How to Play

1. Select a difficulty mode - Choose from:
   • Letters only (A-Z)
   • Alphanumeric (A-Z, 0-9)
   • Full character set (letters, numbers, punctuation)
   • Words or phrases
2. Configure your game - Set the number of rounds (5-50) and time per round (3-60 seconds)
3. Enable dynamic time (optional) - For words/phrases, time can scale based on character count
4. Translate to morse code - You'll be shown a challenge
5. Enter your answer - Type the morse code using:
   • . (dot) for short signals
   • - (dash) for long signals
   • Space to separate letters
   • / to separate words
6. Get instant feedback - See if you got it right and what your input translates to if wrong
7. Review your performance - After all rounds, view detailed statistics

Morse Code Basics

• Use . for dots and - for dashes
• Separate letters with spaces
• Use / for word boundaries
• Supported punctuation: . , ? ! - / ( ) @
• Example: HELLO = .... . .-.. .-.. ---
• Example: SOS = ... --- ...
• Example: HELLO WORLD = .... . .-.. .-.. --- / .-- --- .-. .-.. -..

Statistics

The game tracks:

• Total games played
• Total rounds completed
• Correct and incorrect answers
• Overall accuracy percentage
• Average time per round
• Best streak (consecutive correct answers)
• Per-mode statistics

Stats are saved to ./data/stats.json in the project directory.

When you answer incorrectly, the game shows what your morse code input actually translates to, helping you understand and learn from your mistakes.
