The x14,000 maximum win ceiling
Three BONUS symbols on reels 1, 3 and 5 trigger Free Spins in Pandemic Rising, yet how often that happens cannot be known in advance. Every spin draws its symbols at random, so no bonus round is due after any number of spins. The result of one session is random too, whatever the RTP.
Four RTP versions come with Pandemic Rising, and the version Westpoint Casino runs is shown only in the game rules. Check the rules inside the game before you play, so you know which version you are on. Each version pays back a different share over the long run, and no single session follows that share.
x14,000 is the ceiling for Pandemic Rising, a multiple of the bet that is reached very rarely. Read it as the top of the scale, not as what a session should expect. Every win below it is also random, so the page cannot tell you when a big one will land.
