Playing the game

This game is commonly known as Forty Thieves and it uses two decks of cards (104). And the goal is to move all of them to the eight foundation piles above the ten card columns - starting each pile with an ace and ending it with a king.

Here is how you do it:
Notes:
A useful tip is of course to try to build suits in the columns, so you can dump several cards simultaneously and more easily get an empty column.

Right-clicking the Exit button will show the background without any disturbing buttons and cards. Right-clicking the background will restore the window.

Clicking the score panel will turn on a small win/lose video in that panel. Clicking it again will close it.
