Ordinary spins behave like a steady breeze. Once free spins begin, every spin lifts the multiplier one step until it reaches the top step and stays there.
Free spins that ride a rising thermal
A Rising Thermal island keeps its lift in reserve until the feature. When scatters open the free spins, the opening spin pays at the bottom step of the thermal.
Every spin afterwards rises by a step, and once the highest step is reached the multiplier sits there for the rest of the feature. Low-volatility thermals rise 1×, 2×, 2×, 3×; medium ones 1×, 2×, 3×, 4×, 5×; high ones 2×, 3×, 5×, 8×, 10×. All five Rising Thermal islands on Kiteborne Isles are medium volatility, so each of them climbs from 1× to 5×.
Worked example. On the 1×, 2×, 3×, 4×, 5× thermal, a line worth 6 Play Credits pays 6 on the first free spin, 18 on the third and 30 on the fifth and on every free spin after it.
