QED Night
Puzzle co-op · 2 to 8 players

Solve puzzles together, live

Solve puzzles together online: riddles, math, logic grids with exactly one answer. Each player answers privately; the group locks on a majority. Two to eight players, no account.


How it plays

  • The host picks how many puzzles, how hard, and how long each one gets.
  • Everyone reads the same puzzle and answers privately. When half the room agrees, the answer locks and is checked.
  • Three shared hints per run. A wrong lock costs a hint and one more try. Solve six in ten and the whole group wins.
