"[[File:Magnets-01-sam.jpg|200px|thumb|right|'''Magnets''' example, From: 23rd WPC Instrucion Booklet © 2014, UK Puzzle Association]] '''Magnets'''(待定中文名:磁鐵放置) 。 ==Rules / 规则== Complete the diagram with magnetic and shaded non-magnetic tiles. Each magnetic tile has two poles, + and -, with one on each half. Two halves with the same poles cannot touch horizontally or vertically. The numbers at the right and bottom of the diagram indicate how many positive and negative poles appear in that row or column. 完成表格, 畫出格子中的磁鐵正負極或塗黑。每個磁鐵都有兩極 +, -在它的兩端。若是兩塊磁鐵同極性的不能相觸(譯注: 即+ + 或 - - 不得直向或橫向相鄰), 在表格外的數字代表了表格中該直行或該橫列有多少個正極或負極。 ==Solving techniques / 解题技巧== *假設10x10的大小, 所以若是磁鐵+ - 合計起來是9(如+4-5), 那麼當中兩端都在該行或列的一定是有磁鐵的, 可以先把它圈起來。 *另外, 可以由相鄰的行或列, 但差距過大的數字去下手, 例如(+4 -5)和(+1 -1), 它代表了(+1 -1)沒有延伸到(+4 -5)那行列的磁鐵區塊, 多半是要塗黑, 是沒有磁鐵的。 *另外, 若是某一磁鐵端和它相鄰的上下左右同時出現了+及-, 那麼它的本身一定就要塗黑。這一題要不斷在行及列之間交叉確認。 [[File:Magnets-01-sol.jpg|200px|thumb|right|'''Magnets''' example solution, From: 23rd WPC Instrucion Booklet © 2014, UK Puzzle Association]] ==History / 历史== *曾出現於第23屆WPC Round 3 第17-18題 ==See also / 相关词条== *To be edited ==References / 参考资料== *[http://www.uk2014.org/] 23rd WPC 官網 ==External links / 拓展阅读== *To be edited [[Category:Puzzlelist]] [[Category:Place_Objects]] [[Category:Classic_Puzzle]]"
