Overview: Wolf of London – A Darker Turn for Fish & Chips Games

Fish & Chips Games, the British slot studio known for its cheeky humor and nostalgia-driven themes, has released its second title under Yggdrasil’s YGG Champions programme. Wolf of London launched on 17 September 2026, following the studio’s debut Bus Stop Bonanza (which took a comic look at everyday British life). This new release marks a deliberate shift: instead of rainy bus stops, players enter a Victorian Gothic London of fog, gaslit streets, and werewolf legends.

The game is the second product from Fish & Chips Games as part of YGG Champions, a programme launched in June 2026 to give independent studios their own identity within the broader Yggdrasil portfolio. Wolf of London’s darker atmosphere signals the studio’s range and ambition.

Persistent Progression: A Retention Tool Gaining Traction

One of the standout features in Wolf of London is its persistent progression mechanic – the crystal collection state is saved between play sessions. This means a player can close the game and return later to find their partially completed collection still intact. This approach is increasingly popular among slot developers targeting regulated European markets, as it encourages players to return and finish what they started.

Why this matters:

Reduces the frustration of losing progress when a session ends unexpectedly.
Creates a sense of achievement over multiple play sessions, much like loyalty programmes in casinos.
Actively boosts player retention metrics for operators.

Fish & Chips Games has taken this a step further: new players begin with three Red Crystals already banked – just two short of a complete set before their first spin. This immediate head-start lowers the initial barrier and gives newcomers a reason to keep spinning.

Gameplay Deep Dive: Expanding Reels and Crystal Collection

Base Game: 5×4 with 1,024 Paylines

Wolf of London opens on a standard 5×4 reel grid offering 1,024 ways to win. But that’s just the starting point. The real action begins with Rising Moon symbols, which expand the grid by one row each time they land. Up to three additional rows can be unlocked, pushing the layout to a maximum of 5×7 reels and dramatically increasing paylines.

Free Spins and Crystal Collection

To trigger the main feature, a player must land all three Rising Moons. This converts the expanded grid into 10 free spins played on the full 5×7 layout.

During free spins, Collectible Crystals appear – but only on the expanded rows. That means the grid must be fully grown before the mechanic can even begin. This design choice forces players to “earn” the feature, making each unlock feel meaningful.

Crystals come in four colours. When a player collects five of a single colour, they complete a set and add a Super High Paying Werewolf symbol in that matching colour to every reel for all subsequent free spin rounds. This can stack across colours, increasing the win potential significantly.

Cross-Session Retention

As mentioned, incomplete crystal sets are saved when a player closes the game. This persistence applies across all four colours, making it a genuine long-term progression system rather than a single-session gimmick.

RTP, Volatility, and Win Potential

Wolf of London is available in four RTP configurations:

RTP Option	Value
Lowest	90.5%
Low	92%
Standard	94%
High	96%

Hit frequency: 20.3%
Volatility: Medium-high
Maximum multiplier: 3,095x (equals a max win of €386,875 based on a €125 stake)

This volatility profile suits players who enjoy moderate risk with the potential for substantial rewards, especially once the grid expands and crystal sets are completed.

What the Developers and Yggdrasil Say

Fish & Chips Games marketing team explained the creative direction:

“Our first game was a bus stop in the rain. This one is a fog-bound street and something on the other side of the door. Both are British, they are just different halves of it. The reels grow because we wanted players to go and find the thing, rather than be handed it on spin one.”

Phill Taylor, Head of Region – Europe at Yggdrasil, highlighted the retention value:

“Its crystal collection mechanic saves player progression across sessions, a genuine retention driver that feels natural, while expanding reels build toward a full 5×7 free spins round, backed by enough volatility to reward players with great win potential.”

These quotes underscore the deliberate design: progression that feels earned, not given, and a narrative arc that matches the dark Victorian theme.
