Monster’s Fortune is a 5-reel B3 slot set in Frankie’s lab, played on 40 win lines with stakes of 25p to £2 and a £500 jackpot. Its features revolve around Frankie and three Brain Jars in green, red and blue.
Frankie appears across the features. Frankie Heads award Free Spins in Power Play, a 2×2 Frankie collects prizes in Frankie’s Fortune Spins, and in Frankie’s Pot Feature he has to be zapped awake to keep it going.
Base Game and Brain Jars
Matching 3 symbols along any of the 40 win lines awards a win, and wild symbols can land on reels 2, 3 and 4.
Landing 3 or more scatter symbols in a single spin triggers Frankie’s Free Spins. The feature can also start when the Blue Brain Jar spills.

Power Play
Power Play offers a choice of Low, Medium or High Volatility Spins. Once a level is chosen, landing 2 Frankie Heads and a Free Spins Bolt on the win line awards the number of Free Spins shown on the Bolt.
Frankie’s Free Spins
During Frankie’s Free Spins, Red and Green Brain Jar symbols add to their jars, with the chance of triggering a bonus. The Red Brain Jar leads to Frankie’s Fortune Spins and the Green Brain Jar to Frankie’s Pot Feature. Each Blue Brain Jar symbol adds 1 extra Free Spin.
Frankie’s Fortune Spins
Triggering the Red Brain Jar awards 5 Fortune Spins on a 5×5 grid, with a 2×2 Frankie on the grid. Cash coins, cash pots and green potions can land, and any cash coins or cash pots that land inside Frankie’s 2×2 are awarded.
Each green potion Frankie collects increases the trail. Filling the trail makes Frankie bigger and awards additional Fortune Spins.
Frankie’s Pot Feature
Triggering the Green Brain Jar starts Frankie’s Pot Feature. You pick 1 of 4 pots, all four are revealed, and the chosen pot is awarded.
You then choose 1 of 2 levers to zap Frankie. If he wakes up, another Pot Feature is awarded, and this continues until the jackpot is won or Frankie does not wake up.
Gamble
The Gamble can be set to appear on all wins, on wins of 5x the stake, or not at all. It brings up six dials, three offering increasing cash prizes and three offering increasing numbers of Free Spins.
After you choose a dial, the dials spin. Landing in the green section awards the selected prize and lets you keep gambling for more Free Spins or a bigger win, while the red section loses the gamble and returns you to the base game. Up to 20 Free Spins or £500 can be won.
Overall
The Brain Jars connect the features. Blue starts or extends Frankie’s Free Spins, while Red and Green fill during those spins and lead to the two bonuses, where Frankie either collects prizes inside his 2×2 or keeps the pots coming each time he wakes.
