Rollers, Jack O’Mine is ready to make you lose your head.
From October 20 to 26, welcome the final member of The Night Shift Set.
This pumpkin-headed Hamster arrives with a new Overcharged Ultimate with up to +75% Extra Loot, and the brand-new Skip Rest Chest Passive Ability.
Remember SOLaire and Lady Minerra?
They’ve been waiting for one last member to join their spooky crew. Now, the Night Shift reaches its final chapter!
Meet Jack O’Mine, Your New Halloween Hamster
Don’t let his pumpkin head fool you, Roller. Jack O’Mine knows how to make the most of every Expedition!

This new Hamster brings a combination of abilities designed to help you collect more rewards and manage your Expeditions.
Here’s what Jack brings to your team:
| Parameter | Basic | Passive Abilities |
Overcharged Ultimate Ability (NEW) | Charging |
| 💪 Strength | 60 |
Skip Rest Chest (NEW) Influencer +20% Overtime Duty +25% | Extra Loot | 18 / 24 / 30 points |
| ❤️ Health | 70 | |||
| 🍀 Luck | 90 |
Jack O’Mine’s Overcharged Ultimate: Extra Loot
Jack’s Overcharged Ultimate increases the Extra Loot received from an Expedition.
Unlike a regular Ultimate, an Overcharged Ultimate has three charge Tiers. You can activate it as soon as Tier I is completely charged or keep charging Jack to unlock a stronger effect.
| Tier | Effect | Charge Required |
| Tier I | +25% Extra Loot | 18 points |
| Tier II | +50% Extra Loot | 24 points |
| Tier III | +75% Extra Loot | 30 points |
How does it work?
Every hour of an Expedition’s original duration gives Jack 1 Charge Point. Once you reach 18 points, you can activate Tier I or keep charging to unlock a higher Tier.
For example, if Jack has 24 Charge Points, you can activate Tier II and get +50% Extra Loot on your next Expedition.
But if you want the maximum bonus, wait until you reach 30 points and activate Tier III for +75% Extra Loot!
Just remember a few important rules:
- Only fully charged Tiers count: Partial progress toward the next Tier won’t increase your bonus
- Tier bonuses don’t stack: Tier III gives +75%, not the sum of all three Tiers
- You must activate the Ultimate manually before your Expedition
- Once activated, you can’t cancel it or continue charging
- After the Expedition, your Charge Points reset to zero
- Speed-Ups and Expedition Time reductions don’t affect the Charge Points you earn
And here’s a little treat: When you first get Jack O’Mine, his Overcharged Ultimate comes fully charged at Tier III!
Meet Skip Rest Chest, Jack’s New Passive Ability
Your Hamsters work hard on Expeditions, but even the toughest ones need some rest.
What if you could help them get back to work sooner?
Meet Skip Rest Chest, Jack O’Mine’s brand-new Passive Ability!
When he successfully completes an Expedition, this ability adds a special chest containing Energy Drink to the next Expedition.
This new item allows you to skip part of a Hamster’s Rest Time, helping you prepare for your next adventure without waiting as long.
And there’s one more thing, Roller: Jack O’Mine is currently the only way to obtain Skip Rest Chests!
More ways to collect them will arrive later.
Keep in mind that this Passive Ability works only after a successful Expedition. So make sure Jack is ready for the challenge!
