Why a ceilings page — and how to read it
What "ceiling" means
Studios ship the same game in several RTP configurations. The number here is the
highest one — the theoretical best. It is useful as a benchmark and to model any title, but it is
not what your casino pays. Volatility, max win and mechanics
are studio-set and don't change between casinos, so those are reliable everywhere.
The deployed gap
Where we've verified a title in-game at a UK casino, the "Deployed (worst UK)" column shows the real figure and the gap to the ceiling. A big gap is pure extra loss taken by that operator. As we verify more platforms, more gaps will appear. For confirmed deployed figures, see the
Platforms page.
Frequently asked questions
What is theoretical RTP (the RTP ceiling)?
The best-case Return to Player the studio publishes — the highest version a game can run. Most casinos deploy a lower one, so treat it as a benchmark, not what you'll be paid.
Is a high-RTP slot the same as a low-volatility slot?
No. RTP is the long-run return; volatility is how streaky wins are. Both matter — higher RTP and lower volatility each improve your chance of finishing a session ahead.
Why is the RTP here different from my casino?
This is the studio ceiling. Your casino has likely deployed a reduced version — check its in-game rules panel for the figure that applies to you.
Does a high theoretical RTP make a slot a good bet?
No. Even at its ceiling every slot returns under 100%, so it loses over time — a high ceiling just loses it more slowly.
