Leveling Up is how you mark your progress through the game. Progress is marked by experience points which can be marked by the purple Experience Bar at the top of the playing screen. You gain experience points by betting. The fastest way to gain experience is by betting high. For example if you bet $5 per line on 20 lines you may receive 100 experience for that spin. So in this case, it pays to bet big!
Currently Jackpot Party Casino has a level cap of 1300. You will not gain experience points for future levels until we release them, therefore everyone who reaches level cap will stay there until new levels are released.
BOOST increases your experience per bet! Be sure to read more about it!
