It's so fun to solve riddles! But coming up with one is so difficult!

I have no talent at all for solving anagrams so I am going to sit this one out.

Riddles should be in 'what am I?' form, right? My bad :)

Here's a new one:

A big box with clever arrangement within 
Fits smaller boxes of perfect squares 
Introduced in Japan, now you can see me daily 
I'm fun for those who like numbers! 
What am I?

I'm guessing no, but I'm going with a Rubik's cube. Just to get the ball rolling.

Ahhhhh, this is the type of riddle I am more used to. I will give it a shot though it is only a wild guess ....

Is it Sudoku ?

OH MY ! I am not going to pursue that response with further inquiry ~LOL~ ... but I will vouchsafe that the answer to the riddle is something that you, at one time or another, most certainly DID do yesterday.

HINT: All of the original clues are independent of each other and express a solution to different meanings of the same word, or abbreviation(s) of said word.
