Twitter/X Puzzle Blocker by keltan

Twitter Puzzle Blocker helps you be more intentional about your social media usage by requiring you to solve an advanced probability or statistics problem before accessing Twitter/X each day.
How It Works:
When you visit Twitter or X.com, the extension blocks the page and presents you with a challenging puzzle. Solve it correctly, and Twitter is unlocked for the rest of the day. At midnight, the puzzle resets.
Puzzle Types:

Bayesian Probability: Medical test accuracy, false positive rates, and real-world conditional probability
Standard Probability: Dice, cards, drawing without replacement, combinations
Conditional Probability: P(A|B) problems with practical applications
Expected Value: Gambling scenarios, risk/reward analysis, multi-outcome problems
Complex Probability: Binomial distributions, multi-stage events

Features:
✓ Blocks Twitter and X.com until puzzle solved
✓ Advanced probability and statistics problems
✓ Daily reset at midnight
✓ Clean, modern interface
✓ No data collection - works entirely offline
✓ Helps build mindful browsing habits
Perfect for students, professionals, or anyone who wants to think twice (and do some math!) before diving into Twitter. Great for reinforcing statistical thinking skills while managing screen time.
