Another candy slot? I know what you’re thinking. But Sweet Lab manages to mix up the formula by taking you right inside the factory, and the real ingenuity here isn't the theme; it's the game's engine.
The whole experience is built around a big 7x7 grid and Cascading Reels. A lively jazz track keeps things upbeat, but the main event is watching those symbol clusters pop and trigger chain reactions.
Sweet Lab plays out on a 7x7 grid. Forget traditional paylines; you're looking for clusters of matching symbols landing together. Once you do, they pop and vanish, letting new symbols tumble down to fill the empty spaces.
This cascade effect is the heart of the game.
That chain reaction can continue for up to 100 consecutive cascades from a single spin, creating a steady and engaging flow of play.
You can set your stake from 0.10 up to 5.00. The game has a 94.49% RTP with medium volatility. In practice, that translates to a fairly consistent hit frequency.
You’ll likely see a steady stream of smaller combinations rather than long gaps between them, a pace that’s well-suited for managing your session and playing within a set budget.
There isn't a typical free spins bonus here. Instead, Sweet Lab has a Hold & Win style feature that kicks in after a particularly long cascade of 52 or more symbols.
When it triggers, the grid wipes clean. You get three spins to land special hit symbols. Each one that lands sticks in place and, better yet, resets your spin count back to three.
The feature continues until you either run out of spins or manage to fill all 49 spots on the grid.
The key to unlocking the extras is the Feature Meter, an element you'll find yourself keeping an eye on. It fills up as you collect symbols within a single cascade, triggering different modifiers along the way.
Position Multiplier: Collect 9 symbols in a single cascade, and multipliers will appear on the empty grid spaces left behind. If a new symbol drops into that primed spot and creates another win, its value gets multiplied. It's a clever mechanic that rewards longer chain reactions.
Popping Wilds: Hitting 14 symbols in a cascade sequence throws four to seven random wilds onto the grid, which can help connect new clusters.
Popping Sweets: This one requires 26 symbols to activate. The game will pick one symbol type and remove it completely from the grid for that cascade, leaving more room for other symbols to connect.
You can play Sweet Lab right here at PokerStars Casino, on both desktop and mobile. It runs perfectly on smaller screens.
Portrait mode works great, as it gives you the best view of the whole 7x7 grid. The important stuff, like the Feature Meter, is always easy to see.
Most slots that commit to a theme stick to it, but Sweet Lab makes a curious choice. The lower-value symbols are exactly what you'd expect: jelly beans and other sweets that fit the factory setting.
Then it throws a curveball.
The higher-value symbols are classic BARs and 7s. It's a strange mashup of a new-school grid slot and an old-school machine, but it certainly gives the game a unique look. You'll also see Rainbow Candy Wilds that substitute for any other symbol.
At its core, Sweet Lab is all about the satisfying chain reactions from its Cascading Reels. The constant action, driven by the Feature Meter, makes for an engaging session.
The limited bet range suggests it’s not for the high rollers, but it’s a solid choice for players looking for steady, feature-driven entertainment.
It’s a great-looking slot for a casual session. Just remember to always play within your means, set limits for yourself, and know when it’s time to take a break.
