What do space slots look like?
Planets, aliens and starships. Most space slots build their symbols, wilds and bonus rounds around that, but the theme is the look only: how a slot pays depends on the game, so two space slots can play very differently.

No. Demo wins are play credits with no cash value. SlotSimba Savannah has no real-money play.
Do space slot demos work on a phone?
Yes. Every space slot demo runs in the mobile browser on iPhone and Android, with no app and no download.
