Knowing the limits before you bet
Choosing a bet on Sugar Rush 1000 means accepting that you cannot know when the Free Spins will start. Free Spins come from Scatter symbols, and how often they land is not known before you play. The result of one session is random whatever the RTP version, so the long-run figure says nothing certain about the session you are about to play.
Before you rely on any return figure, read the game rules, because the RTP version in use is shown only there. The game runs one of several RTP versions, and each version pays back a different share of the stake over the long run. Check which one applies before you choose a bet.
Weighing the top prize starts with knowing its size. The maximum win is x25,000 of the bet, and that ceiling is reached very rarely. No bet size and no session plan makes it a target you can reach on demand, so treat it as the upper limit, not as an expected result.
