Note that there is no registration for downloads from any app store.
You can download and play Solitaire Forever
Four of the games are free, and you can play them without limits.
(Klondike, Yukon, The Towers, and Eliminator)
You can play any of the other games to try
but they will time-out after 2 minutes.
This way you can evaluate the program before deciding to register.
If you purchase a registration number and
enter it into the program,
the time limit will be removed from all of the games.
You will also be helping to support
and the people whose hard work creates shareware.
Registration costs $25 US.
