It's alive — and it's ready to pay big. 3 Wonders Monster Pays is the second entry in Boomerang's "3 Wonders" series, this time set in a spooky monster-themed world where a mad professor and his creations have become symbols of unpredictable luck. Any spin can awaken the monster within — and when it does, the Professor or the Woman transform into Wilds right on the grid.
The slot runs on a non-standard 5×4 grid with Medium volatility — the only slot in this batch sitting at plain Medium. RTP comes in three operator-dependent values: 96.0%, 94.0%, or 90.5%. The bet range here is exceptionally modest, from €0.25 to €15, making this the most accessible entry point in the batch. The win ceiling is €150,000, and the max multiplier reaches x10,000.
✔️ Players on a smaller budget — bets from €0.25, capped at €15
✔️ Fans of Halloween monster themes with quirky characters
✔️ Those who appreciate a medium-volatility Hold & Respin mechanic with three options
❌ €150,000 Max Win and a €15 max bet — not built for high rollers
Grid: 5×4 · RTP: 96.0% / 94.0% / 90.5% · Max Win: €150,000 · Max Multiplier: x10,000 · Bet: €0.25-€15 · Feature Buy-in: ❌
| 🧟 Professor/Woman → Wild At any point in the game, the Professor and Woman symbols can give in to the inner monster and turn into Wilds, creating unexpected winning combinations. | ⚡ Hold & Respin Any Scatter activates the bonus Hold & Respin mode, giving access to one or all three features simultaneously. |
| 🎁 COLLECT / UPGRADE / BIG PRIZE Three Hold & Respin options: COLLECT gathers all prizes from switches and electricity balls; UPGRADE improves surrounding prizes on switches; BIG PRIZE awards up to 10x the total bet. | 🔌 Switches and electricity balls Prize-carrying game elements in Hold & Respin mode — switches hold monetary wins, while electricity balls activate additional mechanics. |
In the base game, the Professor and Woman symbols occasionally transform into Wilds, adding chaos and unpredictability to every spin on the 5×4 grid — exactly the spirit a true monster experiment demands.
The real lab explosion happens in Hold & Respin: when all three features fire simultaneously (COLLECT + UPGRADE + BIG PRIZE), the chance to approach x10,000 and the €150,000 ceiling is at its highest.
| ✅ Pros - Lowest max bet in the batch (up to €15) - Medium volatility — the only plain Medium in the 2025 batch - Three Hold & Respin options in one bonus mode - Charismatic monster theme - x10,000 Max Multiplier at accessible bet sizes | ❌ Cons - €150,000 Max Win — second lowest in the batch - €15 max bet — closed to high rollers - Three RTP values — conditions vary by operator - No Feature Buy-in |
