Every element from hydrogen to oganesson gets a rarity tier, from Common to Mythic, based on how much of it there is on Earth. Spin to see what you pull.
Each element’s tier comes from how much of it is in Earth’s crust, oceans and air. The rarer the tier, the thinner its slices, so a Mythic really is a rare pull. The winner’s pop-up shows the tier, the symbol and the atomic number.
| Tier | Which elements | Per spin |
|---|---|---|
| Common | Over about 100 parts per million, like oxygen, silicon and iron (23 elements) | 30% |
| Uncommon | 1 to 100 parts per million, like copper, lead and neodymium (39 elements) | 43% |
| Rare | 0.01 to 1 ppm, like silver, mercury and iodine (12 elements) | 11% |
| Epic | Rarer still but stable, like gold, platinum and osmium (9 elements) | 6% |
| Legendary | Radioactive, found only in traces or made in reactors, like radium and plutonium (11 elements) | 5% |
| Mythic | Made only in labs, from americium (95) to oganesson (118) (24 elements) | 5% |
Uncommon comes up most often because it has the most elements, but each Uncommon element is still less likely than each Common one.
In Entries, take elements off or add your own. In Odds & colors, give every element the same chance, or make Mythic pulls rarer still. In Settings, under After a spin, choose Remove it to draw elements without repeats, say one for each student.
