Growing guide for Boiler House Wren
Rising free spins
Three or more scatters open a round of free spins. The multiplier climbs with every spin you play in the round: x2 → x3 → x5 → x8 → x10.
Wins pay left to right on 8 fixed lines from the first reel. Your stake is split evenly across the lines, and only the highest win on each line is paid. Every spin picks an independent random position on each reel; nothing adapts to your balance or how long you have played.
