Regardless of where you’re from, you’ll be happy to know that It’s a Mystery is available to players worldwide; including USA casino players!

It’s a Mystery offers 5-reels and 25-lines of gaming excitement. It features scatters, wild symbols, and substitute symbols which can help you produce some big wins!

The best part about the It’s a Mystery Slot Machine is its fantastic bonus round; called the Portrait Puzzle Feature. This feature is triggered when three or more “It’s a Mystery” symbols appear on the screen. If you can’t get three of these symbols, don’t worry, because this feature is also guaranteed to trigger at least once every 150 spins! Once triggered, you will go through two different puzzles. The first one will award you with up to 50 free spins and the second one will award you with up to a 6 times multiplier! If you complete either puzzle, you’ll be awarded with a bonus of 500 times your bet!
