Code: Select all
 *-----------*
 |4..|..9|6..|
 |..8|5..|...|
 |...|..3|..8|
 |---+---+---|
 |76.|...|.4.|
 |.35|.2.|..7|
 |.9.|7..|...|
 |---+---+---|
 |.7.|.3.|58.|
 |3..|.6.|2..|
 |..1|...|...|
 *-----------*


The first puzzle, above, has multiple solutions, so it is invalid.



The second puzzle, below, can be solved with nothing more than singles and a few exclusions based on line-box interactions.
Code: Select all
 *-----------*
 |.81|.67|.24|
 |2..|94.|...|
 |...|...|17.|
 |---+---+---|
 |.7.|429|...|
 |6..|1..|...|
 |...|...|71.|
 |---+---+---|
 |5..|...|...|
 |...|..6|..2|
 |.23|...|.8.|
 *-----------*


For example.. there is only one place in box 2 (the center top box) for a 1. Likewise only one place in box 4 for a 1. There is only one place a 2 can go in box 6. The 4 in box 6 must be in row 5, so all other 4s can be excluded from row 5. Etc. Etc.

Thanks for the help, and sorry to say, but i made mistakes in the first puzzle:


It should look like this...

4xx|x96|xxx
xx8|5xx|xxx
xxx|xx3|xx8
---+---+---
76x|xxx|x4x
x35|x2x|xx7
x9x|7xx|xxx

Thanks in advance, yours Nokel

Mac, sorry can't help you there... Your question doesn't have a unique answer (the double dwarf planets Pluto & Charon keep changing their distances from the Sun so the order is not fixed)... I only help people cheat on questions/puzzles/tests/exams with unique answers/solutions... You're on your own against those stupid nerds there...

LOL - and it's even worse. The Ph.D.'s have decided Pluto isn't a planet any more.
