Crack today's hidden rule from solved examples. One compact daily logic puzzle, with hints, reveals, practice, streaks, and spoiler-free sharing.
Rule Machine is a daily logic puzzle about figuring out how a hidden machine works.
Each puzzle shows solved examples. Study the inputs, infer the rule, then run the final row by entering one missing number. You get three guesses, a hint when you need a nudge, and a reveal that explains the rule after you solve, miss, or choose to peek.
Play today's Rule Machine, keep a local streak, try practice puzzles, revisit completed daily puzzles in the archive, and share your result without spoiling the answer.
What you can expect:
- One compact daily hidden-rule puzzle
- Solved examples and one final missing output
- Hints that nudge without giving everything away
- Rule reveals that show how the machine worked
- Practice puzzles for extra deduction
- Streaks, stats, archive history, and spoiler-free sharing
- Optional Apple account and leaderboard visibility controls
Rule Machine is built for people who like pattern recognition, deduction, and that small "now I see it" moment.
