Before the first spin of Razor Returns
Torpedo symbols land on the 5x5 grid at random, so the Free Spins Feature can start on the first spin or not at all during a session. How often the Free Spins Feature comes is not known in advance, and the result of one session is random whatever the RTP. An RTP describes an average over very many rounds, not the outcome you will see tonight.
Each spin on the 5x5 grid pays out under one RTP version at a time. Which of the three versions runs at Ocean96 Casino is shown only in the game rules, so read them before you place a first bet. Two versions of the same title can pay differently over time.
On the 5x5 grid during the Free Spins Feature, Mystery Symbols nudge down one position per spin, and each nudge lifts the Total Multiplier. The maximum win is a ceiling reached very rarely, and no session can be planned around reaching it. Treat it as a ceiling, not as an expectation.
