The exponentiation puzzle supposedly became the extra puzzle; I have no access to it since I'm a non-subscriber. I therefore no longer saw a *need* for my tables, and so I got rid of them. Would it be ok with you if I reposted your table Yes, you have my permission to do so. Thanks |

I agree. The puzzle was more challenging than usual. |

The key to solving this puzzle is to find cross pairs, if you work on looking for cross pairs the puzzle can be solved reasonably easily. I don't know if cross pairs is the correct name to use, as an example of what I mean by a 'cross pair' in this puzzle cage a1(8:)=1&8 and cage h1(10|)=2&8, so rows 1 and 2 have 8 as a cross pair and no other cell can have a value of 8 in rows 1 and 2. Sometimes cross pairs are obvious, but other times they can hide. It is worth the extra effort to find the cross pairs, they can make a big difference. So my steps for solving this puzzle (without going into much detail) are: Look at column c, (a lot can be done in this column). Consider cage d4(3-), with reference to adjacent cells. Then just do all the basics while remembering to look for cross pairs. |

[…] You probably mean an X-wing strategy – well known in the sudoku world. And I agree, this strategy is very useful in this puzzle, especially “double” X-wing in the top two rows: BC12 (#7) + EF12 (#6) eliminate G1 to candidates 4 and 5; 4 causes no position for 6 in the row 1, therefore G1 = 5, thus 8 in the column F must be placed in the row 7. The rest is already easier… |
