32+ WPM pace. Aggressive AI and minimal reaction time.

Online Multiplayer

  2. Both players place ships locally.
  3. Click Ready (Upload Fleet).
  4. When both fleets are uploaded, the battle starts.

Winning Strategy

Fleet Placement

  • Mix edge and center placements.
  • Use both horizontal and vertical orientations.

Morse Performance

  • Prioritize clean copy over speed early.
  • Use Replay less often as accuracy improves.
  • Target 85%+ decode accuracy before moving up.

Troubleshooting

I cannot join multiplayer

You must be logged in. Also verify room code and that the room is still open.

No sound or weak Morse tone

Raise tone volume, check browser audio permissions, and confirm output device.

Move rejected by server

Likely not your turn, duplicate coordinate, or temporary rate limit. Wait and retry.
