How do you lose in Bejeweled 2?

Bejeweled 2 Deluxe edition is free (only today) due to a 10 year anniversary, and I decided to get it. But i just can't lose it? Do you simply have to go on until there are no more solutions? That is going to take a few hours...|||There are times when based on the moves you make, there will be no more possible moves and you will have to start over. Doesn't happen a lot though.|||you can't|||Huh?|||it is never ending. its fun to play tho
