Mole Digger 2 by Play’n GO Slot Overview

Mole Digger 2 by Play’n GO continues the mining series established by Mole Digger, bringing Mine Cart cash collection and gem-driven enhancements into its underground setting. Wooden rails, cartoon miners and glowing gems create a colourful contrast against dark rock walls and warm golden details.

Mine Carts collect cash values from the reels above them, while coloured gems add, copy, boost or collect values in Hold’n Win. The maximum win is 10,000x the bet, and BonusTiime rates the volatility High. Explore the free demo on BonusTiime with no deposit or account needed.

Mole Digger 2 Slot Specifications

5×4 with 25 paylines keeps the playfield straightforward, while the fixed-line format supports clear online slot gameplay.

RTP (Return to Player)

The screens of this Play’n GO slot publish no RTP: the paytable, the game rules and the settings panel were read in full and none of them gives a figure. BigWinBoard lists five operator versions, 96.20%, 94.20%, 91.20%, 87.20% and 84.20%, and the specification table shows the highest of them; the version in play depends on the casino.

Volatility

Neither the game screens nor Play’n GO publish a volatility rating; BigWinBoard rates it Medium/High and BonusTiime rates it High, which points to bigger swings and a more uneven pace between base-game results and feature hits.

Max Win

The max win is 10,000x the bet.

Mole Digger 2 Slot Features

Mine Cart, Wilds, Gems, Burst Gems, Hold’N Win, and the GO Ultra toggle shape Mole Digger 2 into a feature-led Play’n GO slot with collection, conversion, and bonus-layer interactions.

Mine Cart

One or more Mine Carts can land under the reels on any spin. When they appear, every cash value directly above them gets collected, turning the lower track into a simple but important collection lane. This mechanic keeps base-game spins active even before any bonus triggers.

Wilds

Wilds can land on every reel in the Base Game, and they substitute for all symbols except Gems. That makes them useful for completing ordinary line wins without interfering with the gem system. Their role is straightforward, but they still matter because they support the regular payline structure.

Gems

Gems create the game’s main bonus path. Landing at least 6 single-coloured Gems triggers the Hold’n Win, and at least 1 Burst Gem also triggers it. If Red, Pink, Teal, Green or Blue Gems fail to trigger it, the corresponding pot collects them for a chance to start the feature.

• Yellow Gem: awards a random base-game value when collected by the Mine Cart.
• Red Gem: awards a mystery enhancement value in Hold’n Win.
• Pink Gem: adds Yellow Gems and sums their values.
• Teal Gem: copies the highest Gem value in the reels.
• Green Gem: boosts all cash values with a chosen random value.
• Blue Gem: collects all cash values in view.

Burst Gems

Burst Gems are multi-coloured Special Gems that trigger the Hold’n Win as soon as they land. Their key twist is that the triggered Hold’n Win inherits all the enhancements of the Gems that make up the Burst Gem. That gives this feature extra depth compared with a standard instant trigger.

Hold’N Win

Hold’N Win starts at 3 Re-Spins, and landing any Gems resets the counter. Feature Gems are awarded before any Re-Spin, so the feature can build value across the round. Cash Pots can only be won here, and filling all reels awards the Grand Cash Pot.

• Mini: 15x the total base bet.
• Minor: 25x the total base bet.
• Major: 50x the total base bet.
• Grand: 500x the total base bet.

GO Ultra

GO Ultra is a toggle for the Base Game that you can switch on when the game is idle. It cannot be changed during an active feature. When active, it adds enhancements for an extra 50% of the total bet, and it can improve pot values and gem combinations.

Mole Digger 2 Slot Review

Mole Digger 2 leans into a mining look with cartoon miners, rail carts and glowing gems set against dark stone. The identity comes from the way the mine cart lane and feature pots sit on the screen together, giving the layout a busy, mechanical feel rather than a purely decorative one.

The game’s main hook is the Hold’n Win system, backed by Mine Cart collection and the GO Ultra toggle. The 10,000x ceiling and the High rating given by BonusTiime point to clear swing potential, while Mine Carts collect cash values from the reels above them. That makes the structure more feature led than explosive.

Mole Digger 2 reserves its Cash Pots for Hold’n Win, where filling all reels awards the Grand Cash Pot. The 96.20% listed by BigWinBoard is the highest of the five operator versions, yet the real appeal sits in the gem interactions and the 5×4 grid with 25 paylines. It is decent, not transformative.
