Hey Rollers! 🐹

This one comes straight from you.

After hearing your feedback about inconsistent win rates and frustrating Expedition outcomes, we’ve made a major update to how survival works.

The goal is simple: more clarity, more control, and more consistent results.

Let’s break it down.

⚙️ How It Works

The Survival Chance is no longer a hidden or unclear system.

It’s now built from three clear components:

  • Basic Chance (based on stats)
  • Difficulty Influence (based on Expedition difficulty)
  • Ability Influence (from Hamsters)

Together, they form the final result. Let’s go step by step.

Basic Chance

Your base survival chance is now directly tied to your Hamster’s stats.

Main changes:

  • Every Hamster starts with a minimum of 20% survival chance
  • Higher total stats significantly increase your chances
  • The scaling is now smoother and more predictable

Here’s how it looks in practice:

Stats SumSurvive Chance
5020.38%
10024.71%
15033.83%
18543.07%
20047.75%
21552.86%
22054.66%
25066.47%
27577.64%
30090%

Difficulty Influence

Difficulty is no longer just an abstract idea. It now directly affects your survival chance.

  • Lower difficulty → increases your chance
  • Higher difficulty → reduces it

The influence ranges from +5% on easiest Expeditions to -5% on hardest Expeditions

Here’s the breakdown:

DifficultyInfluence
1+5.00%
2+3.89%
3+2.78%
4+1.67%
5+0.56%
6-0.56%
7-1.67%
8-2.78%
9-3.89%
10-5.00%

This change makes your map choice part of your strategy.

Ability Influence

Abilities that grant Survive Chance are now applied directly to the final result. Main changes:

  • Abilities are now clearer and more impactful
  • You can directly calculate their effect

To keep things balanced, Survive Chance bonuses have been slightly adjusted:

HamsterOld ValueNew Value
Guile+10%+5%
Naugthy Claus+20%+10%
Plague Dancer+20%+15%

Even with these adjustments, Hamsters will still have higher win rate.

New Expeditions

Last but not least, we added two new Expedition maps: Valhalla Trail (18h) and Deep Forest (Hard) (30h), along with the key improvements you read above.

There’s more yet to come…

Our anniversary is almost there and it will bring unexpected rewards, suprises, and mechanics.

But that’s all we can say for now.

Stay tuned, and keep on mining!
