What is the Bones & Whiskers slot about?
Bones & Whiskers is set in a gothic crypt ruled by a necromancer hamster king. He has a crown, a staff with a glowing green orb, and an undead army that fits in the palm of your hand. They’re small, furry, and already dead.
The game’s big idea is simple: in Free Spins, the king’s Expanding Wild multipliers stay above their reels and keep adding up, so the longer the feature runs, the bigger the multipliers can get.
Why is Bones & Whiskers exclusive to Gamdom?
Bones & Whiskers is a Gamdom exclusive that we co-designed with Gamdom’s casino team. They worked with us on the undead hamster theme, the name, the 100,000x max win, and the key features, and we timed the launch to celebrate Gamdom’s 10th anniversary.

What did Just Slots and Gamdom say?
Gamdom’s 10th anniversary is a major milestone, and they wanted to mark it with something made specifically for their players rather than a standard release. Building Bones & Whiskers together from the first concept meant every key decision reflected their community. That’s how we want to create exclusives: side by side with our partners, for their players.
— Nick Formosa, Head of Client Strategy, Just Slots
Ten years is a special moment for Gamdom, and we wanted to celebrate it by giving our players something they won’t find anywhere else. Working with Just Slots from the start allowed us to shape the game around what our community enjoys, and we’re excited to see them take on the hamster king.
— Elise, Head of Casino, Gamdom
How do Expanding Wilds work in Bones & Whiskers?
The necromancer hamster king is the EXPANDING WILD. When he lands, he covers his whole reel and brings a multiplier of 2x, 3x, 4x, 5x, 10x, 25x, 50x, 100x, 250x, or 500x. If more than one Expanding Wild is part of the same win, their multipliers are added together.
The regular WILD, a hamster skull with glowing green eyes, substitutes for every symbol except the SCATTER.
How do you trigger Free Spins in Bones & Whiskers?
Land 3, 4, or 5 SCATTERs anywhere on the reels for 10 Free Spins. More SCATTERs give you higher starting reel multipliers (the multipliers that sit above each reel in Free Spins):
- 3 SCATTERs: 10 Free Spins, no starting multipliers
- 4 SCATTERs: 10 Free Spins, 5x on every reel
- 5 SCATTERs: 10 Free Spins, a random +10x on each reel
Land 3, 4, or 5 SCATTERs again during the feature for 3, 5, or 10 more Free Spins.
How do the Free Spins multipliers add up?
In Free Spins, Expanding Wild multipliers are collected above the reels. When another Expanding Wild lands on a reel that already has a multiplier, its value is added to the one that’s there. A reel sitting on 5x that gets a 10x Expanding Wild moves up to 15x.
When a win lands, the reel multipliers and the Expanding Wild multipliers are added together before it’s paid.
What Bonus Buys and boosts does Bones & Whiskers have?
Bones & Whiskers has two Bonus Buys, three HotSpin options, and Vortex, for when you’d rather not wait for Free Spins. Bonus Buy and HotSpin prices are multiples of your base bet (your stake per spin, before any HotSpin).
Bonus Buys
- Tomb Bonus (150x): Free Spins with 3, 4, or 5 SCATTERs at random
- Crypt Bonus (500x): Free Spins with 5 SCATTERs
HotSpin
HotSpin adds an extra stake to every spin for a better shot at Free Spins or Expanding Wilds:
- Ember (4x): more SCATTERs, for a better chance of Free Spins
- Flame (25x): more Expanding Wilds in the base game, but Free Spins can’t trigger while it’s on
- Tinder (50x): more Expanding Wilds in the base game and higher Expanding Wild multipliers in Free Spins
Choosing a Bonus Buy switches HotSpin off.
Vortex
Vortex gives you a chance to win a bonus for less than its standard cost. Pick Tomb Bonus, Crypt Bonus, or the Vortex-only Whiskers Bonus, set your wager, and spin the Vortex wheels. Every wheel has to succeed to award the bonus. If any wheel fails, the Vortex wager is lost and play goes back to the base game. New to Vortex? Read how the Vortex feature works.
