Space is where studios put their most abstract mechanics. Freed from having to look like anything real, sci-fi slots host expanding grids, gravity-defying symbol drops, infinite multiplier ladders and the kind of reel geometry that would look absurd on a fruit machine.
The result is one of the catalogue's more experimental collections — if you want to see what a studio does when it is not constrained by a familiar setting, start here. RTP figures are shown on every card.
RollHub currently lists 127 space games you can open straight from this page. Every card shows the game's RTP before you play.
Ranked by published RTP among the most-played titles here. RTP is the long-run average return per 100 wagered, not a prediction for any session.
