Frequently Asked Questions
Answers to the questions that tend to come up while playing the 3D maze game.
The 3D view won't display.
The 3D view needs WebGL. Update your browser to the latest version and make sure hardware acceleration is turned on in its settings. If it still won't work, you can print that maze and solve it on paper — a print button is shown right on the notice screen.
My records disappeared.
Local rankings live only in your browser's localStorage. If you clear the site data, or switch to a different device or browser, those local records go with it. Records submitted to the global ranking stay safe on the server.
Is the same code really the exact same maze?
Yes. A maze is rebuilt deterministically from the seed inside its code, so it's identical down to the last wall on any device, in any language, at any time. That's what makes fair time competitions possible with just a code.
What happens if I mistype a maze code?
The last character of every code is a checksum, so any single-character typo or swap of two adjacent characters is caught. Invalid codes are flagged before you start — a wrong maze will never open by accident. Easily confused characters like O and 0, or I, L and 1, are corrected automatically.
I removed the fog — can I turn it back on?
No, removing the fog can't be undone for that run. Whether you kept the fog is stored with your record and shown separately in the rankings, so this rule prevents toggling it for an unfair edge. Start a new run and the fog is back.
What becomes public when I join the global ranking?
The nickname you enter and your record (time, difficulty, and mode) appear on the public leaderboard. We recommend against nicknames that identify you personally, like a real name. To delete a submitted record, use the contact address in the privacy policy.
When does the weekly challenge change?
Every Monday at 00:00 UTC, new mazes open in all five difficulty bands. Past leaderboards are preserved, so you can look back at them anytime.
Can I switch between character view and overhead view mid-game?
Not during a game. Copy the maze code, head back home, and start again with the same code in the other mode — same maze, fresh perspective.
My printed maze looks smudged.
At difficulty 17 and above, walls for more than a hundred cells squeeze onto one A4 sheet, so the lines get very fine. On a typical home printer, a slightly lower difficulty prints crisp and clear. A black-and-white printer works perfectly well.
Do I need to install anything or sign up? Does it cost money?
No. It runs right in your browser, needs no account, and is free. Korean, English, Japanese, and Chinese are supported.
