All topics Leaderboard
Every score here was set without the correct answer ever being sent to the player's browser. That is the only reason a public board like this means anything.
No scores here yet this week. The weekly board resets every Monday, so an empty one is an opportunity rather than a problem — play a round and you are top of it.
How these scores are protected
A public leaderboard on a free quiz is usually decoration, because on most sites the correct answers are sitting in the page waiting to be read. Anyone willing to open the developer tools tops the board, and everyone else's score is meaningless by comparison. Three things are done differently here.
The answer key never leaves the server
Your browser is sent a question and a list of options and nothing else. Which one is right is decided server-side, after you commit, and only then is it sent back to you along with the explanation. There is no key in the page source, no key in a network response before you answer, and nothing useful to intercept.
Option positions carry no information
The options are shuffled per game, so "the correct answer tends to be third" is not a strategy here, and comparing two players' pages tells you nothing.
The clock is the server's clock
In Classic mode the server records when it issued each question. An answer arriving after the time limit is a timeout regardless of what the browser claims about how long it took, so pausing a script or editing the countdown on screen achieves nothing at all.
Weekly and all-time exist for different people
An all-time board eventually belongs to whoever played most in the first month. The weekly board resets every Monday, which means someone who found the quiz today can still be top of something by Sunday — and that turns out to matter far more for whether people come back than the all-time board does.
