How it works:
- A sequence of letters appears with a pattern (e.g., A → C → E → G → ?)
- Identify the rule connecting the letters
- Select the next letter that continues the pattern
- Get instant feedback and move to the next sequence
Pattern types by difficulty:
- Easy: Simple skips (+1, +2, +3) - like A, B, C or A, C, E
- Medium: Larger skips, backward sequences, alternating patterns
- Hard: Variable skips (+1, +2, +1, +2), double letters, complex alternating rules
Session types:
- Time-based: Solve as many patterns as possible in 60 seconds
- Trial-based: Complete 20 patterns as accurately as possible
Tips:
- Count the "distance" between consecutive letters (A→C is +2)
- Check if the pattern goes forward or backward in the alphabet
- Look for repeating skip patterns (e.g., +2, +3, +2, +3)
- Some patterns alternate between two separate sequences
