Digging Frenzy

Digging Frenzy Overview

Digging Frenzy is a gold-mining video slot from Kalamba Games, released on 12 November 2026. It runs on 5 reels and 3 rows with 243 ways to win, and it packs a lot into that compact grid: a Bonus Wheel, four Cashpot prizes, wild symbols, a Free Spins Bonus with persistent upgrade frames, and a three-level BuyBonus.

The base-game theoretical payout is 93.92%, and the three BuyBonus levels pay back 93.95%, 93.97% and 94.47%. Kalamba rates the volatility at 6 out of 10 (medium), the hit frequency is 22.8%, and the maximum win is 10,100x the bet. As with all Kalamba releases, casinos can run other RTP versions, so check the game rules at the table where you play.

Down in the Mine

The reels sit in a timber-framed shaft, with a mine cart on rails running above them. Behind the grid, a glowing orange tunnel is lined with piles of gold and blue crystals. A bearded miner in a hard hat is the face of the game, and the same character appears on the Bonus symbol.

The four Cashpot prizes are stacked on a board to the left of the reels, so the targets are always in view. Above the grid, a row of grey rocks and a “+3 Spins” sign track the extra-spin counter during the free spins. The screen stays bright and busy, and a Turbo option is available from the side menu.

Symbols and Ways Pays

Low-value symbols are the card ranks 10, J, Q, K and A in worn stone-and-wood frames. The premium symbols are mining gear: a red dynamite bundle, a blue lantern, a green pickaxe, a purple shovel and a coil of rope. Wins pay from the left on matching symbols across consecutive reels, and with 243 ways, only the best combination for each symbol is paid; the pays for different symbols are added together.

The Wild is a sparkling diamond. It replaces all symbols except the Bonus and Extra Free Spins symbols, so it helps build ways without ever touching the feature triggers.

Bonus Symbols and the Bonus Wheel

The miner Bonus symbol acts as a scatter. When 3 or more land anywhere in the base game, the Bonus Wheel is always triggered. It can also start on a spin with just one or two Bonus symbols, which is the “Digging Frenzy spin” – a small surprise that keeps even quiet spins interesting. The banner under the reels reads “Any Bonus symbol may trigger the Wheel feature”, and it means it.

The wheel has two kinds of segments:

• Cashpot prizes: Mini 10x, Minor 100x, Major 1,000x and Grand 5,000x the bet,
• Free Spins Bonus variants: 5, 10 or 15 initial free spins.

If the wheel was started by one or two Bonus symbols and lands on a Free Spins segment, up to 3 empty positions turn into Bonus symbols before the round begins, which gives the bonus a head start.

Free Spins Bonus and Bonus Frames

This is where the name of the game comes from. Before the first spin, a level 1 Bonus Frame is placed on every position that holds a Bonus symbol, and on the neighbouring positions to the left, right, above and below. A position that already has a frame is upgraded by one level. The frames stay in place for the whole round, and only one frame can sit on a position at a time.

There are three levels, and each one pays a different set of rewards when the free spins end:

• Level 1: from 0.5x up to 2x the bet,
• Level 2: from 2x up to 8x, plus the 10x Mini Cashpot and the 100x Minor Cashpot,
• Level 3: from 8x up to 250x, with the 10x Mini, 100x Minor, 1,000x Major and the 5,000x Grand Cashpot in the mix.

Each time an Extra Free Spins symbol lands, it adds a level 1 frame (or upgrades an existing one, and a level 3 frame pushes a different frame up instead). Once the last spin is played, every frame turns into its reward at the same moment, and the player is paid the sum of all of them. With the whole grid covered in frames, that final reveal is the biggest moment of the game.

Extra Spins Counter

During the bonus, every Extra Free Spins symbol is added to a counter. Every 3 symbols collected award 3 additional spins. The “+3 Spins” sign above the reels shows this, and the round can keep growing. In a 15-spin bonus we ran, the counter moved from 15 to 18, then 21, then 24 spins. Free spins pay on the bet that was active when the round was triggered.

BuyBonus

The shopping-cart button opens the BuyBonus menu with three levels. At a bet of 2, they cost:

• Level 1: 5 free spins for 62 (31x the bet),
• Level 2: 10 free spins for 104 (52x),
• Level 3: 15 free spins for 152 (76x).

The round starts immediately, and the BuyBonus pays are based on the bet shown right before the purchase. Level 3 gives the longest runway for the frames to build up, and it also has the highest theoretical payout of the three.

Who Is It For

Digging Frenzy suits players who like a feature that builds through the round rather than a single big trigger. The base game keeps moving with a 22.8% hit frequency, and any Bonus symbol can bring the wheel into play. The real upside sits in the frames: a few level 3 frames at the end of a long bonus can reach the Major or Grand Cashpot, which is how the game reaches its 10,100x ceiling. If you prefer to test it first, the free demo above lets you try the wheel, the frames and all three BuyBonus levels without any risk.
