Goal: Fill the grid with + and − poles so every clue is satisfied.
Rules:
Each domino (paired cells) holds exactly one + and one −, or is neutral (both empty).
Two + poles may never touch. Two − poles may never touch.
Numbers around the grid count the poles in each row/column. Red = + count, Blue = − count.
Tips: Pick a tool (Plus / Minus / Erase) then tap cells. Clues turn green when matched. Use Hint to reveal a cell, Undo to step back, Check to find mistakes.
