About Submorse

Submorse is a small, singleplayer app that helps you learn and practice Morse code. Start learning in the tutorial, hone your skills in the practice mode, and compete for a spot on the global leaderboard in the time trials.

The Tutorial

Intended for beginners, the tutorial first introduces you to the codes that are easiest to remember. Once you have completed the tutorial, you will have achieved a degree of mastery. The translations you learn will be in your long-term memory and only strengthened with practice.

Practice Mode

Choose what you want to learn with the Practice Mode. This mode lets you enter a series of characters, words, or sentences you would like to brush up on or learn. These characters can be presented in a random order to sure up your knowledge of translations you struggle to remember. You can also put in words, sentences, or phrases that you already know or are interested in learning.

Time Trials

The time trials let you show off your skills. Offering no help/cheats if you get stuck, they are purely about speed. The shortest times from the trials are displayed on a global leaderboard in the submarine, so go get your name out there!

The Sub

Be sure to explore the submarine for hidden features/interactions. The sub may be small, but it is packed full of detail. ..../.-/...-/.//..-./..-/-. !

✦ AI summary

Players praise this game as an effective and accessible learning tool that teaches morse code and alphabets quickly through a simple, engaging approach, with some appreciating the bonus basketball feature. The main complaint centers on difficulty spikes in later levels, particularly "Alphabet 3," which some find frustratingly challenging despite the earlier smooth learning curve.

Teches the basics of morse well. Some additional sentences and a listening comprehension mode would make this a 10/10.

Look, it's free. There's no reason not to get it, but if you need convincing, look at my playtime. in that time i went from "hmm i think i know SOS" to being able to morse the quick brown fox jumps over the lazy dog in 49 seconds. And thats not a brag, i'm horrible at remembering things. 10/10 - if you want to learn morse code i doubt theres a better and faster way.

Found the game by mistake, took me 60 minutes to master the alphabets completely with the great approach the game uses, learned a skill by mistake while browsing games. 10/10.

Genuinely the best way to learn morse code, although the letters in "Alphabet 3" make me want to rip my teeth out
