INFERNOGUESSR CYBERGRIND HAS BEEN DEPLOYED

A endless gauntlet variant of Infernoguessr is now live. Identify screenshots from random levels before your HP runs out.

  • +20 HP for correct guesses.
  • Missing the target results in HP loss that scales exponentially based on how far off your guess is.
  • Your health constantly depletes over time. This decay rate accelerates as you reach higher waves.

Similar to classic cybergrind, there is a global Leaderboard which ranks you based off of Waves Cleared, using average accuracy as a tiebreaker. Go play and get your rank!

CYBERGRIND UPDATE: NEW MODIFIER

A new modifier has been added to the Cybergrind rotation: IDOL.

When active, some enemies from your recent rounds will be marked as blessed. Guessing a blessed enemy shows no hints.

IDOL joins the modifier pool starting at wave 6 and can be amplified by RADIANCE, which increases the number of blessed enemies and the range of rounds they're pulled from.

Additionally, the maximum modifier count has been raised from 5 to 6 for waves beyond 35, and radiance scaling has been adjusted across all waves.

Since this fundamentally changes how difficulty scales in the cybergrind, leaderboards will only show runs performed on the latest version from now on. I Will add a way to view the "legacy top 10" in a small future update.

CELESTE RECOVERY UPDATE (FINAL)

TLDR: She's no longer in real danger. Not yet healthy but recovery process should continue to go smoothly

First, a quick summary of how things went with the blood work and latest vet visit:

  • Vet came to my house on Monday morning, checked on Celeste and gave us some vitamins we could give her to aid on recovery.
  • For the fleas, vet said we should switch frequency of bathing with the anti-flea shampoo to every 8 days to match the fleas' usual cycle of life. This is only to keep them in line and we will explore stronger methods (like injections) to get rid of them when Celeste gains some weight, and when we do so, we should also contact an exterminator to make 100% sure they are not in the environment either.
  • Vet also noticed that Celeste seems to be feeling some pain in her joints (she won't squat all the way down when peeing) but this seemed to be a separate issue. Vet suggested to try out a mixed BARF diet to avoid possible deficiencies and we will be following that advice.
  • Blood work was done on the same day, we found evidence of blood parasites. We bought a pill the vet suggested and gave it to Celeste. This was a very quick-acting thing; vet said we could expect Celeste to recover her usual appetite within a day, and she did!

She's still yet to gain her usual weight back but the color of her gums and tongue is slowly coming back to the usual pink shade. She's been eating a lot of high-iron food and while she still has a couple fleas here and there, the infestation is not nearly as bad as it was last week!

We expect to see her fully recover with time. At least now we have treated the root cause and things should continue to improve smoothly. We'll also keep an eye out for the possible joint pain the vet noticed.

To wrap things up, I wanna thank everyone who supported me through this. I am extremely grateful <3.

Donations went to:

  • Vet visits
  • Blood work
  • Treatment (Cypermethrin shampoo and powder, vitamin injections, anti-parasite pill)

And they will continue to go towards:

  • Celeste's diet while recovering
  • Future anti-flea treatment
  • Exterminator services

This will be the final update on the situation. Thank you all, I hope you keep enjoying ULTRAKIDLE :)

⚠ PUBLIC NOTICE

Some of you may be aware that a cryptocurrency token was recently created on pump.fun by community members themed around my dog. I did receive support through it towards her treatment, and I'm genuinely grateful to everyone who contributed. It means more than you know.

That said, I want to be transparent: I did not create this token, and I do not endorse it. I have no involvement with it and no plans to be. Please do not buy or invest in it expecting any association with me or ULTRAKIDLE.

ULTRAKIDLE will never have any cryptocurrency or token associated with it. If you want to support the project, Ko-fi remains the only official way to do so.

Colorblind mode has been relocated here from its previous location. Additionally, you can now configure custom color schemes for the hint tiles to your liking.

The guessboard columns can now be reordered to match your preferred layout.

All gamemodes now have small small tweakable behavior options. Check them out and adjust things to how you like to play.

CYBERGRIND HAS BEEN DEPLOYED

A new endless gamemode has been added to ULTRAKIDLE. Identify enemies wave after wave, each correct guess advances you to the next round. Fail to identify the target in 6 guesses and your run is over.

As you progress, random modifiers are introduced to mess with your hints. Hover over (or tap) them in-game to see what each one does. Later waves can stack up to 5 modifiers at once, with RADIANCE amplifying others for extra difficulty.

Your best run is tracked by waves cleared, total guesses, and guess accuracy. See how far you can get.

BALANCE CHANGE: EARTHMOVER DEFENSE SYSTEM

The Earthmover's defense system enemies that shared identical stats have been grouped into pairs. This means they now appear as a single entry rather than separate duplicates.

SYSTEM UPDATE LOG // [18-MAR-2026]

INFERNOGUESSR HAS BEEN DEPLOYED

A new gamemode has been added to ULTRAKIDLE. You are shown a screenshot from an ULTRAKILL level. You guess the level. You are scored based on how close you get. There will be 5 rounds daily with a maximum of 500 points to get.

When the daily challenge refreshed, there might have been some jank on the site or the discord activity, that was me messing things up while trying to finish this new feature before going to bed. Everything should be back to normal now, sorry for the inconveniences.

Big shoutouts to everyone who submitted screenshots in the discord! You guys made this possible. Your tag is shown in-game whenever one of your images comes up.

BALANCE CHANGE: DEBUT LEVEL HINTS

TLDR: Read the how to play section (again)

The yellow hint for the registered at column has been reworked. Previously, it indicated that the target enemy appeared in the guessed enemy's debut level, meaning that seeing someone else's grid with yellow on their last column immediately spoiled that the daily enemy had more than one appearance.

Now, yellow means the correct debut level is within 10 levels of your guess (based on level ordering). This should make the hint still useful while not spoiling anything about the enemy for other players

NEW: SUPPORTER'S BOARD

To show some love back to those who keep the servers running, there's now a Supporter's Board on the home page. If you donate through Ko-fi, your name and donation amount will be showcased on the board for 7 days after your contribution.

It's a small gesture, but I wanted donors to get some visibility for supporting my work on ULTRAKIDLE :)

⚠ CAPACITY EXCEEDED — INTERMITTENT DOWNTIME

Hakita tweeted about ULTRAKIDLE and, well... the servers were't exactly ready what came next. We've been experiencing intermittent downtime and degraded performance due to the massive influx of new players.

I'm actively working on scaling things up to handle the load. In the meantime, if the site is slow or unresponsive, please be patient and try again in a few minutes — your progress is safe.

On a brighter note: welcome to all the new players. Glad to have you here :).

NEW CHALLENGE APPROACHING: INFERNOGUESSR
(accepting submissions!)

Wanna help development while ALSO getting credited in this website?

Hey all, I've been busy with IRL stuff but I've had this idea in mind to implement different gamemodes; one of these being InfernoGuessr (GeoGuessr for ULTRAKILL). Basically you'd have to guess a given level from a single screenshot taken in that level. Specifics of how exactly this will work are still TBD.

For this to be possible, I'd need quite the amount of screenshots, an amount I cannot gather alone. That's why I have opened community submissions!

Want to participate in sending images and/or voting which images get in? Join the official ULTRAKIDLE discord server and check the #infernoguessr-submissions forum!

When the gamemode goes live, whenever your image appears in the game, it will be credited to your discord tag/nickname at time of submission approval.

NETWORK INVITE

Hello machines, may I interest you in joining the official ULTRAKIDLE discord server?

You can do it right here but I also changed the DISCORD link in the footer of the site, previously it pointed to my personal discord profile, now it goes to the invite link for the official server.

That's all, have fun!
