How CubersDen works

Signed in, every solve is saved to your account, whichever device you time on: the website, or the iPhone, Apple Watch or Android app. They all end up in one history. Without an account, solves stay on the device you timed them on (on the website, only until you close the tab).

What is a session? A session is one sitting at the timer, with one puzzle. The website starts a new one when you open the timer or switch puzzles. You can also start one with New session, or go back to the previous one with Resume last session. The ao5 and ao12 on the timer come from the current session; your personal bests count every session.

What is Latest solves on the home page? Everyone's public solves, newest first, refreshed every minute. Only solves from public profiles show there, and times too fast to be real (a double tap on the timer) are left out. Click a time to open that solve's page.

Where is the scramble? Every solve keeps its scramble. The solve's page draws it on a cube, and Try this scramble lets you time yourself on the same one.

Every solve has its own page, cubersden.com/s/… Clicking a time on the home page, in your history or in competition results opens it. Anyone with the link can open it. With a public profile it shows your name linked to your profile, and search engines may list it. With a private profile it shows your name only, and search engines are asked to skip it.

Every solve page shows the time, the scramble on a cube and where the solve was timed. A solve timed on a smart cube also has a replay of every turn, turns per second, and the phases (cross, F2L, OLL, PLL) with recognition and execution time, including which OLL and PLL case you got. Without a smart cube there is no record of the turns, so those parts are missing.

CubersDen connects over Bluetooth to the MoYu WeiLong V10 AI and to GAN smart cubes (Gen2, Gen3 and Gen4): in the iPhone and Android apps, and on the website in a browser with Bluetooth, such as Chrome or Edge. The website also connects to the GAN smart timer.

With a cube connected, the timer checks your scramble as you turn, starts inspection once the cube matches, starts the clock on your first turn and stops it when the cube is solved. It records every turn with its timing, the cube's model and your inspection time.

The turn record is part of the solve, so it is exactly as public as the solve: anyone who opens the solve page can watch the replay. The same record is what makes the phases, the OLL and PLL cases and a ghost's 3D replay possible.

A ghost is a real solve another cuber recorded earlier: not a bot, and not an invented time. When nobody is free for a live battle, the battles lobby offers a ghost after a few seconds (or straight away with Race a ghost): a public solve of the same puzzle, close to your level. You get the same scramble, and the ghost's clock starts when yours does.

If the ghost was timed on a smart cube, its cube replays their turns in 3D next to your timer, at the pace they made them. Otherwise the ghost is a running clock.

In 1v1 battles you race a live opponent over three rounds, and both of you get the same scrambles, dealt by the server when the match starts. Find an opponent in the queue, or invite a friend with a code. Leaving mid-battle counts the rounds left as DNF.

Every live battle, a friend's invite included, changes your Elo rating. Everyone starts at 1200, and beating someone rated higher earns more than beating someone rated lower. For your first 10 battles the rating is provisional. Your rating and record show on your profile, and the best players are on the leaderboard.

A new week opens on the competition page every Monday at 00:00 Warsaw time and runs until the next Monday at 00:00. Each event (3x3, 2x2, 4x4, 3x3 one-handed and Pyraminx) has five scrambles, the same for everyone, shown one at a time. Your result is the average of five, counted as at a WCA competition.

Times from the timer or a smart cube are verified and ranked together; typed times are ranked separately. To take part you need an account, to be 13 or over, and to accept the community guidelines once.

Results come out on Monday just after 00:10: the podium, and how you did against cubers at your level, on the results page; a notification in your inbox; and your entry in the Results tab of your profile. On the website, competition times stay with your entry and are not added to your timer history.

Badges mark milestones: the first solve, sub-X times, OLL, PLL and CMLL learned in the trainer, solve counts, battle wins, ghosts beaten and the weekly competition. The server awards them on its own, usually a moment after the solve or race that earned them, and a badge stays yours.

Your profile has a shelf of six: the newest you have earned first, then the ones you are closest to, with how far you still have to go.

There are two pages. The first, your profile, is for you only: your name, whether the profile is public, the ghost opt-out, your bio, country, main method, event and cube, your statistics per puzzle and your whole solve history, where you can add +2 or DNF or delete a solve. The second, your public profile at cubersden.com/u/your-name, is what everyone else sees.

With a private profile, others see only your name and a note that the profile is private. Accounts under 16 start private.

Solves are public: every solve you save can be opened at its solve page with your display name, even with a private profile (then without a link to your profile, and hidden from search engines). A private profile shows others only your name instead of your profile page, and keeps your solves off the home page list and out of ghost races.

Everything else, including what we collect and how to delete your account, is in the privacy policy. Questions go to support.
