Double Bonk is a bonus round that begins with one wild symbol at x1 multiplier and two priority contacts. Priority contacts can push the multiplier up to x3. Hammers and rebounds add more contacts within the usual cap. Scatters may open a feature during Double Bonk. The round evaluates one final board for payment.

Tunnel Run triggers when three scatters land. It awards eight free spins and guarantees one mole symbol per spin and one contact per spin. A column that receives a contact upgrades and expands. If three contacts land in a single spin, one extra spin is awarded, with extra spins awarded up to twice.

Colony Takeover triggers when four or more scatters land. It grants three respins where wild positions and their upgrade levels persist across spins. A new wild symbol or an upgrade resets the respin counter to three. A spin without improvement uses one respin. Only the final board delivers a payout.
