3 Wonders Monster Pays — RTP, volatility and max win

3 Wonders Monster Pays by Boomerang Studios throws a Halloween night in the graveyard: Dracula, zombies, ghosts and demons appear among candles, blood and card suits. Random wilds carry multipliers, collected energy powers the bonus mechanics, and in the hold and win round value symbols stick in place.

The theme is classic Halloween monster horror: Count Dracula, zombies, ghosts and demons in a graveyard at night, with candles, blood splatters and card suits, all in black and blue. The monsters roam a 5×4 grid, five reels of four rows, across 50 paylines. Bets start at €0.25 per spin and climb as high as €80. Boomerang Studios released 3 Wonders Monster Pays on October 21, 2025, and the figures were last checked against the source on June 17, 2026.

Its 5×4 reels hold 50 paylines, and a payout needs matching symbols adjacent to each other from the left along a single line; with four rows per reel many lines overlap, so a single symbol often feeds several combinations. Wilds fill gaps and sometimes bring a multiplier that boosts the whole line. Bonus icons do not pay on the lines; they belong to the hold and win round. What a hit pays depends on the symbol and on the bet you choose, €0.25 at minimum and €80 at maximum.

In the base game extra wilds land at random, some carrying a multiplier, and a random multiplier can lift a win further. Meanwhile 3 Wonders Monster Pays collects energy symbols that pave the way to the special features. Bonus icons start the hold and win round: value symbols that land stick in place, the other positions keep respinning, and additive symbols add up the values on the grid. A standalone bonus game rounds out the package, and buying the bonus round skips the wait entirely.

Since the value symbols in 3 Wonders Monster Pays stick during the bonus and are topped up by respins, the other inferno slots with hold and win work in a similar way.
