What Is Worth Writing About
Corrections are the most useful thing you can send. Every geography and football answer was checked against a published source before it shipped, but football and geography both move, and a figure that was right when it was written can stop being right. In the brain and chess games, a puzzle with a second answer that also works is just as worth reporting. If a question looks wrong, saying which game and which question is enough to find it.
Bugs are the other one. The games are played on every size of phone, so a layout that breaks on yours is worth reporting even if it sounds small. It helps to say which game, and roughly which phone or browser.
What This Site Does Not Do
There is no account to recover, no subscription to cancel and no payment to refund, because none of those exist. Nothing on Quizebra costs anything and nothing asks you to sign up. If you want to know what is stored when you play, that is set out on the privacy page.
Otherwise, the games are at geography, football, brain and chess.
