Read the rules before choosing a version
The 8x8 grid holds 64 cells, but nothing on this page can say how often the Free Spins round will start. Bonus timing is not known in advance. The result of one session is random whatever the RTP of the version you play. A session can end well below the amount staked, and it tells you nothing about the next.
Two RTP versions of Starlight Princess Super Scatter exist, and only the game rules show which one is in play. Both return almost the same share of the stake, so the gap is small. Read the rules before the first spin to see which version applies to your session.
x50,000 the bet is the highest win Starlight Princess Super Scatter can pay, and it is a ceiling reached very rarely. Hitting it is not something any player can plan for. Read the figure as a limit on the payout, not a target for the session.
