Stake Engine<\/strong> (since September 2026, simply Engine<\/strong>) is the Stake casino platform where third-party studios release their own slots. Its catalogue currently holds 7\u00a0649 games from 2\u00a0082 publishers<\/strong>, and since autumn 2026 they have been appearing not only on Stake but at other crypto casinos too.<\/p>\n

What sets Engine apart for a player: the maths of every game is public. We downloaded that data for the whole catalogue and worked out what stands behind the familiar \u201cRTP 96.7%\u201d. In short: the RTP is honest, but in a typical game 90% of spins<\/strong> end with nothing or with a payout smaller than the bet.<\/p>\n

What Stake Engine is<\/h2>\n

Stake launched Stake Engine in April 2025. It is a server and a toolkit with which an independent studio builds a game and releases it straight into the casino lobby. In return, the developer gets a share of the revenue from its game \u2014 at launch Stake announced 10% of gross gaming revenue.<\/p>\n

On 15 September 2026 the platform was renamed Engine and opened to other operators. A casino connects once and gets the games of all studios at the same time. According to Stake at the time of the announcement, the platform\u2019s games had generated more than $23 billion in turnover and 9.7 billion bets.<\/p>\n

There are many studios, but they differ greatly in size. 45% of the publishers in the catalogue have exactly one game. The top of the Engine section in the Stake lobby is taken mostly by two studios \u2014 Paperclip Gaming and Valkyrie.<\/p>\n

How an Engine slot works<\/h2>\n

The outcome is picked from a ready-made table<\/h3>\n

A conventional slot calculates the result at the moment of the spin. On Engine, the studio runs a simulation in advance and stores the finished outcomes \u2014 a typical game has 300\u00a0000 of them in the base mode. Each outcome has a weight (probability) and a payout.<\/p>\n

When you press \u201cspin\u201d, the server picks one row from that table. That is why RTP here is not an estimate \u201cbased on test results\u201d but an exact number: the sum of all payouts weighted by probability.<\/p>\n

The slot has no memory<\/h3>\n

The platform\u2019s rules require every bet to be independent. Jackpots, gamble features, round continuation and early cashout are prohibited.<\/p>\n

For a player this means one simple thing: the slot does not \u201csave up\u201d anything and does not \u201cowe\u201d anyone. A run of two hundred dead spins does not raise the chances of the two hundred and first.<\/p>\n

The tables are public<\/h3>\n

Engine runs a public fairness verification service. Using the server seed, the client seed and the spin number, anyone can reproduce a result and make sure it was taken from the published table.<\/p>\n

The same service returns statistics for every game mode. The whole breakdown below is built on them. For 163 games out of 7\u00a0649 the service did not return full statistics \u2014 they are not included in the spin calculations.<\/p>\n

What RTP Engine slots have<\/h2>\n

We took the base-mode RTP of every game \u2014 in the form the player sees it, with two decimal places.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n

\"Histogram:
How many Engine games fall on each base-mode RTP value, in steps of 0.1%.<\/figcaption><\/figure>\n

The three most common values are 96.00% (33% of games), 96.50% (17%) and 96.70% (11%). Only 4% of the catalogue is above 96.70%.<\/p>\n

The highest RTP in the catalogue is 98.95%, in a plinko game. Among slots, 98% does occur: for example, Waylanders Forge by Valkyrie. The lowest is 90.00%.<\/p>\n

The RTP of one and the same game can differ between modes. A regular bet, a boosted bet and a bonus buy are separate tables, each with its own figure. Check the RTP of the exact mode you are playing.<\/p>\n

How the metric itself works \u2014 how it is calculated and why it \u201cconverges\u201d only over the long run \u2014 is explained in a separate piece: what RTP in slots is - Slot rtp<\/span><\/a>.<\/p>\n

Are there Engine slots with 100% RTP?<\/h3>\n

No. We checked the modes of every game in the catalogue \u2014 there are 117\u00a0521 of them \u2014 and none reaches even 99.9%.<\/p>\n

An RTP of 100% means a zero house edge: over a long distance, players collectively get back everything they staked. Some crypto casinos announce such terms for their own in-house games \u2014 Dice, Mines, Plinko and the like \u2014 but not for slots from third-party studios. On the Duel site, for example, the in-house games are labelled \u201c100% RTP\u201d (checked on 12 November 2026). Gamdom and BiggerZ have announced similar terms. The list of games and the limits are different at every casino and change over time.<\/p>\n

And even a 100% RTP does not make a game a winning one. It is an average over millions of rounds, while a single session can still end either in profit or with a zero balance.<\/p>\n

Why an RTP of 96.7% does not save a short session<\/h2>\n

RTP shows how much is returned on average over a huge distance. It says nothing about how that money is distributed. In many Engine slots the distribution is very uneven: a large part of the return comes from rare big payouts.<\/p>\n

What the whole catalogue showed<\/h3>\n

We took the base mode of 7\u00a0486 games and looked at three shares: spins with no payout, spins with any payout, and spins that return at least the bet.<\/p>\n\n\n\n\n\n\n\n
Metric (base mode)<\/th>\nA quarter of games have less<\/th>\nMedian<\/th>\nA quarter of games have more<\/th>\n<\/tr>\n<\/thead>\n
Dead spins (payout 0)<\/td>\n62%<\/td>\n71%<\/strong><\/td>\n77%<\/td>\n<\/tr>\n
Spins with any payout<\/td>\n23%<\/td>\n29%<\/strong><\/td>\n38%<\/td>\n<\/tr>\n
Spins paying at least the bet<\/td>\n6%<\/td>\n10%<\/strong><\/td>\n16%<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Put simply, per 100 spins of a typical game: about 71 are dead, about 19 pay less than the bet, and about 10 pay at least the bet.<\/p>\n

In 24% of games, 94 spins out of 100 or more end \u201cin the red\u201d.<\/p>\n

Max wins, meanwhile, are huge. The catalogue median is \u00d715\u00a0000, 39% of games have a cap of \u00d725\u00a0000 or higher, and the record is \u00d71\u00a0000\u00a0000. But the chance of hitting the maximum in a typical game is roughly 1 in 3.3 million spins.<\/p>\n

12 games from the top rows of the lobby: what is left after 100 spins<\/h3>\n

We took 12 games from the upper part of the Engine section in the Stake lobby and reproduced 200\u00a0000 base-mode spins for each. Then we cut them into 2\u00a0000 sessions of 100 spins.<\/p>\n

The conditions are simple: a budget of 100 bets, 100 spins in a row at one bet each, with no bonus buys and no boosted bets. The \u201cremainder\u201d is the percentage of the budget left at the end of the session.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

\"Chart:
What share of the budget is left after 100 spins in a typical session.<\/figcaption><\/figure>\n

The RTP of 10 games on the list is 96.7%, Dragonspire Frostfall has 96.0%, and Waylanders Forge has 98.0%.<\/p>\n

In the softest game on the list (Dragonspire Frostfall) a typical session keeps 43% of the budget, in the harshest (Odin’s Vault) \u2014 10%. Between 14 and 25% of sessions end in profit, while losing 70% of the budget or more is the outcome of 27\u201369% of sessions.<\/p>\n

Note Waylanders Forge. It has the highest RTP on the list \u2014 98% \u2014 yet its median remainder is one of the lowest: 15%. A high RTP does not make a game soft \u2014 it only means the rare big payouts are even bigger.<\/p>\n

Something else stands out: five of the six Paperclip Gaming games have the same share of dead spins \u2014 81%. Games from one studio are built on a shared mathematical base; what changes is the theme and the artwork.<\/p>\n

The harshest scenario is losing 90% of the budget or more. In the four Valkyrie games on the list, 26\u201350% of 100-spin sessions end that way. Over 50 spins with a budget of 50 bets, it is 41\u201367%. For the other eight games the figures are 1\u20135% and 5\u201314% respectively.<\/p>\n

One game \u2014 five volatility levels<\/h3>\n

For some Engine games, several variants of the same mode with different volatility are published at once. There are 97 such games out of 7\u00a0649, and they include Paperclip Gaming hits. The RTP of the variants is identical, but the behaviour is not.<\/p>\n

Here are the five variants of a regular spin in Lazy Vampire \u2014 the same 200\u00a0000 spins and 2\u00a0000 sessions for each:<\/p>\n\n\n\n\n\n\n\n\n\n

Lazy Vampire: remainder of the budget after 100 spins at five volatility levels. BASE is the regular variant.<\/figcaption><\/figure>\n

With the same RTP, a typical session keeps anywhere from 13 to 72% of the budget. The price of softness is the chance of the max win: in the softest variant it is one in 19.5 million spins, in the regular one \u2014 one in 4 million.<\/p>\n

If a game offers a choice of volatility, it affects a short session more than the choice of the slot itself.<\/p>\n

Bonus buy: what comes back in a typical case<\/h2>\n

A bonus buy on Engine is a separate mode with its own table. In the six games we checked, its RTP matches the RTP of the regular game. We reproduced 20\u00a0000 purchases for each.<\/p>\n\n\n\n\n\n\n\n\n\n\n

A typical purchase returns noticeably less than its price: the median return is from 17 to 60% of the price. 19\u201327% of purchases pay for themselves, that is, roughly every fourth or fifth.<\/p>\n

The RTP is the same as in the regular game. What changes is the speed: ten purchases at 100 bets each equal the turnover of a thousand regular spins in a couple of minutes.<\/p>\n

Why max wins happen so often on streams<\/h2>\n

The explanation lies in the game modes. The max win is calculated from the base bet. In the expensive modes a purchase costs hundreds or thousands of bets, while the cap stays the same. So the maximum lands far more often there \u2014 and looks far more modest relative to the price.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n

Take Waylanders Forge. On a regular spin the \u00d780\u00a0085 maximum lands on average once in 2 million spins. In the most expensive mode, which costs 2\u00a0000 bets, it lands once in 276 purchases. But relative to the purchase price that is no longer \u00d780\u00a0085 \u2014 it is \u00d740.<\/p>\n

Per bet wagered, the chance of the maximum is of the same order \u2014 you can see it in the last column. The expensive modes simply turn over thousands of times more money in the same time.<\/p>\n

We do not know on what terms and in which modes particular streamers play. But no special terms are needed to explain frequent maximums on air \u2014 the published tables are enough. A clip with a \u201cmax win\u201d says nothing about what will happen at a regular bet.<\/p>\n

What this means for a player<\/h2>\n
