How it works
The wheel shows a code of dots and dashes, and you choose the letter or number it stands for. A dot is a short signal, a dash a long one.
Your score and your run
Every right answer adds to the Score, and the run counts how many you got right in a row. Best run remembers your record on this device.
Pick the topics
Learn the first half of the alphabet, then the second, and leave the Numbers for last. They follow an easy pattern: count the dots.
Easier or harder
Under Quiz settings choose how many Answers to choose from, and switch on Take the ones I got right off the wheel to work through the whole set until nothing is left.
A tip for learning it
Say the code out loud, with “dit” for a dot and “dah” for a dash. People who know Morse hear rhythms, not dots. E and T, a single dot and a single dash, are the easiest of all, so they are left off this wheel.
