Flag semaphore alphabet

Each letter is a position of the two flags, shown as you would see the signaller. Tap a letter to add it to your message.

How flag semaphore works

  1. The signaller holds a flag in each hand. Each arm points to one of eight positions around the body, like the hands of a clock.

  2. Every letter is one pair of positions. A to G keep one arm down while the other moves around the circle.

  3. Hold each letter for a moment, then move to the next. Between words, bring both flags down in front of you.

Use semaphore in your own escape room

Hang semaphore figures around the room as posters, photos or little paper people, and let players spell out the code. It works brilliantly for pirate, sailor and scout themes. Our printable escape rooms are full of puzzles like this, ready to print and play tonight.

Flag semaphore questions

What is flag semaphore?

Flag semaphore is a way to send messages by holding two flags in different positions. Each position stands for a letter. It has long been used at sea to signal between ships, and scouts still learn it today.

What colours are semaphore flags?

At sea, the flags are usually split diagonally into red and yellow, which is the style used on this page. On land, blue and white flags are often used so they stand out against the background.

How do you signal a space between words?

Between words, the signaller lowers both flags in front of the body in the rest position, then starts the next word.
