Field notes
The solo set covers six familiar deduction formats with explicit constraints: four-digit codebreaking in ten guesses, a 1–100 higher-or-lower search in seven, a one-lie clue problem in three, and a nine-coin weighing puzzle with two measurements. The online area advertises rooms for two to six players and nine modes, extending beyond logic puzzles into cards, Othello, and liar's dice. The page notes that online-room time continues even after the browser is closed.
