RTP versions listed in the game rules
Each spin lands symbols on the 5x4 grid at random, and no spin shows when the bonus round is due. The result of one session stays random whatever the RTP, so a quiet run says nothing about the next one. Nobody can predict how often the bonus appears, so treat every session as a single random run.
The 20 paylines pay as the rules set, and only the game rules show which RTP version Winshark Casino runs for this lobby slot. Check that section before you start, because the version sets the RTP your bets run on.
A winning combination pays a multiple of the bet, and the top multiple for Greedy Wolf is x3,000. That figure is a ceiling, not a target, and a session reaches it very rarely. Read the top prize as the most the game can pay, never as an expected result.
