Sedoku 

Honorable suicide commited by Samurai after they have shamed themselves or are failed their masters. Samurai could be ordered to commit suicide by their lords (Daimyo)
The samurai would disembowel himself, and when the pain got to be too much to where he might shame himself, his second would decapitate him.

commit sudoku 

A deliberate misspelling of "seppuku" — the samurai ritual of suicide by disembowelment. The misspelling removes the direct reference to suicide, replacing it with the name of a popular and frustrating number puzzle.

I have brought great shame to my brethren. I must now commit sudoku.

Bob: Hi Sally, I was just wondering if everything was ok? I saw you from accross the cafe and, well to be honest you've been sitting there for
over and hour and you haven't moved a muscle.

Sally: Huh? Bob! oh Bob! Thanks Bob, I must have had a bad case of Para-Sudoku-Psychosis. I get like that sometimes when I get stuck
on a difficult Sudoku.

Sudoku 

It's a popular Japanese math game commonly found in newspapers and publications with related games (crosswords, etc.)

On online message boards, particularly 4chan's /v/, people mix the word for Japanese ritual suicide, "seppuku," with "sudoku." The typo has since spread and became adopted in a similar fashion to "pwn" in regards to "own."

"If you seriously gave EA your money for that piece of sh*t you should just commit sudoku."
