Hubbard
How to play Storm
- Every row and column needs three bolts and three clouds.
- Never three of the same symbol in a row or column.
- An '=' between two cells means they match; an '×' means they differ.
- Tap a cell to cycle bolt, cloud, empty. Broken rules turn red.
Your first useful move
Look for two identical symbols next to each other: a third would break the no-three rule. Then check the row and column totals to see which symbol is still needed.
