Fun House Review
Fun House is built like a fairground ride. Each round starts with a Loading Run, you choose which reels to hold, and then one to four Active Runs play out. Rollercoaster symbols in those runs collect bonus prizes worth up to 250× the bet.
Loading runs and active runs
You set between 1 and 4 Active Runs per round, and the round costs your bet per run times the number of runs. More runs give more chances to land a winning combination.
After the Loading Run you pick the reels to hold. If the Loading Run itself lands five matching symbols, no Active Runs are played and you are paid the Loading Run prize multiplied by the number of Active Runs.
Fun House Features
The rollercoaster bonus
In each Active Run, three, four or five rollercoaster symbols add a bonus round to the counter at the bottom right. Only one bonus can come from each run, so a round holds at most four.
Each bonus round pays your total bet multiplied by a random value between 1 and 250.
Wild symbol
The wild substitutes for every symbol except the rollercoaster. Lines pay from left to right, and only the highest win per line counts.
RTP
The game's rules give a theoretical return of 90.5% to 93.2%, and the embedded configuration is set to 90.5%. No maximum win or volatility rating is published.
