88 handpicked Scratch games of Undertale


The appeal of Undertale lies in its unique characters, music, and story that presents the player with important choices that impact the outcome of the game. Players can experience different endings based on their choices, encouraging them to play the game multiple times to discover new outcomes. To express this appeal in Scratch, it is necessary to first create original characters and backgrounds that convey a unique world. Scratch allows for the creation of custom sprites, which can be used to create original characters and backgrounds. Additionally, programming the player with choices that impact the storyline can emulate Undertale's emphasis on choice. Undertale's music is also a crucial aspect of its appeal. Scratch allows for the creation of simple music, which can be used to create original tracks to incorporate into the game. Let's explore how to express these qualities in Scratch together!

#13 Exciting Undertale Adventure

Hey everyone, do you know the game called Exciting Undertale Adventure? You move the character with the arrow keys, and if you bump into the white frame, you’ll be sent back to the center. Watch out! If your health drops to zero, it’s game over! Also, if you stay still for 2 seconds, you’ll take damage, so it might be better to act quickly. By the way, the game over music seems to be credited to Mr. Toby Fox. And there are many others involved too. For instance, there’s @chibisuirakikito and @osakanatengoku who helped with Undertale’s Muffet and the game over screen, @WASABI0123 who provided commands, and @kinngusann who crafted the slash. The inspiration came from @ritumario’s Undertale Character Battles. So, if you’re interested, definitely give it a try!

#17 The Notorious Tabuu from Smash Bros

Invades Ante: An Oddly Perfect Match Between the Subspace Ruler and Ante.

Tabuu, the most formidable enemy in the history of Smash Bros., has arrived in Ante! The compatibility between the ruler of Subspace and Ante is strangely good… Tabuu’s signature attacks are incredibly dense, making the game ridiculously difficult! I can’t clear it at all^^; I can’t help but wonder how on earth to dodge those wave-like attacks that resemble rings of light! They’re so powerful that even a Kanto person might involuntarily let out a Kansai-style retort. Seriously, is there anyone who can clear this?

They’ve also prepared phase 2, and I hear you can enjoy another route if you clear one, so good luck clearing that one!

Shocker breaker ehg (lol)


Alphys is a big fan of Undyne. She's a scientist who researches various things like souls and determination. She has a dinosaur-like appearance at first glance. The battle with Alphys is considered to be the most challenging even in Ink Sans battles, so you can imagine the difficulty level...

He shoots the gas bra in a small, nimble manner. Enjoy the power of the GASBRA, which even Sans-senpai is a tad bit intimidated by.

If you look at the keyboard, you will see that there is a 1 above the Q and a 2 above the W. The speed control corresponding to the Q is 1, so you have a set of upper and lower keys. I think it is a well thought out design.

#03 Undyne Battle Experience with Monster Kid Conversation

souchan3221’s Scratch Gameという口コミを寄せてくれた方 souchan3221’s Scratch Game

The game starts with a conversation between the player and a monster child before the Undyne battle. There is a convenient feature to skip this conversation if desired. There are two modes available: the regular mode where you play the Undyne battle as usual, and a mode where you can only view the conversation with Undyne without losing any HP when attacked. This is perfect for those who just want to revisit the Undyne battle. The game is available in both English and Japanese, allowing non-Japanese speakers to enjoy it as well.

Hey everyone, let’s enjoy battling Undyne! Move with the arrow keys and press Z to progress Undyne’s dialogue. Once the blue and yellow arrows are done, that’s it! This game is even more fun with the addition of yellow arrows to the usual blue ones. The creator keeps updating it, so check it out sometimes. The view count is really impressive too! The creator is open to feedback and welcomes remixes and sharing. Let’s all have fun experiencing the fight with Undyne!

This is a simple template for creating an undertail-ish battle. If you look inside, you will see “Don’t change this” comments scattered, so best that those parts are not changed.
There is a sprite called “enemy” where the original enemies can be created. The Mettaton battle introduced earlier was also created using this template so the possibilities have been proven! Let’s remix thoroughly.

#05 Adorable Moving Skeletons and Learning English Through Gaming

The private note ( saved only in this browser )
potatoempire’s Scratch Gameという口コミを寄せてくれた方 potatoempire’s Scratch Game

I found the moving skeletons in the game to be very adorable. As you progress in the game, there are several word choices available to you. The content involves selecting one of these options, either Papyrus or Sans, and then simply clicking. As you accumulate clicks, you can purchase a number that increases per second in the store. By repeating the process of clicking and purchasing, you will quickly see a large number of counts automatically increasing. The game is written in English, which might be confusing for those who cannot read English, but the words can be easily looked up, and I believe you can also learn English while playing the game.


Yeah, all the characters in Undertale are unique in their own way, but Sans is definitely a fan favorite, right? And this character called "Ink Sans" from Inktale has become so popular that it has created a whole genre of its own! There are a lot of Scratchers who are creating projects specifically focused on Ink Sans, so I'll introduce some of them to you!

You can start invincible by holding down the space key and clicking on the green flag. If you really want to attack, you have to figure out all the attacks once first. Well, if you like Undertale, it’s not hard. Mm-hm.

#08 Character fighting game - low-key challenging

The private note ( saved only in this browser )
kinngusann’s Scratch Gameという口コミを寄せてくれた方 kinngusann’s Scratch Game

A battle breaks out very suddenly on a screen reminiscent of NES. The “escape” command cannot be chosen from the beginning, so there’s no other option than to fight. Next turn, we get attacked, and now it’s a real shooter game. Huh? Was’t this supposed to be an RPG? You’ll lose if you stop and start wondering. As I was being attacked, it reminded me of a shooter game called Gradius. What kind of RPG is this being more difficult as the original shooter game?!

Many people say they enjoy the Sans battle in Undertale, and here’s a project where you can enjoy the Sans battle at the end of Route G by simply pressing the green flag. I tried to clear it as I was curious about the mysterious message from the author, “Press stop after clear and wait for 60 seconds”, but I failed after about 45 turns. Someone, please clear it. Pressing the P key activates the trick, so you have to stop once.

It’s the English version again, but they’ve added a few more attack patterns and it’s getting really tough. I had too many game overs, so the thumbnail is also the GAME OVER one.

The author says it is possible to conquer the game, so please give it a try.

English language skills are not required. Rather, you need the power of your fingers, your eyes, and your ketui.
