Glow Dig is a mining-themed slot by Red Tiger. It’s a highly volatile affair with 20 paylines. While it doesn’t look that great on paper, the slot has some exciting features that’ll keep you entertained. Developed by Max Win Gaming, it comes with a unique row atop the reels for special symbols and a free spin round focused on collection mechanics.

Most mining-themed slots aren’t exactly innovative. This one aims to change that with extra prizes that appear randomly on the premium gems. They pay up to 250x the bet and can change everything up in the base game. The free spins round offers bronze, silver, gold, and epic cart prizes that’ll keep you playing.

If you’re impatient to hit all the features naturally, you can buy them for a price. Read my Glow Dig review below to learn what it’s like to play this slot.

Glow Dig is your typical mining-themed slot. As it's a Red Tiger release, you can expect great graphics and animations with a fantastic Americana soundtrack in the background. The sound effects are on-point, with clanking coins when you hit a win and the sounds of digging tools.

Symbols include rare gems as well as skulls and body parts of animals. They’re all designed perfectly, and the dim lights give off the impression of a dig site. Animations are top-notch, especially when those stacks of dynamite blow up to reveal the bonus round.

All controls are set beneath the reels for easy access. They give way to the action on the reels in the center, so in visual terms, Glow Dig’s design leaves nothing to be desired.

Before you start playing, make sure you choose a licensed and regulated casino online. Once you load the game, you must first choose a bet from the menu in the lower left corner. Bets range from 10c to $2,000 per spin, good enough for new and experienced players. Click on the spin button on the right to begin.

Per the math model, you need at least three matching symbols to win. Unlike other slots of its kind, the gems are premiums, while the animal remains pay less. The red gem is the most valuable symbol, delivering wins of 25x for five on a line. 

All premiums can randomly land with major prizes up to 250x. A special row on top of the reels can come with drill machines, mine carts, and empty carts.

• Mine carts collect all prizes from the reel beneath.
• Drill machines collect prizes from all reels.
• The empty carts do nothing.

This particular mechanic is quite lucrative and can boost your base game wins nicely. It’s the only special feature in the base game, though. If you’re looking for more significant wins, they come in the bonus round.

At least three TNT dynamite stacks landing on the reels trigger the bonus round. With each free spin, all carts and drill machines move one spot to the left. The number of free spins is not capped. The bonus round only ends when the top row displays empty carts.

All premiums and low-value symbols disappear from the reels for the bonus round. You can only land empty carts and the following prizes:

• Bronze cart: 1x-4x
• Silver cart: 5x-20x
• Gold cart: 25x to 100x
• Epic cart: 250x to 5,000x

Mine carts and drill machines collect all the prizes per the same rules as in the base game. As long as you keep landing full carts, the bonus round will continue.

You can buy the bonus round for 80x the bet. There’s also a buy option for a super free spins bonus. It costs 250x, but guarantees drill machines on the rightmost reel.

Playing Glow Dig in my real money online casino was an absolute blast! It was straightforward and tons of fun. While the title has decent bonus features, it’s not overly complex, which I liked. The cart prizes in the base game paid good rewards during my run. However, the volatility is on the extreme side, so you should be careful with your bets.

Since I couldn’t trigger the bonus round naturally, I paid 80x the bet for it. It’s a decent price, in my opinion. With all symbols removed and only cart prizes on the reels, I won 130x during my bonus session.

Glow Dig is a highly volatile slot game with 30 paylines and an RTP of 96.00%. The maximum win is projected at 5,000x the bet.

If you like mining-themed slots, you’re going to love this one. Glow Dig keeps the action down to Earth while introducing some nice features that can pay decent sums of money. The key lies in the collector mechanic associated with the carts above the reels. As long as you’re lucky enough to land full and not empty carts, you’ll do great.

Players looking for alternatives should try Big Time Gaming’s epic slot Bonanza. It’s an entirely different mining slot with the Megaways mechanic and higher wins. You can also try Drill That Gold by Pragmatic Play for a more classic experience.
