Horseshoe magnets
(Published on 28. September 2020, 17:34 by RobertBe)
The grid is made up of magnetic and non-magnetic plates. Each 1x2 magnetic plate has two symbols: one positive (+) and one negative (−). Each 2x2 magnetic plate is a horseshoe magnet with 2 positive (+) and 2 negative (-) symbols, as indicated in the example. Horseshoe magnets can be rotated (with respect to the example).
2x2 plates can be non-magnetic (neutral) as well.
Same symbols can not be horizontally or vertically adjacent. The numbers outside the grid indicate how many symbols of each kind can be found in that row or column.
Same symbols can not be horizontally or vertically adjacent. The numbers outside the grid indicate how many symbols of each kind can be found in that row or column.
Solution code: Row 9, Column 4. + and - for magnetic symbols, N for non-magnetic (neutral) symbols
