Mad Scientist: Breaking Beakers - Hold & Win

Released on March 27, 2025, Mad Scientist: Breaking Beakers – Hold & Win is the latest spin on the classic Hold & Win format designed by BetSoft casino software.

Built with high volatility and a max win potential tied directly to how you perform in the bonus round, it’s a game that favors players looking for a bit of unpredictability.

The theme leans into the chaos of a cartoonish science lab, with a few fun mechanics thrown into the mix to keep things from getting repetitive.

Theme and Symbols

This slot takes place in the world of Dr. Walter Prescott—a high-energy scientist who seems to enjoy smashing glassware more than anything else. Visually, it’s a colorful take on the “mad lab” idea: glowing liquids, bubbling beakers, and a playful interface.

It doesn’t try to reinvent anything design-wise, but everything looks polished and fits the theme nicely. The animations are smooth, and the visuals keep the vibe light and fun without going overboard.

Betting Options and Special Features

The game runs on a 5x4 setup with 10 fixed paylines. Since it’s high volatility with a 19.98% hit rate, you’re looking at less frequent wins but potentially bigger ones when they land. It’s the kind of game where pacing your spins pays off.

In the base game, you’ll come across Mystery Symbols that are locked in before each spin. Once the reels move, these all transform into the same symbol—great when they show up in a group. There are also Expanding Wilds, which can take over whole reels and help turn a slow round around fast.

The main attraction is the Hold & Win Bonus, which kicks in when you land six or more Beaker symbols. You start with three respins, and the beakers fall downward on the grid. Clearing a full row resets your respins back to three, giving you more chances to rack up prizes.

There are also three special Beaker types that that enhance the bonus round:

• ALL Beaker collects all visible values.
• CROSS Beaker pulls in values from its entire row and column.
• EXTRA Beaker boosts the value of any Beaker it touches.

Conclusion

If you’re already a fan of Hold & Win slots, Mad Scientist: Breaking Beakers offers just enough twists to keep things fresh. The beaker modifiers give the bonus round more variety than you’ll find in similar titles, and the Mystery Symbols and expanding Wilds keep the base game engaging too.

Compared to Betsoft’s other online slots like Coins of Ra or Golden Destiny, this one feels more interactive, especially in how symbols behave during the bonus. It’s a good fit for players who enjoy the mechanic but want a bit more movement and unpredictability along the way. Casual players might enjoy the light-hearted theme, while more experienced ones will probably stick around for the bonus mechanics.
