The same game does not always run at the same return. Operators can select a build, so a title paying 96.5% at one casino may pay 94.5% at another. Spread is the gap in percentage points between the best and worst version we have on file.
Two percentage points sounds small until you turn it into money. On a game running at 94.5% instead of 96.5%, every 100 dollars staked costs you 5.50 instead of 3.50. Over a few thousand spins that difference is larger than most welcome bonuses.
Why operators can do this
This is not cheating and it is not hidden, it is simply never advertised. Studios such as Play’n GO, Pragmatic Play and Nolimit City publish several RTP builds of the same title, and the operator picks one when it integrates the game. The lobby shows the same name and the same graphics either way.
The figure that applies to you is the one in the game’s own info panel at the casino you are actually playing at. It is worth opening it before a session rather than trusting a review that quotes the studio’s headline number.
Where a spread appears in the table above, the low end is the build somebody decided to run.
