Kr67 is designed and made by IsnTech Paweł Arent.

Science data

• Isotopes, half-lives and decay modes: IAEA Nuclear Data Section, LiveChart of Nuclides (ENSDF / NUBASE evaluations). https://www-nds.iaea.org/relnsd/vcharthtml/VChartHTML.html
• Krypton-67 two-proton decay: T. Goigoux et al., "Two-Proton Radioactivity of 67Kr", Physical Review Letters 117, 162501 (2016).
• The game has two layers. The lab layer (elements, isotopes, stability, decay, fission, fusion) follows real data, with its simplifications marked in the rules guide. The alchemy layer (patterns, stacking, powers of six, flowers) is pure game mechanics, not science.
