How does the free spins feature work?

3+ jam jars appearing in one spin trigger 6 free spins with roaming multiplier wilds.

Is Jammin' Jars 2 better?

The sequel adds a Giga Jar feature but has lower RTP. The original is still preferred by many.

Wild Jar Multipliers

Jam jar symbols act as wilds and increase their multiplier by 1x for every win they're part of. After a cascade, jars move to new random positions — if they create another winning cluster, the multiplier grows again. In free spins (triggered by 3+ jars), multipliers can reach staggering levels.
