Topo Mole — Bonus Features
Topo Mole runs two bonus paths — the Dig Bonus pick round and Underground Free Spins — both feeding the depth multiplier. Here's how the 3,000x ceiling comes together.
All Features
Dig Bonus
TriggerLand 3 shovel symbols on the reels in the same spin to open the Dig Bonus pick screen.
Tunnel Wilds
TriggerA mole wild lands on any reel during base or bonus play. The mole then digs across the grid before symbols lock.
Underground Free Spins
TriggerLand 3 or more scatter symbols anywhere on the reels in a single spin to award 12 Underground Free Spins.
Mole Multipliers
TriggerActive during Underground Free Spins. Each spin advances the depth counter by 1, which in turn raises the running multiplier.
