The Expandable Slot Machine

Grab a shovel, pickaxe and all the stacks of dynamite you can get your hands on. It’s time to work up a sweat in one of the top-producing gold mines in the world. Depicted on the reels of The Expandable video slot as a fedora-wearing male gold miner, you’ll be hoping to expand your balance by exchanging nuggets of solid gold for lots of real cash.

Developed by Berlin-based slot manufacturer Bally Wulff, The Expandable is set in the heart of a dark gold mine. As you can see from the backdrop, oil lamps and shimmering nuggets of gold provide the only glimmers of light deep below the surface. Stacks of dynamite also help to light up your surroundings, so cross your fingers for plenty of loud explosions as you spin the reels.

In terms of sound effects, you’ll be treated to an upbeat soundscape that promises to get you in the mood for gold-digging as the game loads. This is accompanied by a male voice-over announcing the title of the game. Unfortunately, you’ll have to endure the same stock sound effects that feature in most other casino slot machines developed by Gamomat (formerly Bally Wulff) throughout your time inside the gold mine. That is something we know frustrates many players who have tried online slots by Gamomat – us included!

No Need to Dig Deep

Well, not into your pockets anyway. Consisting of a 3x5 game matrix, The Expandable is a 5-reel, 10-payline slot that allows players of all bankroll levels to venture into the gold mine. As the value of coins ranges between 0.01 and 0.60, coupled with the fact that paylines cannot be configured, you can start working up a sweat in search of gold from a low limit of only 0.10 credits. If you’re feeling confident that you’ll be able to get your hands on plenty of gold, you can click the max bet button to play for a maximum of 6 credits every spin.

And don’t worry about having no signal down this gold mine, as The Expandable has been developed in HTML5 to ensure it is mobile-optimized. This means you can start digging for gold using your tablet or smartphone no matter where you are, rather than being confined to playing via desktop.

The Pay Table Isn’t So Golden

To discover how much money is on offer for digging deep inside this gold mine, simply click on the blue pay table button beneath the reels. Payouts are associated with seven of the eight symbols that feature on the pay table of The Expandable, ranging from a minimum of just 5x your line bet to a maximum of 1,000x.

Before we discuss how much each symbol is worth, we must express our disappointment at the range of symbols that the creative team at Gamomat have included. Only four of the symbols are theme-related, while the other four are playing card symbols. These playing card symbols could easily have been replaced by symbols related to gold mining, such as lanterns and gold pans.

A, K, Q and J symbols represent the low-paying playing cards that feature on the reels. Their inclusion will come as no surprise to those of you who have played Gamomat slots before, as they are included in most of the company’s online slot machines, but we are disappointed by their design. Rather than give the playing cards a gold makeover to emphasize the theme, the designers have lazily included them exactly as they appear in other releases. As you’d expect, they aren’t worth much either. A maximum of only 50x your line bet is on offer for matching any of the playing cards.

The next highest-paying symbol is represented by a pickaxe and shovel, worth up to 100x your line bet. This is followed by a mine cart filled to the brim with gold, delivering prizes of up to 250x your line bet. To secure the top prize of 1,000x your line bet, you’ll need the gold miner to appear across the same payline five times.

Increase the Value of Your Gold

The Expandable boasts a couple of very exciting bonus features to help you boost the value of your newly discovered gold nuggets. The most explosive of these is the wild symbol, represented by a stack of red dynamite sticks. Dynamite can only appear on the first, second and third reels, possessing the ability to substitute for all regular symbols. However, the biggest perk of this special symbol is its explosive powers. Whenever a stack of dynamite rolls onto the reels, it will explode and transform all surrounding symbols into wild symbols for even bigger wins.

Not afraid of losing every ounce of gold that you’ve acquired for the chance to get your hands on even more? Then you’ll want to make use of the two different types of gamble features that have been included in The Expandable. If you decide to gamble your winnings, you’ll get to choose whether to risk them on a card gamble or a ladder gamble. For those unfamiliar with such features, allow us to explain quickly. Choosing the card gamble requires you to guess whether the next card to be revealed will be red or black. If you opt for the ladder gamble, you'll need to land on the highlighted step above your current position. Just be careful not to get too greedy!

Other Gold Mines Worth Exploring

Don’t worry if the supply of gold in this mine runs out because there are plenty of alternatives for you to explore while playing at online casinos. If winning up to 20,000x your line bet sounds appealing, you’ve got to try the Gold Mining video slot developed by Roundstone International. It might not be visually impressive, but the rewards on offer for lining up dynamite, gold nuggets, lanterns and shovels will surprise you. It’s a 5-reel, 9-payline slot with low variance that attempts to recreate the atmosphere of the 19th-century Gold Rush. It also boats a couple of golden nuggets in the form of bonus features, including a reel respin feature and a pick ‘em game.

Paying a visit to the mine in Gold Miner by YoYouGaming could also prove to be very lucrative. Digging for gold here is a perilous task, which is highlighted by its higher-than-average volatility level. Nonetheless, it’s certainly a mine worth exploring due to the bonus features that can be unearthed. Golden pickaxes and shovels represent the high-paying wild symbol, oil lamps lead the way to huge scatter wins and lots of free spins, while mining carts can trigger a pick ‘em game. You could also win one of four jackpots – either the mini, minor, major or grand. So, what are you waiting for? Get digging now!

Worth All the Hard Work?

We reckon you’re going to have a very good time digging for gold in this mine, so the answer to that question must be an emphatic “yes”. Visual and audible flaws aside, The Expandable offers solid gameplay and impressive payouts worth up to 1,000x your line bet. Exploding wilds are the main reason you’ll want to work up a sweat in this mine, as there is no better sight than dynamite exploding to make surrounding symbols wild. Brace yourself for some very explosive wins!
