This page keeps a record of your games on your own device. Nothing here needs an account. Below is a simple way to use it, plus a few tips for getting a clear picture of your progress.
Say you have played 12 games and solved 9 of them. Your solve rate is 9 Γ· 12 = 0.75, or 75%.
Now say those 9 solved games took 36 guesses in total. Your average is 36 Γ· 9 = 4 guesses per solved game.
A week later you have played 20 games and solved 16, using 56 guesses in total. Your solve rate is 16 Γ· 20 = 80%. Your average is 56 Γ· 16 = 3.5 guesses. Both numbers improved, and you can see it because you worked them out from the same two figures each time.
These numbers are only an illustration. Your own page may show different figures, so use the same method with whatever it displays.
You may be using a different browser or device than before, or a private window. Saved data may also have been removed if you cleared your browser data. In that case the history cannot be recovered from this page.
No. Because the stats live in each browser, your phone and your computer keep separate records. Each one only shows the games played on it.
Yes, but it cannot be undone. Clearing removes the saved results from this browser only, and your counts start again from zero. If you want to keep a record first, write down the figures you care about, such as your solve rate or your average guesses.
