When do the daily games reset?
Every daily puzzle changes at midnight Eastern time (ET), and everyone gets the same one that day. Ballot's results unlock at the same moment. JustRace and Slopey post a new course every day too.
Do I need an account?
No. Every game is free to play without one, and today's progress is saved in your browser. A free account adds your results to your stats and streaks, keeps your progress in sync across devices, and lets you add friends to compare scores. Crowd and Ballot count your answers either way.
Can I keep playing after today's puzzle?
Yes. RGB, Glance and Gloop have practice modes. Squeeze, On the Dot, Outline and Stack let you replay past days from their archives. JustRace and Slopey have unlimited practice, and WikiRun and JustRace have Party mode for playing with friends.
How do I report a problem with a puzzle?
Use the contact page. Include the game, the puzzle number or date, and what looked wrong. That's enough to check it against the puzzle data and fix it.

Deduce started as a way to build something from scratch: the kind of daily puzzle site I'd actually want to check every day. Every game gets its own look, sounds and little world, from a 1960s motel to a county fair, because each one should feel like its own small game rather than a reskin of the last. Puzzles and features keep being reviewed as the site grows, and game ideas are always welcome on the contact page. More about Deduce.
