Jackbox Pearl Upgrade™ is a 3-Reel 3-Row Video Slot. 3 double Pearl symbols trigger Feature Games.
Each Reel gets split in the middle, so the Table switches to a 6-Reel-3-Row Table. The triggering double Pearls transform into single Pearls and get placed accordingly on the new Reels. Pearls are sticky during Pearl Feature. Each new Pearl resets the remaining Feature rounds to 3 during Pearl Feature. The Pearl Feature ends when all Feature rounds are played or all positions are filled with pearls. At the end of the Pearl Feature all pearl values are added up. This is the win of the Pearl Feature. Possible Pearl values are 100, 50, 20, 10, 5, 3, 2, und 1 multiplied by the bet. If all positions are filled with Pearls at the end of the feature, MEGA Prize is triggered. MEGA Prize is 1000 times the bet.
Pearl upgrades can only happen during Feature Games. At the end of a spin, every new Pearl upgrades other Pearls in either the same Reel, Row, or both. Every upgrade increases the Pearl value.
There are 3 special pearls: MINOR, MAJOR and MAXI. The Pot prize of the Pearl is added together with its value at the end of the feature games.
Feature Games can be purchased for 100x the current bet. When choosing the Buy Feature Games Feature, a Feature Games Trigger round will start. Buy Feature Games Feature is not available during Feature Games.
The theoretical return to player for this game on the current bet level is 95.07%. The theoretical return to player during the Buy Feature Games Feature on the current bet level is 95.49%.
