How to play

A code is a way of writing where each sign stands for something — a letter, or a number. If you have the key, you can read it. That is all a code is!

The decoder table

  1. Pick a code at the top: Braille, Morse, or Maya numbers.
  2. A message shows up as a row of signs. Under each sign is an empty slot.
  3. Look at the key. Find the sign you are on, and tap its letter or number to fill the slot.
  4. When every slot is full, tap Read it →. If it reads right, the message tells you what it says — and where the code comes from.
  5. Tapped the wrong one? Just tap the slot to clear it and try again. There is no way to lose.

The three real codes

  • Braille — six dots you can read with your fingers. A blind fifteen-year-old named Louis Braille invented it in 1824.
  • Morse code — short beeps (·) and long beeps (—) that once carried messages down a wire, faster than a train. Ships still flash · · · ——— · · · for help.
  • Maya numbers — a dot is 1, a bar is 5, and a shell is 0. The Maya were one of the first peoples ever to write a symbol for nothing.

What it's good for (and what we don't claim)

GlyphPals builds code-and-key reasoning — using a key to turn signs into meaning (the same idea behind secret codes, phonics, and computers). It is not a brain-training program and we make no claim it raises IQ or test scores. Every code here is a real one, with a real story.
