Mole in the Hole Online Slot Game

Dig deep for hidden rewards with Mole in the Hole, a 6x5 high volatility online slot packed with scatter rewards, cascading wins, and impressive max win potential.

Land 4 or more scatter symbols to blast open the Diggy-Boom Free Spins, where persistent multipliers and explosive Bomb symbols tear across the grid all the way to the biggest underground rewards.

What Is Mole in the Hole Slot?

Mole in the Hole takes you underground on a 6x5 grid powered by a scatter reward system. This adventure-themed slot puts a fearless little mole at the center of a treasure-hunting expedition where every spin can blow up into something massive.

Symbols land anywhere on the grid and create wins without needing to align on fixed positions. Matching symbols vanish after each win and fresh ones tumble in to fill the gaps. Multipliers build with each cascade, stacking momentum deep into every spin sequence.

High volatility means rewards could arrive less frequently in this slot game. If you stay around, though, rewards scale fast, especially inside the bonus rounds.

How Do You Win on Mole in the Hole?

Mole in the Hole runs four interconnected mechanics that escalate win potential spin by spin.

Scatter Reward System

Every position on the 6x5 grid is active on every spin. Matching symbols landing anywhere on the grid create a win without the need for traditional winlines. The more matching symbols you land in a single cascade sequence, the larger the reward.

This open-grid format creates far more win opportunities per spin compared to a standard winline structure. It also means every cascade has a full chance of generating a fresh combination from the newly tumbled symbols above.

Cascading Wins

Every winning combination removes the rewarding symbols from the grid. New symbols fall from above to fill those empty spaces immediately. This creates the opportunity for a chain reaction of wins from a single opening spin.

Multipliers build with each successful cascade in the sequence. The longer the chain runs, the more valuable each subsequent win becomes. This is the engine that powers Mole in the Hole from ordinary spins into big reward territory.

Diggy-Boom Free Spins

Land 4 or more scatter symbols on the same spin to activate Diggy-Boom Free Spins. The number of scatters you trigger with determines how many free spins you receive, up to a maximum of 15.

What makes Diggy-Boom special is what happens to the grid during these spins. Dug-up positions and their multipliers stay locked in place for the entire free spins round. They do not reset between individual spins. The round continues until the free spins are exhausted or the maximum multiplier threshold is reached.

Persistent multipliers are the key mechanic here. Every spin adds to a growing stack rather than resetting the board. The longer the bonus runs, the bigger the accumulated multiplier value becomes.

Even Bigger Boom

Trigger Diggy-Boom with at least one Super Scatter included among your scatter symbols and you unlock Even Bigger Boom. This enhanced bonus mode delivers the full Diggy-Boom experience with one crucial upgrade.

Even Bigger Boom starts with x2 multipliers already applied to each dug-up position at the beginning of the round. That head start means multiplier stacks reach higher values far faster than in standard Diggy-Boom. Combined with cascading wins that keep building on top, this is the mode where the largest reward totals are assembled.

Bombs Feature

During any active bonus spins, Bomb symbols can land on the grid. Bombs come in three sizes. A 1x1 Bomb covers a single position. A 2x2 Bomb covers a four-position block. A 3x3 Bomb covers a nine-position block.

Once a Bomb lands on the grid, it locks in place until every cascade from that spin fully resolves. When the cascades are complete, the Bomb explodes. The explosion clears surrounding symbols from the grid and creates additional dug-up positions. More dug-up positions means a wider multiplier footprint for the spins that follow.

Larger Bombs create larger explosions. A 3x3 Bomb detonating mid-bonus can dramatically expand the active multiplier zone and keep the chain reaction going across a reshaped grid.

Why Play Mole in the Hole Online Slot?

Mole in the Hole earns its place in the high volatility category with one standout feature: the multiplier system does not reset during free spins. Most bonus rounds wipe the slate clean on every spin. Diggy-Boom locks multipliers into dug-up positions for the duration of the round, meaning every spin compounds the growth started by the one before it.

Even Bigger Boom accelerates this further by seeding the board with x2 multipliers before free spins even begin. You enter the bonus already ahead of where standard Diggy-Boom starts, and every cascade from that point builds higher.

The Bombs Feature adds a physical dimension to the bonus action. Rather than a static grid throughout the free spins, Bombs actively reshape the playing field. A well-timed 3x3 explosion mid-sequence can open up a completely new section of the multiplier landscape and trigger a fresh wave of cascades.

The base game scatter reward system keeps every spin unpredictable and engaging. There are no dead zones on the 6x5 grid. Any grouping of matching symbols at any position can start a cascade chain at any moment.

All of that together means Mole in the Hole is a high ceiling slot that rewards patience.
