Every one of the 14 paid back more than it took, and still did at the bottom of its own margin of error.

We ran 339,349 spins across PG Soft's 14 games in the lab. The weighted average was 142%, against the 96-97% the provider publishes. Put in 100, get back 142. No real-money slot does that.

So treat everything on this page as a description of how the game behaves, not as what a real-money version would pay. The other figures (how often free spins land, how often a spin pays anything) may have been loosened the same way.

This is PG Soft's own official demo: the launch token our collector uses is the same one PG Soft's own demo page hands out. What we cannot measure is the real-money version, so we are not saying that one is rigged. We are saying the free version people practise on is not the same machine.

The dashed line is the official RTP. The more spins, the closer it should get, and the narrower the shaded range. The chart is redrawn every hour; the spin counter at the top is live, so it runs a little ahead.

The official numbers, and whether they hold up

Read from the game's own settings

Official figure is outside the range. Needs more spins

130.7%likely range155.5%

Official RTP is 96.95%. Over 21,020 spins we measured 143.1% (likely range 130.7% to 155.5%). The official figure falls outside that range, which is unusual and worth more spins before we draw any conclusion.

Why the range is so wide: almost all of a slot's payback sits in a handful of rare big wins, so the measured return stays noisy for a very long time. Getting this range down to ±1 point on a high-volatility game takes millions of spins. That's why we lead with hit rate and free-spin frequency instead. Those settle within weeks.

Looking for the free demo?

Every slot here has an official free demo run by PG Soft itself, and that is exactly where our numbers come from. We don't link out to anyone, so here's how to find it yourself: search the game's name together with "PG Soft" and open the result on the provider's own website, where each game has a Demo button. No account, no deposit.

Why bother finding the official one: a casino can license a lower-RTP version of the same game. The demo on the provider's own site is the default configuration, the one our numbers describe.

FAQ

Is this data real?
Yes. Every number on OddsLab comes from spins we actually ran on the provider's own official free demo, recorded by a program that logs every spin and reconciles the balance after each one. If the balance doesn't match the win minus the bet, the line stops and we don't keep the data.
Does a long losing streak mean a win is coming?
No. Each spin is independent. Our hot-slot experiment groups real spins by drought length: the chance of free spins is the same after 10 empty spins as after 500.
Is the demo the same as real-money play?
The game maths in the demo is the provider's default configuration. Casinos can license lower-RTP versions of the same game, so real-money results can be worse than what we measure. Never better.
Can I use this to beat the slot?
No. These numbers describe a game's character: how often it pays, how many "wins" are really losses, how rare the big wins are. None of it predicts the next spin, and over time every slot pays back less than you put in.
Why don't you just publish the measured RTP?
Because at our sample sizes it isn't a usable number yet. On a high-volatility slot the measured return can be fifteen points off in either direction after 40,000 spins. We show it with its margin of error and lead with the figures that are already accurate.
