Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.14/day in the week to Aug 7 → 0.29/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About


The Kaisers Fleet approaches! It falls to you to learn the secret language of Morse Code and repel the naval onslaught through timing, tactics and telegraphy.
MORSE is a wave based strategy game elegantly operated with just two controls, Morse and Artillery:
Enter dots and dashes to navigate an ever changing grid of letters and numbers.
Unleash an arsenal of artillery to reveal hidden enemy positions with the flash of your strike and swiftly sink them with precision and speed.
Between waves, upgrade your reconnaissance and firepower and bolster your blockade of sea mines crucial to holding the line. With each wave the waters change, new letters are learnt, shells are spent, ships scuttled and defences tested. Can you prevail?
Navigate ever changing grid of letters and numbers using the lost language of Morse Code. Learn a handful of simple letters then master the telegraphy tree to fully scale the battlefield. Master different telegraph control schemes such as Iambic and Sideswiper.
German ships are shrouded by the cover of darkness, illuminate their positions using the flash of your artillery strikes. Distant vessels will briefly brighten, land a blast close enough and warships will be permanently revealed.
Rain down salvos of shells on the Kaiser's fleet with your artillery. Deliver direct hits for maximum damage and to save ammunition, consistent precision is rewarded with a faster feed of shells that can breach the hulls of even the strongest ships.
After successfully repelling each assault, pick between a pair of upgrade cards to bolster your arsenal, chosen with either a dot or a dash. Unlock new deadly types of artillery shell, improve your sea mines or enhance your reconnaissance. Upgrades stack so choose wisely!
Deploy a blockade of sea mines to reveal and destroy any ships that slip past your artillery. Mines can be bunched and scattered in various formations. Upgraded mines can withstand damage, have timed detonators and can relay warnings of breaches.
With each wave, a new isogram is chosen, the vertical row extends, the number of units increase and new powerful German vessels emerge from the dark waters. Survive until dawn.


Whilst an enjoyable experience with mouse, keyboard or Steamdeck, the authentic way of playing MORSE is with a telegraph key. Here are some of the different types of "homebrew" hardware that players have fashioned to play the game with. Visit the Steam Discussions for the project to learn about how to build your own, including the newly announced Teaspoon Telegraph.


A frantic campaign mode featuring a midnight breach of the Blockade of Germany.
A skirmish mode to hone your telegraphy skills on a breadth of different words.
40 different characters to learn in Morse Code.
3 different telegraph types and calibration settings to tune to your needs.
Put your knowledge and skill to the test with Expert Mode.
Mix up gameplay with a growing collection of modifiers.
Connect up a homebrew or commercial telegraph key for the authentic MORSE experience.

Slow release dopamine when you play it again a day later and find out you have actually learned morse code. I was just on youtube playing morse code practise audio and writing out the messages in a notebook because this game has got me into it.
[h1]気軽にモールス体験!モールス信号で海戦を制せ![/h1] モールス信号のマニアさんがモールス信号の布教のために作られたゲーム。 作りこみが細かい。(入力形式が3つもある!・リスニングモードなどもある) ジャンルとしてはタワーディフェンスに区分できるだろう。 モールス信号で指揮するのはなんか漢のロマンが詰まっていて、プレイしていてそんなに高度なことやっていないはずなのにモールス信号できてる気分になれるいいゲームでした。 ストーリーはないに等しい&モールス信号さえ打てればあとは勘で何とかなるので日本語化対応しないうちでもプレイには支障ない。 ただ本当にモールス信号初めて!ならメニュー画面で選べる難易度だけではなく、オプション設定でさらに難易度落として少しづつ慣れていかないと厳しいかも。 でも慣れればいいゲームバランスだと思います。 [h3]ゲームプレイについて[/h3] 進軍してくる敵船に対してモールス信号で座標を入力すると砲台の照準が入力した場所にターゲットする。 エンターキーで弾を撃って撃破し、またほかの船をターゲットして...を繰り返して既定の数攻めてくる敵船を撃退する。 自陣に敵船を入れないように全15ウェーブを耐えきろう。 (初心者レベル:Novice・最初に解放されるCAMPAINモード) [h3]このゲーム面白いんだけど...知っておいてほしいこと[/h3] 我々モールスマニアではない一般人も楽しめるような素晴らしいゲーム体験に仕上がっている一方、「これ初心者無理だろ!」「これで初めてモールス信号触った人にクリアさせる気なさそう」という感じでもある。 死んで覚えろ!/やりながら学べ!系のゲームならこんなものかという感想だが、モールス信号を体験してみよう!のゲームだとしたら敷居が少し高いと思う。私は初見おすすめ難易度で半泣きになった。 でも詳細設定でさらに難易度を下げることもできる。優しい。 以下、オプション設定をいじらない初心者向け難易度(Novice)で遊んだ感想を述べる。 ・常時夜間なのが辛い このゲーム、デフォルトは夜設定なのである。 夜なので、敵が見えないのである。 ではどうやって敵を探すのかというと、空撃ちすると着弾した場所の周りの船が一定時間見えるようになるのである。照明弾も一応ある。 索敵のための空撃ち→見つけた敵に座標を合わせるという2工程であるため、純粋にキャパオーバーに陥る。 ある程度文字を覚えて爆速でモールス信号を打ててやっと土俵に立てるような気がしなくもない。 オプション(左下のModifiersのLIGHTSONを有効化)でどこでも船が見えるようになるので、初学者は入れたほうがいいと思う。 ・座標が多すぎる 最初のほうはマップが1×7くらいしかないが、最終的に7×6くらいになる。 マップが広すぎるし、使う文字が多すぎて混乱する。 文字を打ち間違えて別の文字に化けようものなら、意図しない座標に照準がぶっとんで一気に戦線崩壊する。 これに夜で船が見えない仕様が合わさって最終日は凶悪な難易度になっている。 また横座標は日ごとに変わる単語由来のアルファベット、縦座標もアルファベットが充てられてるのもなかなかしんどいものである。 これはModifiersのBUTTLESHIPを有効化すると縦座標が数字になるので混乱を少しは減らせる。 以上のことから、 少なくとも難易度NoviceにしたうえでModifiersのBUTTLESHIP(縦座標数字化)/DROPANCHOR(敵速度低下)/LIGHTSON(常時暗視)を入れて、慣れてきたらModifiersを減らすといい塩梅かと思われます。

Excellent concept, simple mais renfermant une complexité et un côté éducatif qui méritent qu'on s'y arrête. Après quelques minutes à peine, on commence à comprendre le morse. Le jeu offre un bon défi qui garde le joueur alerte.
This is such a fun game, and it teaches you morse code on the sly! Genius. For any parents reading this I'd say this game is suitable for all ages - which is rarely something you can say these days. Love the cosy retro music too, something about this game leaves you feeling satisfied. I know that I should feel frustrated losing out at stage 9 in the campaign but I don't for some reason. I suspect some form of magic. Truly wholesome family fun, and with the way things are going in the world right now it probably doesn't hurt to learn a bit of MORSE code just in case ;)
This game literally taught me to read and write Morse code in a single day. It's a fun and educational challenge that, at a certain point, had me genuinely impressed both with myself and the game for how fast I started to memorize Morse code. About 13 hours of gameplay and I had beat expert mode without even pulling up a cheat sheet on my phone. The music is also incredible, though I wish there were more soundtracks. I read the patch notes for a recent update and I saw that the developers had added user suggestions, so I have couple suggestions of my own I think would be great. First, an endless mode, or at least a much longer game mode that's something like 50 waves as that would make the Scuttled achievement much less monotonous. With an endless mode, you would also need new upgrades so you don't just run out of stuff to unlock so I thought of a couple of those too. Reserve ammo increase: A one time upgrade that let's you hold 4 shots instead of 3. This would of course make sense to require the accuracy quota to unlock it. Mine shot: Initially fires a single mine on target space with subsequent upgrades allowing 2, then 3 mines in one shot. This would need to be a rarer shot to acquire, but it make for a much more defensive shot type. Flare Shell: A cross between the suppression shell and the recon shell that flashes three times. It would not mark ships like the recon shell, or do as much damage as the suppression shell, but the multiple flashes would be much more useful in heavy fog. Final comment. I support the motive of the final message in the credits. Games should be for everyone to enjoy.
super game, nur insanes skill issue auf meiner seite
Simple, yet hard to master. Very well done. I miss, however, a Borderless screen. But overall, a good game. 7/10
The game is cool, it's fun, the only thing I wish was there was a mode that was more for training people on CW, what if you had a mode that showed you the hint for letters one time, you memorized them, and then you had to key it or you lose health? There's very little in the game to reinforce or teach new CW short of just hoping a random letter shows up, maybe you unlock a mode more like that later and I haven't yet, but that would be a fantastic way to gamify learning CW, the mobile game MorseMania does an OK job of gamifying it, i think if you could use a similar approach, but integrate it into your game, you'd have a lot of success!
As someone that recently received ham radio license not thinking at all about telegraphy this game surprisingly instantly pulled me in. From the sounds, music, bits of story we get between rounds and the graphics everything seems to perfectly blend together. With each round and increasing difficulty I just found myself entering state of flow and it all just ... clicked Honestly try out the demo and if you like the concept ? give full game a try and check out your local ham radio clubs ! stuff is interesting !
games awesome. I had no interest in morse code beforehand but i did have an interest in ww1. I wanna buy a telegraph irl so bad now ngl. games so sick. maybe more music but otherwise gameplay and atmosphere is fantastic.
