Unique Rectangle Type 3<\/p>\n\n\n\n

This technique combines the Unique Rectangle with the “Naked” \\ “Hidden” techniques<\/p>\n\n\n\n

  1. If you look at the example, you can see that two cells in the Unique Rectangle have extra candidates: 4, 6 and 6, 9<\/li>\n<\/ol>\n\n\n\n
    \"Unique<\/figure>\n<\/div>\n\n\n\n
    \n
    \n\n\n\n
      \n
    1. This means that the values 4, 6, and 9 are the candidates for these two cells<\/li>\n<\/ol>\n\n\n\n
      <\/figure>\n<\/div>\n\n\n\n
      \n
      \n\n\n\n
        \n
      1. This forms a Hidden Triplet pattern when combined with the two cells in the same column that also contain the values 4, 6, and 9. Therefore, 4, 6, and 9 cannot be placed in any other cell in the column<\/li>\n<\/ol>\n\n\n\n
