The Next Evolution in Core-Inspired Machines
In House of Fun’s Rock ‘N’ Troll, players land symbols during base game spins to deplete a boss’ health meter. As players spin, the boss randomly drops hazards that block symbols from landing in certain reel positions—but landing a special symbol turns these hazards into wilds. Together, these mechanics make base game spins feel like a dynamic back-and-forth battle.
To incentivize players to defeat the boss, the machine offers a series of respin bonuses at milestones on its health meter. Each milestone adds a new enhancement for respins, and defeating the troll awards a jackpot pick’em—providing a varied bonus progression that helps sustain engagement.
