House of Fun is a 5-reel, 3-row, and 30-payline video slot by BetSoft casino games developer. Gameplay The Free Spins are triggered by 3 or more mystery boxes Scatter symbols anywhere on your reels. Finally, 3 or more phantasmagoric door knob symbols on an active payline unlock the Escape bonus game round . Once activated, the game will need your guidance to help Paul and Jane – the two guys who got into the House of Fun – escape from this creepy mansion. Triggered whenever a player matches three or more bonus symbols anywhere on the game board, players are instantly whisked away to a second unique set of reels. This second slot machine is a three-reel game in which matching three regular symbols or two lucky sevens awards an instant cash prize. Players are given five free spins in the bonus round, with a maximum of 20x their total stake up for grabs each spin and a 3x win seemingly the average payout. Surprising 7 also benefits from a free spins bonus that occurs on the regular game board and is again triggered whenever three or more scatter “free spins” symbols appear during a turn. As you would probably expect, the Sheriff symbol is the games wild and when landed upon will automatically multiply the size of any imminent payout it contributes towards by a total of either 2, 5 or 10 times. These boxes can be clicked on one at a time in order to reveal various free spins and multipliers – all of which can do a hell of lot for your prize total!
