Prioritize these special features as you play Mystery Crazy 40 Bucks slot online:

Wild

As is the norm, the 7 wild card steps in for all regular symbols to complete winning lines. But this doesn't happen with the Banknote and Mystery symbols. Better still, the wild can also show up next to 2 or more matching icons on a payline, earning you a payout just like regular symbols would. Lastly, the 7 wild icons can even pay you out by themselves if you manage to land enough of them on a payline as tabulated above. 

Mystery

One spin in the Mystery feature could flip your luck.  Mystery Crazy 40 Bucks’ Mystery symbols drop only on the middle three reels, but they light up the grid when they do. Up to four can appear in each of those reels, so you can land 12 mystery spots in a single round. All Mystery symbols transform into the same symbol once the reels stop. If three or more of the same symbols line up on consecutive reels starting from the left, you win. You'll trigger the Crazy Bucks Jackpot if at least three Banknotes show up after the transformation.

Jackpot Game

The jackpot mini game kicks in when you land at least three Banknote symbols in a single spin. Each Banknote shows multipliers like x1, x5, or even x10. You'll start with three spins and hit random multipliers of up to x50. Fill a full column to unlock extra rewards like the MAD Jackpot or WOW multiplier.

Multiplier Game

A Gamble button may appear on your screen after a lucky spin. Hit it, and you'll enter a fast-paced side game. The multiplier game presents a Black $ and Red $ button. Pick one and take a shot at guessing the color of a hidden coin, and double your win.
