Luck Calculator
Mine a Planet Luck Calculator
Input a one-in-N chance, your Luck multiplier, and roll count. The tool models repeated-roll probability without claiming Mine a Planet's hidden formula.
Shareable result: one-in-1,000 odds at 1x Luck gives 2.47% after 25 rolls.
Model only: Mine a Planet has not published a hidden Luck formula. Use odds shown in your own UI.
What this calculator does
Mine a Planet is built around drone rolls and rare pulls. The calculator answers one practical question: if your target has a known base chance and you roll many times, what is the chance you see it at least once?
It estimates four useful numbers for players: adjusted single-roll chance, chance after a chosen number of rolls, chance after common checkpoints such as 10 and 100 rolls, and expected rolls. Use those numbers when deciding whether to roll now, save boosts, or focus on upgrade progression.
How to find your odds
Use the one-in-N value shown in the current roll UI, drone card, or event screen. If the game says an item is one in 10,000, enter 10000. If you do not have a visible number, treat the result as a planning example rather than a confirmed Mine a Planet value.
How the model applies Luck
This page uses a simple model: adjusted chance equals Luck multiplier divided by one-in-N odds, capped at 100%. That is useful for comparing scenarios, but it is not a claim that Mine a Planet uses this exact hidden formula.
Example
For a one-in-10,000 drone with 2x Luck, the model treats each roll as roughly 1 in 5,000. After 100 rolls, your chance is still small; repeated rolls improve your odds, but they do not guarantee the pull.
For a simpler example, enter base odds of 1000, a Luck multiplier of 2, and 100 rolls. The tool models that as a stronger single-roll chance than 1x Luck, then uses the repeated-roll formula to estimate the chance of at least one success.
Probability versus guarantee
Probability describes risk, not certainty. Even a high percentage can miss, and a low percentage can hit early. Expected rolls are an average across many attempts, not a schedule. If Mine a Planet adds pity rules, guaranteed milestones, or event-specific boosts, those visible rules should override this generic model.
Common mistakes
- Confusing expected rolls with a guaranteed result.
- Entering 0.01 for one-in-10,000 instead of entering 10000.
- Assuming all Luck boosts stack the same way without checking the live UI.
- Spending every boost before measuring whether upgrades would improve income faster.

Luck Calculator FAQ
What does one in N mean?
One in N means the simple single-roll chance is one success out of N attempts before any Luck scenario is applied.
Does 2x Luck halve the odds denominator?
This calculator models 2x Luck that way for planning, but Mine a Planet has not published its exact internal Luck formula.
Are Mine a Planet rolls independent?
The calculator assumes independent rolls for probability math. If the live game adds pity, guarantees, or event rules, use the visible game UI instead.
What are expected rolls?
Expected rolls are the average number of attempts suggested by the probability model. It is not a promise that the reward appears on that exact roll.
Does 90 percent probability guarantee a drone?
No. A 90 percent chance still means 10 percent of matching attempts miss in the model.
Is this the official Mine a Planet formula?
No. It is a general probability calculator tuned for Mine a Planet player scenarios, not an official Skydog Games formula.
