# Happy 2017 Sudoku

This is a simple Sudoku. The only thing different from a regular sudoku are the symbols used: HAPY2017*. The snowflakes (a.k.a. asterisk) are like any other character.

Wishing you a Happy New Year 2017 and have fun solving puzzles!

• Your image is missing a symbol in the top row. :) Otherwise, this is the solution. – Maria Deleva Jan 6 '17 at 19:36
• @MariaDeleva oh oops! Thanks for pointing that out, will edit... – Beastly Gerbil Jan 6 '17 at 19:36
• @MariaDeleva edited to correct – Beastly Gerbil Jan 6 '17 at 19:39
• @randal'thor I didn't run a program to solve it, just used excel as paper to write on. Can't tell if you are joking if you are then :P – Beastly Gerbil Jan 6 '17 at 19:48
• @MariaDeleva adding steps now... (Doing them in batches of 6 moves, so 9 steps here total) – Beastly Gerbil Jan 6 '17 at 19:49

I'm not sure how to really explain the solution of a Sudoku, beyond writing out all the deductions square by square (which would take too long), so I'll express the solution in a series of progress reports. First stop:

Fill in all the remaining Ps, As, and 0s (in that order), then the bottom row, a few more bits and pieces, and all the remaining *s, to get:

And after the final round of deductions:

Which is the solution.

• Beastly was quicker. :) But I have upvoted your answer as well. :) – Maria Deleva Jan 6 '17 at 19:42
• @Maria Thanks :-) I hadn't even seen Beastly's answer - was so engrossed in solving this! – Rand al'Thor Jan 6 '17 at 19:47
