What's New in MindDuel

1.3.5

September 10, 2026

The score is right the first time The number you saw at the end of a round was worked out differently from the one the leaderboard stored: the app used the round's average answer time, while the server scores each answer on its own. If you spent a while on one question and answered the rest quickly, the figure on screen could come out lower than what you had actually earned — and then correct itself a moment later, once the server's number arrived. The app now scores the way the server does. The number you see is the number that counts. Nothing was lost along the way; the leaderboard has had the right total all along. Every game mode is visible when you create a multiplayer game The modes sat in a row you had to drag sideways, so most people never saw there was more than the first three. They are now equally sized tiles, all of them, with nothing to drag. Start level can be picked for Pi as well — there it decides which decimal the game begins at.
