Keep the sun shining bright.
Combine protons and neutrons in just the right way to make helium and release energy. It's called fusion, and it's what makes the sun burn so hot for so long.
How to play:
Combine, swap, and complete reactions for points!
- Combine particles that are across from one another on the game board. Push the particles across the board to make reactions happen.
- The order matters: not all particles will combine. You have to match the right particles to keep the reaction going. See the chart for the fusion reaction steps.
- If you want to combine particles that aren't across from each other, swap particles with their neighbors. But these swaps are limited. Use them wisely! Each time you combine two helium molecules, you complete the reaction and earn 1 point and 1 swap.
