CW Learning Tools

Turn each shot into a stronger copy exercise when you want more training pressure.

Training Mission

Standard tactical mix balances letters and digits across normal play.

Strict copy mode: only the transmitted coordinate can be fired Show coaching notes and weak-symbol focus

Free-fire is more game-like. Strict copy is better when the goal is first-copy accuracy under pressure.

How to play

1. Deploy

Place your five ships manually or with random placement. Rotation is allowed before battle starts.

2. Decode

Each player turn, a coordinate is sent in Morse. Decode it and enter your shot quickly and accurately.

3. Engage

Hits and misses update both tactical boards. AI behavior scales from random to probability-driven hunting.

4. Win

Sink all enemy ships first. Track your decode accuracy and hit rate by difficulty over time.
