Planned budgets versus random spins
Set your session budget before the first spin, because nobody can predict when the bonus round will land. How often Sugar Rush 1000 triggers its Free Spins is not known in advance, and the result of one session is random whatever the RTP version. Treat every spin as a result you cannot plan for, and stop when your budget is gone.
Check the game rules before you start, because only they show which RTP version this lobby runs. Note the version once and use it as a reference for your budget, not as a promise about any one session.
Decide how much a single win should matter to you before you bet. The maximum win of Sugar Rush 1000 is x25,000 times the bet, and that ceiling is reached very rarely. Plan around the ordinary outcome of a session, not around the top prize, because the top prize is not something you can count on.
