Online slot games employ a range of different game mechanics. They serve many purposes such as keeping the play from getting monotonous.
Among those mechanics is the expanding reels feature. Many of the most beloved slot titles on BetMGM utilize this feature to award some of their best prizes.
While many games in BetMGM’s library of thousands of slots feature expanding reels, a few are worthy of the can’t-miss status. They all have that expanding reels mechanic in common but have different strengths otherwise.
Best Expanding Reels Slots Begin With Dancing Drums
Like all games on this list, Dancing Drums starts with a standard number of reels. However, landing the right symbol combinations can activate additional reels, exponentially improving your chances of cashing in on one of the game’s paylines.
Besides the expanding reels, Dancing Drums makes its case for one of the best Asian-themed slots with its stunning visuals and four jackpots. Scatter symbols, wild symbols, and a bonus game also heighten the excitement.
Dancing Drums is also a great start to checking out slots with expanding reels because of its manageable volatility.

Hotline 2 Calls Up Place Among Best BetMGM Casino Games
If you were a fan of the television show “Miami Vice” in the 1980s, Hotline 2 will invoke some nostalgia for you. The expanding reels keep this game from feeling stuck in the 20th century, though.
What really makes this game stand out from the crowd is the fact that it not only offers expanding reels but expanding wilds as well. You can enhance your chance of securing those expanding wilds with the Hotline bet option, too.
With free spins you can reactivate in perpetuity if you get lucky enough, Hotline 2 might have you looking back fondly upon it after you play it the first time.

Mystery Express Gets You Right Into the Expanding Reels Action
Slot players who love murder mystery classics are on the right track with Mystery Express. BetMGM gives you plenty of reasons to register and try out this game, including its expanding reels.

Mystery Express certainly has that capability with several bonus mini-games, capable of awarding massive multipliers.
