Frequently Asked Questions
Answers to the questions that tend to come up while playing the 3D maze game.
On this page
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 with the print button on the notice screen.
My records disappeared.
Finished records are saved automatically in this browser's localStorage. If you clear the site data, or switch to a different device or browser, those records go with it. Records submitted with “Post to global rankings” stay 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 final check character helps detect common typing mistakes, and codes that fail validation are flagged before you start. It does not catch every possible typo, so sharing by link or QR is the easiest way to avoid copying mistakes. O is read as 0, and I or L as 1.
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?
Choosing “Post to global rankings” makes the nickname you enter and your record (time, difficulty, and mode) appear in the public rankings. 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. You'll get the same maze from a new 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.
