BTCGOSU Labs tracked 892,777 real Mines bets across 25 crypto casinos over the week of 22 to 28 June 2026, the largest study of its kind we’ve run. We found that RTP on this game isn’t fixed across the industry, it varies by casino, and raw bet volume doesn’t tell you nearly as much about a casino as it looks like it should.
This piece is the case study of both. Gamdom and Stake are the two most extreme casinos in that same dataset, and putting them side by side makes each finding concrete.
Gamdom accounts for more Mines volume than any other casino we tracked, 244,048 bets, more than a quarter of everything in the sample. Stake barely registers by comparison, 22,720 bets, a fraction of Gamdom’s total. And yet more distinct accounts played Mines at Stake that week, 3,748 of them, against Gamdom’s 2,315. This says nothing about either casino’s overall size, only about Mines specifically, during the week we tracked. On that one game, in that one week, the bigger number came from fewer people.
One Gamdom Player Bets 17 Times More Often Than One Stake Player
That gap only makes sense once you divide the numbers properly. Gamdom’s 244,048 bets, spread across 2,315 players, works out to roughly 105 bets per person. Stake’s 22,720 bets, spread across 3,748 players, works out to just 6.
Gamdom isn’t the biggest casino in our dataset because more people play there. It’s the biggest because the people who do play there play constantly. A typical Stake user places a handful of bets and moves on. A typical Gamdom user plays more than seventeen times as often.
Half of Gamdom’s Volume Comes From Ten Accounts
The concentration goes even further at the top. Out of Gamdom’s 2,315 players, the top 10 alone account for 49.8% of the casino’s entire Mines volume. Roughly half of everything wagered at the biggest casino we tracked came from ten people.
Stake’s top 10 look nothing like that. They account for just 5.2% of its volume, spread across a base of 3,748 players who mostly bet a handful of times each and leave. Where Gamdom’s size comes from depth, a small number of players betting constantly, Stake’s smaller footprint comes from breadth, a much larger number of players each betting lightly.
Gamdom’s Odds Are Better. Its Results Don’t Show It.
Here’s the part that doesn’t add up on the surface. Our main Mines report found that Gamdom runs the game at 100% RTP, a genuine zero house edge, while Stake runs the same game at 99%, a real 1% edge in the casino’s favor. On the math alone, Gamdom is the better game to play.
But Gamdom’s win rate across our sample sits at 36.4%. Stake’s is 52.4%, sixteen points higher, on the worse game. That’s backwards from what the raw math would predict, and the concentration numbers above are the likely reason why.
Win rate in Mines depends heavily on how many mines a player sets. Fewer mines means safer, more frequent wins. More mines means rarer wins chasing a bigger multiplier. If Gamdom’s ten heaviest players, the ones responsible for half its entire volume, are consistently choosing higher-mine, higher-risk boards in search of bigger payouts, their results alone could drag the whole casino’s observed win rate down, even though the underlying game is paying out more generously than Stake’s. That’s a plausible explanation rather than a confirmed one, but it fits every number in this piece so far. Gamdom’s overall win rate reflects how a small number of aggressive, high-volume players actually bet there, not what the average, occasional player should expect from a game with better odds than Stake’s.
That’s also the part worth carrying into how you’d actually judge either casino. A casual player checking Gamdom’s stats and seeing a 36.4% win rate could easily read that as the game being worse or rigged, when the game itself is measurably fairer than Stake’s. The number is honest. It’s just describing a handful of whales, not you.
There’s a Third Difference, and It’s About Real Money
One more thing separates these two platforms, and it has nothing to do with odds or player counts. Every one of Gamdom’s bets in our dataset is placed in house credits, an in-house balance the platform issues and settles internally, not real crypto or fiat changing hands. Stake runs the opposite way, supporting 44 distinct real currencies. Whatever you bet at Stake is actual money moving. At Gamdom, it isn’t.
Bigger, Broader, and Genuinely Different Bets
None of this makes one casino better than the other. Gamdom offers a mathematically superior version of Mines and a deep, established core of players, at the cost of house credits instead of real currency and a table where ten accounts carry half the action, skewing its own headline numbers in the process. Stake offers real money and a genuinely broad base of casual players, at the cost of a worse house edge and a much smaller table overall.
