What is RTP Variant?

An RTP variant is one of several configured returns a studio ships the same game at, leaving the casino to choose which one it runs. The game looks identical either way — same art, same features, same name in the lobby — and the figure can differ by several percentage points. Play'n GO's Fire Joker is 96.15% by default and also ships at 91.23%. Reactoonz is 96.51% with a 91.49% build behind it. Pragmatic and Nolimit City do the same across much of their catalogues. Five points is far larger than most players assume the gap between two casinos can be, and it is not disclosed in any lobby: the only reliable place to read the figure you are actually playing is the game's own information panel, opened after the game loads. A site quoting a single RTP for a game with variants is quoting the default, which may not be the build in front of you.
