Using Deduce

• Deduce is provided free of charge for personal, non-commercial use.
• Play fairly: don't attempt to cheat the leaderboard, automate solving, scrape puzzles, or interfere with the service or other players.

Optional Google sign-in lets you save your streak across devices. You're responsible for your Google account; keep it secure. We may suspend access for abuse or attempts to game the leaderboard.

No warranty

Deduce is offered "as is", without warranties of any kind. We aim for high availability and accurate scoring but don't guarantee the service will be uninterrupted or error-free.
