There’s a specific niche of slot themes that balances between cute and slightly unnerving, and Diamond Mole fits right in. Developed by Backseat Gaming (a partner studio of Hacksaw Gaming), this game takes a look at the underground world of moles, although the actual gameplay stays surprisingly surface-level. It’s a Cluster Pays slot that pairs a dirt-heavy aesthetic with a volatile math model.
We decided to test Diamond Mole to see if the combination of sticky wilds and exponential multipliers actually results in the massive wins promised, or if it just digs a hole in the balance. Here is a breakdown of what we found after putting the game through its paces.

Diamond Mole Overview
Diamond Mole is built on a 6×6 grid using a Cluster Pays mechanic. Instead of traditional paylines, you need to connect at least 5 matching symbols horizontally or vertically to form a winning cluster. The betting range is standard, allowing wagers from $/€0.10 up to $/€40 per spin.
- Developer: Backseat Gaming (partnered with Hacksaw Gaming)
- Theme: Nature/Animals (Moles)
- Grid: 6×6 Cluster Pays
- RTP: 96.31% (default)
- Max Win: 25,000x
- Volatility: High
The visual design is straightforward. Despite moles being underground creatures, the game setting remains above ground, surrounded by rocks and turf. The symbols include low-paying 10-A royals and higher-paying thematic items like shovels, lanterns, stopwatches, and the moles themselves. The game uses a tumble mechanic, meaning winning symbols vanish and new ones drop down to replace them, potentially creating chain reactions.
How the Game Plays in Real Sessions
Playing Diamond Mole feels like a exercise in patience punctuated by sudden, aggressive bursts of activity. The base game relies heavily on the tumble mechanic. In the early stages of a session, you will likely see plenty of dead spins or small, insignificant wins that don’t cover the bet cost. The 5-symbol requirement for a win isn’t hard to hit, but the payouts for small clusters (0.1x to 1x) are negligible without multipliers involved.
The core of the experience revolves almost entirely around the Diamond Wilds. When these land, they are sticky and come with a 1x multiplier. If they are part of a win, that multiplier doubles. This is where the game’s “hook” lies. In dry streaks, the game can feel monotonous because nothing happens without those wilds. However, when a few wilds land and the tumbles connect, the recovery potential is significant. The exponential growth (doubling rather than adding) means a win can go from nothing to substantial in a single sequence, but these moments are rare.
Diamond Mole RTP and Volatility in Practice
Theoretically, Diamond Mole offers an RTP of 96.31%, which is slightly above the industry average. However, the volatility is high, and this was very apparent during testing. The “observed variance” matches the developer’s description—this is not a game designed for steady, small returns.
In practice, this means your balance is likely to trend downward for extended periods. The game is designed to drain the bankroll while you chase the specific condition of sticky wilds connecting with high-paying symbols. The risk is substantial; you are essentially paying for the opportunity to hit a multiplier sequence. Players should approach this with a skeptical mindset regarding the hit frequency. Do not expect the RTP to save you in a short session.
Diamond Mole Bonus Features and Free Spins
The bonus features in Diamond Mole are simple but volatile. There are two main bonus rounds, triggered by landing scatters.
The Diamond Trail (3 Scatters):
This awards 10 free spins. The key difference from the base game is that you are guaranteed 3 Diamond Wilds on the first spin, and all Diamond Wilds remain sticky for the duration of the round. This is the “standard” bonus. It usually returns low-to-medium results unless you get lucky with symbol placement early on.
Pursuit of Diamonds (4 Scatters):
This is the upgraded bonus, also awarding 10 spins. Here, you get 4 guaranteed Diamond Wilds on the first spin, and critically, all wilds start with a 2x multiplier instead of 1x. This feature is significantly more potent but much harder to trigger naturally.
Feature Buys:
The game allows you to buy into the features directly.
- BonusHunt FeatureSpins: Costs 3x the bet for a higher chance to trigger a bonus.
- The Diamond Trail: Costs 150x the bet.
- Pursuit of Diamonds: Costs 500x the bet.
The 500x price tag for the “Pursuit of Diamonds” indicates just how top-heavy the payout potential is. Buying the features is extremely risky. The 150x buy can easily return less than 20x if the clusters don’t connect with the wilds.

Degenious Slot Rating
Diamond Mole is a “one-trick pony,” but it’s a good trick if it lands. The gameplay loop is repetitive until the multipliers kick in.
- Gameplay: 3/5 – Smooth but reliant entirely on one mechanic.
- Bonuses: 4/5 – High potential, especially the upgraded version.
- Volatility: 5/5 – Very high variance; expect dead streaks.
- Fairness: 4/5 – Clear rules and decent RTP.
- Overall: 4/5 – A solid choice for players who like high-risk, multiplier-focused math models.
