Watch out for the change in music and lighting after a non-winning cascade or collapse as it could be the moment the random Rainbow feature on this slot is triggered. The sequence will continue until no new winning clusters land on a new cascade. Any winning cluster will collapse, making room for more symbols to cascade into place.

A cluster of five to 25 matching symbols or in combination with wild symbols will award wins according to the paytable. Instead of spinning reels, the slot will cascade 64 symbols onto the grid at the beginning of every spin. They act at the same time as scatters with three needed on the grid in one cascading sequence to trigger the free spins. Rainbow coloured jars are the wild symbol which will have an increasing win multiplier attached when they are part of consecutive winning clusters. Wins for clusters of 25 or more symbols range from 10x to 100x the bet. Jammin’ Jars has six regular pay symbols – blueberries, plums, apples, raspberries, oranges, and strawberries.
