Polarity Grid
Tap a charge. Opposites annihilate. Twelve taps per run.
Polarity Grid is a one-verb logic puzzle played on a five-by-seven field of positive and negative charges, all face up from the start. Tap a charge and every opposite in its row and column is dragged inward and annihilated, each line running until a matching charge stops it. Nothing is hidden, so the difficulty lies entirely in reading the board.
How Polarity Grid plays
One verb, deep board reading
Because every charge is visible, there is always a best tap available — and always the risk of taking a worse one. The skill is spotting the tap that clears the most before you commit to it.
Twelve taps, earned back
A run starts with twelve taps. Clear eight or more and the tap is free; clear an entire row and column at once and it pays back more than it cost. Those refunds are how a good run stretches well past its budget.
Three missions above the board
Three missions sit over the grid at all times. Finishing one pays a shard and hands taps back, and the next of its kind asks for a little more. A mission you keep missing eases off after a few runs.
A new challenge every day
A daily challenge turns over at midnight and is the same for everyone. Shards from missions and challenges buy colour themes for the two charges; they are cosmetic and nothing touches gameplay.
Offline, no accounts
It loads straight into the grid, plays fully offline, and asks nothing of you — no sign-in, no tutorial wall.
