How to play MGM Grand Gamble mobile slot

The MGM Grand brand gets its own slot machine in the MGM Grand Gamble slot game, which is exclusive to LeoVegas casino and offers wins up to 50,000x your bet.

The MGM Grand Gamble mobile slot is a high volatility 5×6 reel, 50 pay line games created by Push Gaming where you’ll find Mystery Reveals, Instant Wins, Free Spins, a 96.52% RTP and a huge top win.

If you’re familiar with the Boss Bear slot or, more importantly, the Big Bamboo slot from Push Gaming, then you’ll know how this video slot works.

This MGM Grand Gamble slot is a reskin of the popular Big Win Big Bamboo slot machine, except you don’t find Panda and card suit symbols here; you find Dollar Signs, MGM Grand symbols and a variety of low-paying fruits.

The MGM Grand Gamble Slot Mystery Reveals

One of the main features of this MGM Grand Gamble slot is the Mystery Reveals feature. The Mystery Green MGM Grand symbols typically come stacked, and when the spin is complete, they will all reveal the same paying symbol.

It’s a feature you’ll find in many other online slots, including the Christmas Morning slot from Red Tiger and the Net Gains slot from NetEnt. However, there’s also a golden MGM Grand symbol, which acts very much the same as the green one, except it comes with more powerful features.

Features which can provide instant prizes between 1x and 5,000x your bet, up to 10x multipliers, trigger the free spins, collector symbols helping boost the instant prizes, or gamble scatters, which can also award free spins.

The Golden MGM Grand symbols don’t show up as often as the green ones, but when they do, they can often offer 40x bet plus wins on a good round. But it’s in the free spins where the Mystery Reveals come into play even further.

Win up to 50,000x your bet in the Free Spins

Landing bonus symbols plus a gamble symbol across reels 2, 3 and 4 triggers at least 4 free spins. Before the free spins start, you’ll find a gamble feature which, if you decide to press the gamble button and not the collect button, can reward you with more free spins or lose your chance to experience them.

The first time you trigger them, you’ll probably want to press the collect button cause during the free spins, there’s the chance to upgrade four of the lower-paying symbols into mystery reveal symbols.

For every 4th Bonus Scatter that lands in the free spins, it will upgrade a lower-paying symbol and give you extra free spins. The additional Mystery Reveals that are created will provide more opportunities to create 3, 4 and 5. of a kind wins and the potential to land the MGM Grand Gamble Feature with those big instant prizes up for grabs.

This is an extremely volatile slot. We’ve seen the same amount of spins land us just 4x our bet back, with another round landing us over 1380x our bet.

MGM Grand Gamble Review Conclusion

The MGM Grand Gamble slot online isn't anything we haven't seen before. It's a copy of the Big Bamboo slot with a different slot theme attached. However, that doesn't mean it is not a great slot to play; you know, have two great slots to play instead of one.

The Mystery Reveal feature shows up often, with the MGM Grand Gamble feature providing the bigger thrills just a little less often.

It's in the free spins bonus round that you feel like you can win the biggest wins, especially with the extra Mystery Reveal symbols and the additional free spins available.

Overall, the MGM Grand Gamble slot is only available at MGM-owned online casinos, including one of our favourites, LeoVegas. Go take it for a spin and see if you can win big on this Push Gaming-created slot.
