There are some impossible games in FreeCell. If you are playing a numbered deal then you will be notified when the cards are dealt that the deal cannot be solved. But, if you are playing a random deal, there is no game number to determine if the game is impossible or not. As a reference tool the following game numbers are not winnable:
- #11982, #146692, #186216, #455889, #495505, #512118, #517776, and #781948.
Below is an image of each of these games when dealt. You can use this to check and see if the random game you started playing is one of these impossible deals.
