Setup and opening position
A 4×2 board is split into four vertical dominoes. Each slot can be + over −, − over +, or neutral; clues at the row and column margins state the required positive and negative totals.
Magnets
Assign all four dominoes to the unique solver-verified orientation or neutral state that satisfies every count and adjacency rule.

How to play
Assign all four dominoes to the unique solver-verified orientation or neutral state that satisfies every count and adjacency rule.
- A 4×2 board is split into four vertical dominoes. Each slot can be + over −, − over +, or neutral; clues at the row and column margins state the required positive and negative totals.
- A magnetic domino contains one positive and one negative pole, while a neutral domino contains neither. Row and column totals must match their separate + and − clues, and equal non-neutral poles may not touch orthogonally.
- Assign all four dominoes to the unique solver-verified orientation or neutral state that satisfies every count and adjacency rule.
Strategy tips
- Use any zero column clue to force a neutral slot, then combine the remaining column totals with the two row totals before checking neighboring pole conflicts.
- Meeting the total number of poles is not enough: positive and negative counts are separate, and identical poles may not touch across domino boundaries.
- Recount each row and column by sign, then scan every horizontal and vertical neighbor pair for equal active poles.

Rules, scoring, and strategy
Magnets is a complete browser implementation with its own versioned rules profile. Orient or neutralize four vertical domino slots to satisfy pole counts without adjacent equal poles.
Legal moves and game flow
A magnetic domino contains one positive and one negative pole, while a neutral domino contains neither. Row and column totals must match their separate + and − clues, and equal non-neutral poles may not touch orthogonally.
Winning and terminal positions
Assign all four dominoes to the unique solver-verified orientation or neutral state that satisfies every count and adjacency rule. Recount each row and column by sign, then scan every horizontal and vertical neighbor pair for equal active poles.
Practical strategy
Use any zero column clue to force a neutral slot, then combine the remaining column totals with the two row totals before checking neighboring pole conflicts. Meeting the total number of poles is not enough: positive and negative counts are separate, and identical poles may not touch across domino boundaries.
