Quickspin's Scatter Monsters is a 6x6 Pay Anywhere Cascading Wins grid-based video slot with medium volatility. Collecting symbols as "souls" awards two distinct modifiers, and the bonus round features multiplier increases of up to x20. The maximum payout is 1,493 times the initial bet. The RTP is 96.08% which is the market average.
The grid itself is a 6x6 panel that uses scatter pays to generate victories. When at least eight matching symbols appear on the reels in any position, a victory is formed, and the winning symbols are removed. New symbols will drop to replace those removed, and this procedure will continue until there are no more scatter wins. The festival is run by a medium-volatility (rated 3 out of 5) mathematical model with three RTP settings, the maximum of which is 96.08%; these values can be found on the paytable.
Other paytable data contains symbols and their respective payouts. Pay symbols are categorised by colour and category. Demons are red, vampires are blue, and undead are green. This is because each colour corresponds to a Soul Metre, which will be discussed below. For the lows, we have an Impish Vampire, a Hatchling Zombie, and a Puny Demon. For the mids, we have a Vampire, a Zombie, and a Demon. Regarding payouts, scatter wins of 8-9 of a kind are worth 0.2x to 1.5x the wager, while scatter wins of 26-36 pay 0.75x to 10x the wager. Scatter Monsters is playable on any device, with wagers ranging from 0.20 to 100 per turn, and wild symbols can substitute for all pay symbols.
When successful scatters appear, the symbols that comprise them are added to the Soul Metre corresponding to their colour. Filling the metre activates its modifier bonus;
