Overview
The 3 Wonders Series is a set of slots made by Boomerang Studios, a partner studio of Yggdrasil. Each game has a completely different theme, such as Lunar New Year, a monster lab, a zoo, sea fishing, or Halloween witches. But they all share the same rule: three different features are hidden inside the bonus, and scatters wake them up one by one. Yggdrasil calls this structure the “3 Wonders™ mechanic” and uses it as a trademark.
The first title was 3 Wonders New Year Carnival, released on January 28, 2025. It was a Yggdrasil Masters game, built by Boomerang with Yggdrasil’s development tools and released together with ReelPlay. Five more games in the same style followed through October 2026.

How does the 3 Wonders mechanic work?
The basic flow has three steps.
- Three features are set in advance. Three devices, such as a lantern, a door, or a pumpkin, hang above or beside the reels, and each holds a different bonus feature.
- Scatters open the devices one by one. Each scatter wakes one device, so 1, 2, or 3 features turn on depending on how many scatters land and where.
- Active features apply to the bonus together. The bonus starts even if only one feature is on, and if all three turn on at once, their effects stack for the best shot at the biggest win.
Which bonus the features attach to differs by game. New Year Carnival, Zoo, and Witches Wild Fortune use free spins, Monster Pays uses Hold & Respin, and Catch and Santa On The Beach attach all three features to a short bonus round called “Super Spins.” Most games also support bonus buy.

How the games differ
- Layout: Most are 5 reels by 3 rows, but Monster Pays is 5 reels by 4 rows. Witches Wild Fortune uses 243 ways, and Zoo uses 25 paylines.
- Volatility: According to Yggdrasil’s official information, Monster Pays is medium, Santa On The Beach is low, and the rest are medium-high.
- Bonus entry: In Witches Wild Fortune, 3 scatters start 12 free spins. If more scatters land during free spins, 8 more spins are added and features that were still off can turn on.
- Base game features: New Year Carnival has a Hold & Respin triggered by 3 coins, and Monster Pays has a separate feature that turns the professor and woman symbols into wilds.
Different games from 10,000 Wonders
The similarly named 10,000 Wonders MultiMax (July 2024) and 10,000 Wonders Big Bang (December 2025) are Arabian-themed games from ReelPlay. Their core is up to 10,000 ways and consecutive wins, so they have nothing to do with the 3 Wonders mechanic of opening three features. You can find both in the Yggdrasil free slots list.
