What helps

• Bug reports: which game and page, your browser, and what you expected. In Gatesmith, the "Copy result" text includes the puzzle number.
• Puzzle corrections: the puzzle number or title and what is wrong. Truth tables are machine-checked, so most issues are in the story text.
• Privacy requests: see the privacy policy for what is stored. Leaderboard entries can be removed on request; mention the game, the day and the nickname.
