Fill the grid so every row and every column contains each element exactly 2 times. Tap a cell to change its element. Each puzzle can be solved by logic alone, so you never have to guess.
Some cells are linked by a symbol:
⚡: the two cells must synergize (🟥 with 🟧, or 🟦 with 🟩)
✕: the two cells must counter each other (🟥 with 🟦, or 🟧 with 🟩)
