5 reels, 10 lines that pay both ways, expanding wilds that respin · Provably fair
Five reels, three rows and ten lines that pay both ways: three, four or five of a symbol in a row from the left reel or from the right one.
The wild lands on the middle three reels. When it does it fills its whole reel, stands in for every symbol, and holds while the other reels spin again. Every new wild expands and gives another respin, up to three, when all the middle reels are wild.
It returns exactly 94.5% of everything bet, worked out from the reels themselves. Each spin comes from your own provably fair seed pair the moment your bet is placed. Check any spin on the Provably fair page.
