Puzzle Timer

Paste a backup to restore

Paste the text you copied with Copy backup. Your current solves are kept — anything missing is merged back in.

Bringing your solves over from csTimer

You can move your whole csTimer history here — every session, with its original dates, scrambles, comments, +2s and DNFs. Nothing is changed on csTimer's side, so your data stays there too.

1. Export from csTimer

1. Open cstimer.net in the browser that has your solves in it.
2. Click the ☰ menu at the top left.
3. Choose Export, then Export to file.
4. A .json file downloads. That is your full history — keep it somewhere safe, it is a good backup regardless.

Do this in the same browser and profile you actually time in. csTimer stores solves per browser, so a different one will export an empty file.

2. Import here

1. Click Import (just left of this ?).
2. Pick the .json file you just downloaded.
3. You'll get a list of every session it found. Check the event beside each one, then click Import.

What to expect

• Your existing solves are kept. Imported sessions are added alongside them, named after the csTimer session with “(csTimer)” on the end.
• Original dates are preserved, so your practice heatmap and progress charts fill in the history properly rather than showing everything as one enormous day.
• Sessions we can't identify default to “Don't import”. csTimer has around 230 scramble types and most are sub-step trainers like PLL, OLL and F2L. A one-second PLL drill filed as a 3×3 solve would wreck your averages, so we ask rather than guess. Set them yourself if you do want them.
• Fewest Moves and Multi-BLD can't be imported — they produce a move count and an “X/Y in T” result, not a time, so there is nowhere here to put them.
• Log in first if you want it on your profile. A large history takes a minute or so to upload after the import finishes.

Importing the same file twice will give you a second copy of those sessions. If you get it wrong, delete the “(csTimer)” sessions and start again.

How to use the timer

• Hold the spacebar until the timer turns green, then release to start.
• Press any key (or tap the timer area) to stop a running solve.
• Quick taps of spacebar are false starts — no solve is recorded.
• On mobile, tap and hold anywhere in the timer area to arm, release to start.
• Tap any time in the solves list to see the scramble it was solved with.
• WCA inspection: press spacebar once to start the 15s countdown; release, then hold spacebar again to arm and release to start the timer. This setting belongs to the session, so a blindfolded session can have it off while your 3×3 session keeps it on.
• Phases (under More) splits a solve into timed stages. Set it to 2 on a blindfolded session and the first press after starting ends memorisation; the next one stops the timer. You get the overall time plus each phase, and averages for every phase. It applies to the session you set it on, and only to solves recorded after that.
• Phase names lets you label them — blindfolded sessions start as Memo and Exec.
• ★ marks your best single in the current session.
• After a solve: press P to toggle +2, D to toggle DNF, or Delete/Backspace to remove the last solve.
• The … button lets you attach a comment to any solve.
• Fullscreen hides everything but the timer (press Esc to exit).
• Your solves live in this browser. Use Copy backup or Export to keep a copy — and if you ever lose them, Restore from server recovers everything recorded while you were logged in.
• Copy stats puts your averages on the clipboard, ready to paste into a thread.
