Day by day, since we started recording. Short periods swing hard — one large win moves a day's RTP well past 100% without saying anything about the game's long-run return.

Difference

Magnum Opus is advertised at 96.00%. Measured across every tracked bet on Stake it returned 94.64%, 1.36 pp lower than the published figure.

The advertised figure is the studio's long-run theoretical return. The measured figure is what players actually got. Short-run luck moves it either way; the more bets a game has, the closer the two converge.

What these numbers mean

RTP
RTP (return to player) is the share of wagered money returned to players as winnings. These figures are measured — what players actually got — not the theoretical RTP a studio publishes. Over a single day the number swings widely because a few large wins move it; the all-time row is the meaningful one.
Turnover
Turnover is the total amount wagered in the period, converted to a USD equivalent across every currency accepted.
Bets
Bets is the count of individual wagers placed.
GGR
GGR (gross gaming revenue) is what the house keeps: turnover minus the winnings paid out. When RTP for a period rises above 100%, players finished ahead and GGR is negative.

Frequently asked questions

What is the real RTP of Magnum Opus on Stake?

Across all tracked play, Magnum Opus has returned 94.64% to players over 1,504,881 bets and $1.30M of turnover. Shorter periods differ — see the day, week and month rows above.

Why does this differ from the advertised RTP?

Endorphina publishes a theoretical RTP calculated over billions of simulated rounds. The figure here is the measured result of real bets on Stake over a finite sample, so it lands near the theoretical number but rarely on it exactly.

Can a game show an RTP above 100%?

Yes, over short windows. It means players won more than they staked in that period — usually one large payout against modest turnover. It is variance, not a permanent edge, and it evens out as the sample grows.

How often are these figures updated?

Our crawler refreshes every tracked game on a rolling cycle, so each game is re-read every few hours.
