Jumbo Safari results stay random
Each spin lands symbols on the 5x3 grid, and scatters decide whether the Free Spins round starts, so no one knows in advance how often the bonus comes. The result of one session is random, whatever the RTP says. The RTP describes the return over a very long run, not the outcome of the next spin.
Each round plays 20 fixed paylines on the 5x3 grid, and all of them are always active. Which RTP version runs on this game is shown only in the game rules. Read the rules before the first spin to confirm the version in play.
Symbols pay left to right from the leftmost reel on each of the 20 paylines, and only the highest win per line is paid. The maximum win of Jumbo Safari is a ceiling that players reach very rarely. It marks a limit, not a likely result, so no one should plan a session around it.
