Quiz: 10 questions, pick the letter
Hear or see a character, pick one of four answers or type it. The timer is optional. A wrong answer shows the right character straight away. Good for a first score, or for checking a new batch of letters.

Morse Code Test: Quiz, Decode Game and Speed Test
A Morse code test plays one character at a time and asks you to name it, so it trains what you recognize by ear; listen before looking at the on-screen glyph for a true listening challenge. Pick the quiz for a plain 10-question score, the decode game for a timed round with streaks, or the speed test to find your receiving rate in words per minute. Every miss is listed at the end as a letter to practice.

What do you recognize?
One signal. Four choices.
Pick your mode and press Start. Each question plays the sound, shows the dots and dashes, and gives you four letters to choose from, or you can type the answer.
Quiz and game time count only while a question is open. Speed test runs for 60 seconds.

Three ways to test
Most Morse code quiz pages run one format: decode a character, type it, repeat. This page splits that into a quiz, a Morse code game with streaks and a speed test, because a learner, a returning operator and someone chasing a personal record are not asking the same question. All three draw characters at random from the set you choose and play each one at the speed you choose.
Decode game: timed, streaks count
10 questions with the timer always on. Correct answers in a row build a streak, and your best streak appears on the result screen. The clock only runs while a question is open, so it suits short daily rounds.
Speed test: answer for 60 seconds
Answer as many characters as you can in one minute. The test stops by itself and reports your rate in WPM plus the number of correct characters, so you can measure receiving speed week to week.
How the test works
- Choose a mode, a character set (A–Z, with numbers, or the first 10 Koch letters) and a playback speed of 10, 15 or 20 WPM, then press Start.
- The character plays automatically as a 600 Hz tone while the lamp strip flashes and the dot-dash glyph appears. Press Play to hear it again, or Stop to cut it short.
- Answer by tapping one of the four letter buttons or typing the letter in the box. Typing a valid character submits it at once.
- Feedback appears under the answers: the correct character with its dits and dahs spoken out, and, if you missed, the one you picked.
- Press Next question. After the tenth, See my score opens the results; in speed mode the results open on their own when the minute ends.
If the page says sound is blocked, tap Play once to allow audio. Your answers stay on this device and nothing is sent anywhere.
Letters, numbers and speed settings
The two settings that change how hard a round feels are the character set and the playback speed. Other quizzes vary widely in speed and difficulty settings; this page keeps three sets and three speeds so you can compare one score with the next.
| Setting | Options | When to use it |
|---|---|---|
| Letters | A–Z (default) | The full International Morse alphabet, 26 characters |
| Letters | + 0–9 | Adds the ten numbers once letters are mostly solid |
| Letters | Koch first 10 | K M R S U A P T L O, a Koch-style practice set, for anyone still learning |
| Speed | Slow, 10 WPM | Characters are clearly spaced; good for a first round |
| Speed | Normal, 15 WPM | The speed most quiz tools default to |
| Speed | Fast, 20 WPM | Characters arrive as a rhythm, not as countable dots and dashes |
One caution from operators: practising too slowly trains you to count dots and dashes, and that habit tends to plateau around 10 WPM. If you already pass at 15 WPM, raise the speed or add numbers before adding more rounds at the same setting.
What your score means
A Morse code test score out of 10 only helps if it tells you what to change next. The table below is calibrated to a 10-question round; the speed test reports WPM instead and is explained in the next section.
| Score | What it says | Do this next |
|---|---|---|
| 0–4 | A few sounds are familiar, but most patterns are not yet mapped to letters. | Start with the Koch first 10 set in the practice trainer, then come back. |
| 5–7 | You recognize most of the set, but a few pairs still get mixed up (the result screen names them). | Practice the listed weak letters, then retest at the same speed. |
| 8–10 | This set is solid at this speed. | Raise the speed one step or switch on numbers; an 8 or better at 15 WPM is a useful practice milestone. |
Operators preparing for amateur radio contacts usually aim higher, around 95–100% at 15–20 WPM, because on-air sending does not repeat a character for you.
The 60-second speed test and WPM
The Morse code speed test gives you one minute of random characters and converts your correct answers into words per minute, the same unit used for CW on the air. The page counts a word as five characters, the standard behind the PARIS convention, so 30 correct characters in 60 seconds is 6.0 WPM. The figure is shown to one decimal, together with the playback speed and the number of correct characters.
Two numbers appear on the result screen and they measure different things. Playback WPM is how fast each character was sent; your score WPM is how fast you turned the sound into a typed answer, which includes thinking time and the gap before you pressed Next. Expect the second number to sit well below the first until recognition is automatic.
Other speed tests run a fixed number of rounds as fast as you can. The fixed-minute format here means two attempts are always comparable, so a rise from 4.2 to 6.5 WPM over a week reflects your recognition, not a shorter round.
Why a test beats rereading the chart
Looking at a Morse chart feels like learning, but it only trains you to look up a pattern you can already see. Recognizing a sound you cannot see is a different skill, and research on the testing effect (Roediger and Karpicke, 2006) found that retrieving an answer from memory produces more durable learning than rereading the same material.
That is the reason every question here plays the audio before you answer, even in the quiz. The dot-dash glyph is on screen as a safety net, but if you can answer with your eyes closed the letter is yours. A round takes a few minutes, so spreading several rounds across a week does more for recall than one long sitting.
What to do after the test
The result screen lists every character you missed, plus the one you chose instead, and the Practice these button opens the practice trainer with exactly that set loaded. Drill those until they stop appearing, then return to the test at the same speed.
When recognition is comfortable at 15 WPM across A–Z and numbers, the next skill is sending. The Morse code tapper lets you key characters on the spacebar or screen and checks them, and the learning plan shows where receiving and sending fit in a weekly routine. To look up a single pattern you keep confusing, the alphabet chart has sound for every character, and the decoder turns any string of dots and dashes back into text.

Questions about the Morse code test
Is there a time limit?
The quiz has no time limit; the timer is optional and only there for your own record. The decode game keeps the timer running so you can beat your time, and the speed test ends by itself after 60 seconds.
Are numbers included?
Only when you choose + 0–9; the default set is letters only. Koch first 10 uses K M R S U A P T L O and no numbers.
What speed is the test?
You choose 10, 15 or 20 words per minute before each round, and every character sounds at that speed. Start where the rhythm is recognizable, then move up one step once you score 8 or more.
What is a passing score?
There is no official pass mark for a self-test, but 8 out of 10 at 15 WPM shows the set is solid. Anyone heading for on-air CW contacts should aim for 95–100% at 15–20 WPM before relying on it.
Can I share my score?
Yes. Share score copies one line with your score and speed to the clipboard, ready to paste into a message. Nothing is posted anywhere and no account is involved.
Why does the quiz play audio instead of only showing the code?
Because Morse in use is heard, not read. The glyph stays on screen so you are never stuck, but answering from the sound builds the recognition that a chart cannot.
