Opening the rules panel ahead of any bet
Choosing your bet on Dino P.D. does not set when the bonus round arrives. How often the free spins come is not known in advance, and no spin tells you when the next one will land. The result of one session is random whatever the RTP version, so a high RTP never promises a win in any single session.
Deciding whether a version suits you starts with the game rules. The RTP version this site runs is shown only in those rules, so open the rules panel before your first bet on Dino P.D. Each of the three versions in the RTP table is a separate setting, and the rules panel names the one in use.
Picking a bet size decides how large the top prize is in money. The maximum win is a ceiling of ten thousand times the bet, and it is reached very rarely. Most rounds on Dino P.D. end far below it, so treat the ceiling as the outer edge of the paytable rather than a likely result.
