How to play

Each round, a point is hidden somewhere on the board. Your goal is to find it using sonars.

1. Place sonars — Click anywhere on the board to drop a sonar. You can place up to 5.
2. Read the pulses — Each sonar pulses at a different speed. A fast pulse means it's close to the hidden point; a slow pulse means it's far.
3. Propose your guess — When you're ready, click "Propose my guess", then click on the board where you think the hidden point is.

The game lasts 3 rounds. Try to maximize your total score!
