Mole in the Hole is a mining-themed 6x5 slot game from Penguin King. Released in 2023, the game uses a pay anywhere mechanic, which means you need to land 8 or more identical symbols anywhere on the reels. They don't have to line up in any particular order, nor do they need to be adjacent to one another. The more symbols you land, the more valuable the strike.

This cartoonishly fun slot game offers high-volatility gameplay, an RTP of 95.6%, and two types of free spins bonus rounds. These Mole in the Hole bonus games can be triggered by landing Scatters and Super Scatters, or by using the handy Bonus Buy feature.
Cascading reels with multipliers make it possible to dig up multiple payouts in a single spin. When you create a winning combination, the payout is instantly credited to your balance. However, something else also happens. The symbols used to form the win vanish, and new ones replace them. If another win is created after the tumble, the process repeats.
Any square that hosts two tumbling wins receives a multiplier, starting at 2x. If another winning symbol lands in that spot, the multiplier doubles. This continues until no new cascading wins occur.

During free spins, 1x1, 2x2, or 3x3 bombs can randomly land on the reels. When they do, they lie in wait until no new cascades occur. Then, they explode, causing a fresh round of cascades with bigger multipliers.
The Mole in the Hole slot boasts a few exciting features that make the game unique. For starters, the cascading reels make it possible to experience several wins during a single round. These cascading wins are the highlights of the base game. So are the layered reels. If a square on the board sees two winning cascades in a single round, a progressive multiplier is embedded in that spot throughout the rest of the round.

Another key element of Mole in the Hole is the pay anywhere mechanic. Instead of having to land identical symbols on fixed paylines, you just need to land 8 or more identical symbols anywhere on the reels. They don't even have to be touching or adjacent.
The Mole in the Hole slot has 2 bonus games, which are Diggy-Boom free spins and Even Bigger Boom free spins. Landing 4, 5, or 6 scatters triggers 10, 12, or 15 Diggy-Boom free spins. During Diggy Boom free spins, the dug-up position and multipliers remain throughout the rest of the round. The Even Bigger Boom free spins are a little different. This is because each position is already assigned a 2x multiplier, which gives you a distinct advantage.
During free spins, 1x1, 2x2, or 3x3 bombs can randomly land on the reels. When they do, they lie in wait until no new cascades occur. Then, they explode, causing a fresh round of cascades with bigger multipliers.
The Mole in the Hole RTP rating sits at 95.6%, which is pretty standard for a Penguin King slot, even if it is slightly below the 96% average for online slot games. However, it dips a bit during Diggy-Boom and Even Bigger Boom free spins. This RTP rating is based on 10 million rounds, but it is just an average, so don't expect it to hit every single time.
Mole in the Hole is also a highly volatile slot. This means that it doesn't pay out as frequently as lower-volatility games, but each win is typically larger on average. High volatility slots are prone to cold streaks, so you need to make sure your session bankroll is large enough to comfortably endure them. You could go a couple of hundred rounds without triggering a bonus round. Plus, when you get to that long-awaited bonus, you aren't guaranteed anything.
While we can't guarantee that you'll win at Mole in the Hole, we can offer a few tips to help you get the most out of the experience.
Mole in the Hole by Penguin King and Le Digger by Hacksaw Gaming offer a similar mining theme, a 6x5 reel set, cartoonish graphics, and a 15,000x max win potential. However, there are several differences between the two games. For instance, Le Digger is less volatile, and it offers a slightly higher RTP. Le Digger also offers multipliers as large as 500x, whereas Mole in the Hole offers multipliers up to 100x. Le Digger also has three types of bonus rounds instead of two.
| Feature | Mole in the Hole | Le Digger |
|---|---|---|
| Provider | Penguin King | Hacksaw Gaming |
| RTP | 95.6% | 96.3% |
| Volatility | High | Medium |
| Bonus Trigger | 4+ Scatters | 3+ Scatters |
| Bonus Buy | Yes | Yes |
| Max Win | 15,000x | 15,000x |
| Mobile Optimized | Yes | Yes |
We recommend Le Digger to players who prefer a lower volatility rating and slightly better long-term returns. Mole in the Hole is better suited for players who want to experience Penguin King's animated feature loops and longer chain reactions.

The Mole in the Hole RTP rating is 95.6%, which is close to the industry average for online slots of 96%. This RTP was calculated over 10 million rounds.
Yes. You can buy a round of Diggy-Boom free spins for 100x, or a round of Even Bigger Boom free spins for 500x your stake size. Because multipliers are already in place, the Even Bigger Boom free spins offer a more likely pathway to the 15,000x max win.
Once two winning symbols have cascaded in a single spot during a round, a 2x multiplier appears. That multiplier doubles each time a new winning symbol cascades in that spot during the round. Multiplier values can increase to a maximum of 100x.
Mole in the Hole offers a maximum payout of 15,000x your bet. Seeing how the stakes can range between $0.10 and $30, a maximum win can be anywhere between $1,500 and $450,000.
