1. Player starts by clicking the "Capture Neutrons" and "Capture Protons" buttons once each
2. Starting from 1H, the player then clicks and drags one of the place marker to the corresponding isotope they created.
Ex. On first clicks, if neutrons captured = 1 and protons captured = 2, the player will move the marker to 4Li
3. If the player created a stable isotope, their turn ends. Otherwise, they will click on "Beta Plus" if above the stability line or "Beta Minus" if below the stability line
Beta Plus = Z -1, N +1. Beta Minus = Z +1, N -1
4. If the decay button outputs a 0, player does NOT decay and their turn ends. If it outputs a 1, player DOES decay and the player will move the marker to the corresponding isotope created and their turn ends
5. After player reaches the end of their turn, next player (if applicable) starts from 1H. Start next turn from the previous isotope made
6. If you create a nonexistent isotope, recapture Z and N. If you reach Fe, N capture and Beta Plus decay only
