Ore chance calculator
Pickaxe, luck, and rock block drop odds.
What ore chance is
See drop odds for ores on each rock with pickaxe power and luck, rock luck, spawn ranges, achievement luck steps, and optional buffs (race, potions, totem, weekend).
Mineable rocks: 1/24. Total luck: 0.0%. Static drop labels live on the ores page.
Luck buffs
How to use
Pick a pickaxe, add rune luck and buffs, optionally filter by ore, then expand rock rows.
- Select a pickaxe. Power decides if a rock is mineable. Luck feeds total luck with your buffs.
- Add rune luck and buffs. Type rune luck %, cycle Achievement steps, and toggle Angel race, potions, totem, or weekend as needed.
- Optional ore filter. Filter to rocks that can drop a chosen ore so you can compare only relevant nodes.
- Expand a rock. Open a block to see base chance, after rock luck, and min/max spawn chances (1 − (1 − p)^k).

Why: Shows how buffs move rare odds after rock luck and spawn range.
Weekend boost on Peak crystals
Try: Toggle Weekend (+100%), leave other buffs off, open Large Ice Crystal.
Why: Isolates the weekend multiplier before you stack more luck sources.
FAQ
What does rock luck mean?
Rock luck multiplies the per-spawn base chance (for example 1/2000 with ×50 becomes 1/40 before pickaxe luck).
Min vs max spawns?
Rocks can drop a range of ore spawns. Min/max show the chance of seeing that ore at least once across k spawns: 1 − (1 − p)^k.
Why is a rock red / not mineable?
Your pickaxe power is below that rock’s requirement. Upgrade the pick or pick a softer node.
Ore chance vs ores page?
