The Microgaming online slots road map is always chock full of big releases, new features, and interesting bonuses.

There's no let-up this December, either. In the run-up to the new year, Microgaming will be releasing three more eagerly-awaited online casino games. Let’s take a closer look.

Action Ops: Snow & Sable

Reels: 5

Paylines: 10

Slot Highlights: Scatter, stacked wilds, free spins, wild reels.

Released: December 4, 2018

You might be forgiven for thinking Microgaming's first December release is based on a bona fide video game hit.

Indeed, Action Ops: Snow & Sable features some kick-ass heroines, lots of action, and amazing graphics. But the fictional world of Aurora has come straight from the Microgaming drawing board.

Built in conjunction with Triple Edge Studios (the brains behind innovative slots like Playboy Gold and Wicked Tales: Dark Red), Action Ops: Snow & Sable is centred round a neon soaked cityscape with two kick-ass road warriors.

Both Snow and Sable, when not modelling the latest latex catsuits, act as wilds. They can also appear stacked on the reels to improve the player's win. Trigger the free spins round and you will enjoy "locked and loaded" wild reels for the duration of the games. Best of all, the free spins can - and do - retrigger.

Despite the slot having just 10 paylines, the action can be pretty volatile.

Showdown Saloon

Reels: 5

Paylines: 15

Slot Highlights: Pick bonus, bonus wheel, mystery stacks, free spins.

Released: December 4, 2018

Indie developer Fortune Factory Studios signed an exclusive deal with Microgaming back in October to provide top-end slots. Romanov Riches was a popular first release, and hot on its heels comes the Wild West-themed Showdown Saloon.

The main feature of Showdown Saloon is the stacked reels. If you match at least two full reels, you will trigger (no Wild West pun intended) free re-spins. It's possible to fill the whole 3x5 reel set with a single giant symbol.

Showdown Saloon also features a regular free spins bonus with guaranteed matching stacks.

As in Action Ops: Snow & Sable, the volatility level can be quite high. However, with a few well-timed giant symbols and mystery stacks, the rewards could be worth the effort.

Book of Oz

Reels: 5

Paylines: 10

Slot Highlights: Re-spins, free spins, expanding symbols, magic theme.

Released: December 11, 2018

Loosely based on The Wizard of Oz, minus the singing Munchkins and wicked witches, Book of Oz has a modern slot feel.

The game is played on a set of five reels and features 10 fixed paylines. So far, so conventional.

But what marks Book of Oz out from other slots is the unique re-spin feature. After a base spin, players have the option to pay a little extra and re-spin a reel of their choice. The more potentially lucrative the reel is, the more you have to pay.

Free spins fiends can also indulge in some bonus games by hitting three or more book scatters. It's possible to activate up to 25 free spins this way. A symbol will be chosen at random at the start of the spins.

If it appears on the screen it can expand to fill the whole reel it's sitting on. Of course, free spins can be retriggered too.
