The Freecell games, as we found them in the entertainment section on the old Microsoft Windows computers, all use software that generates game numbers. The game you can play on our website uses the exact same system. This software depends on an algorithm that can create up to 10 million game numbers, which are almost all solvable. Because of this, if you wanted to solve a Freecell puzzle every day, you'd need 27,397 years to finish all of them. The advantage of these game numbers is that you can quickly find your favorite game by remembering or writing them down. To input the numbers, simply press the menu icon (three lines) or the game number in the top bar.
