## What is Thread?

Solve today's puzzle and see if your friends are as smart as you. Every puzzle contains clues, red herrings, and a hidden rule.

Thread is a deduction puzzle game where your goal is simple: find the common thread connecting the clues. You're shown values that fit the rule and values that don't. Use your powers of deduction to work out the hidden rule behind each puzzle.

You have unlimited tests, but only three guesses to name the rule, so use them wisely.

How it works:

- IN values follow the hidden rule. OUT values don't.
- Run as many tests as you need to build your theory.
- When you're confident, guess the rule.
- OUT results and incorrect guesses reveal a new example to help you along.
- Spend a guess to unlock a hint if you get stuck.

What's included:

- A brand new daily puzzle every day
- Easy, Medium, and Hard free play levels with 10 puzzles each
- Streak tracking
- Shareable results to challenge your friends
- Get all 60 free play levels and the full daily archive with a one-time purchase

Some rules are obvious in hindsight. Others will make you question everything you know. The more you solve, the better you'll become at thinking beyond the obvious to find the right solution.

Think you can find the common thread?
