NetEnt has delivered one of its most mechanically adventurous releases in years with What’s Up? Witches, a narrative-driven slot that wraps its innovation in a polished, graphic novel aesthetic without sacrificing depth or sophistication.

Asymmetrical Grid Meets Spell System

The standout feature here is genuinely different from what’s saturating the current market. Players encounter an unusual 6-reel grid arranged in a 4-6-6-6-6-4 pattern, with the bottom reel spinning horizontally to create 20,736 ways to win. It’s a clever layout that immediately signals this isn’t your standard cascade slot.

Where WUW really distinguishes itself is the Arcane Feature. Triggered when a spellbook symbol lands on the bottom row, it activates nine distinct spell effects across the main grid, each represented by a pentagram sigil with its own visual design. Some turn symbols wild in specific patterns. Others clear entire rows or expand in all directions. When multiple spells chain together with the avalanche mechanic, the grid feels genuinely alive and unpredictable.

Free Spins Bring a Second Layer of Complexity

The Free Spins feature (triggered by four or five scatters for 10 or 15 spins respectively) transitions to a different 5-reel, 5-row grid and introduces the Magic Orb system. This brings nine more distinct features into play, each randomly activated during a free spin. The Doubler multiplies existing multipliers. The Collector gathers them. The Adder boosts them. The Generator creates new ones on empty positions. It’s generous mechanic design that rewards aggressive play.

Solid Numbers for High Volatility

With a 10,180x max win, high volatility positioning, 96.03% RTP, and betting from $0.10 to $100, NetEnt has balanced accessibility with genuine win potential. The mechanics are admittedly complex, which might challenge casual players. But anyone hunting for proper excitement will find plenty here.

What’s Up? Witches represents the kind of originality that keeps the iGaming space fresh. The asymmetrical grid alone sets it apart from the avalanche saturation you see across the market right now. And the dual spell systems give it real personality and replay value. It’s bold design work from Stockholm.

What the team thinks

Sheena McAllister says:

Carl’s caught onto something genuinely significant here: NetEnt’s willingness to push asymmetrical mechanics suggests the industry is finally moving past the tired “bigger multiplier, same grid” cycle that’s plagued innovation for years. From a compliance angle, what’s particularly smart about this design is that mechanical novelty like this actually strengthens player protection narratives, since operators can credibly argue they’re offering variety and engagement rather than pure RTP chasing. That said, I’d have liked to see Carl dig deeper into whether these nine spell effects create genuine strategic choice or if they’re largely cosmetic layers over conventional payout structures, because that distinction matters enormously when regulators assess whether a game is genuinely innovative or just complexity theatre.
