant games rather than slots: no reels, no paylines, no free spins — a round that lasts seconds and a decision that is yours.
We carry three of them, and the first thing to know is that all three publish the same 97% RTP:
| Game | Released | What you decide | Listed ceiling |
|---|---|---|---|
| Aviator | 2019 | when to cash out while the multiplier climbs | no fixed ceiling — the limit is the operator’s |
| Mines | 2021 | how many mines to hide on a 5×5 grid, and when to stop revealing | 10,000× |
| Plinko | 2021 | the risk colour (green, yellow, red) and the number of pins (12, 14, 16) | 555× |
Provably Fair is the point
Every Spribe game we list is Provably Fair: the result of a round is fixed by seeds before it is played, published as a hash, and checkable by the player afterwards. In Aviator, the round’s result is built from the server seed and the client seeds of the first three players, with SHA-512; Plinko uses SHA-256 for every left-or-right bounce. Aviator’s randomness has been audited by iTech Labs, GLI and BMM Testlabs.
What Provably Fair proves is that the round was not changed after you bet. What it does not prove is that the game is in your favour — the 97% RTP means the house keeps 3% of everything staked, whatever strategy you use.
Why these are not slots
The pages that describe Aviator as a “slot with 97% RTP and high volatility” are describing a game that does not exist. In all three games the risk is a setting you choose:
- In Aviator, cashing out at 1.5× every round is a low-variance game; waiting for 20× is a very high-variance one.
- In Mines, more mines make the multiplier climb faster and the round end sooner.
- In Plinko, the red ball and 16 pins stretch the distribution; the green ball squeezes it.
That is also why we do not print a volatility figure for them: there is no single answer to print.
Where our numbers come from
⚠️ Spribe’s own website is a single-page app that returns no game data to a normal request — not for Aviator, not for Mines, not for Plinko. Every figure here comes from slotcatalog, corroborated by other aggregators, and each game page says so in its spec card. When Spribe publishes its specs in a readable form, we will switch the source.
