Jellimo

Tap the falling jellies. One round is three minutes.
No app, no sign-up — open the link and you are already playing.
It looks cute. On 🔥Nuclear you will not last 10 seconds. 😏

Good for

All you need is someone to laugh with

The rules take three seconds. Someone who has never played can join the same round.

👨‍👩‍👧

With family

Kids on Mild, adults on Nuclear. The same game at each person's own speed. No ads and no payments, so handing it to a child's phone is a non-event.

Living room on a Saturday · one round beside your kid

💗

With your partner

One round to settle it. The winner dances with a trophy, the loser folds their arms and sulks. That face becomes a picture you can bring up for weeks.

In a cafe · on the phone in the evening

🧑‍🤝‍🧑

With friends

Drop a 4-letter room code in the group chat and up to four people are in. Nobody waits for a download, so you go from "let's play" to playing in under a minute.

Group chat · lunch break · after work

Six of the characters — cat, dog, bunny, bear, boy and girl

Nine characters · 12 hairstyles · 8 skin tones · accessories

Why people keep going

Cute is not the same as easy

Three lines of rules, and almost nobody clears a minute on the hardest setting. You start because it is easy. You stay because it is not.

🔥

Nuclear

2 lives · jellies fall 3.2× faster · 15% bombs. You will double-check that it is the same game as Mild.

You will not last 10 seconds 😏

♾️

Endless

No timer. Every 5 levels a giant boss comes down, and if it reaches the floor it takes a life with it.

Sit down for one round, look up 20 minutes later

Survival ranking

Ranked by how long you survived, not by score. "12,400 points" means nothing to anyone. "1 minute 12 seconds" means everything.

A number you can actually brag with

Trailer

See it before you play it

Not a mock-up. A script actually played the game and this is the recording.

Turn the sound on 🔊 — the effects and music are the game's own.
Dress up → solo → giant boss → 🔥Nuclear → live dungeon → throw game → the ending picture

Three ways to play

Good alone. Better with someone.

Tap a falling jelly and it pops. Chain them for a combo. Leave the bombs alone.

Solo play screen

Solo — exactly three minutes

Three minutes in a queue, three minutes before bed. Four difficulties: start on Mild, move up to Nuclear once your hands warm up.

You bring five items in — heart pack for lives, slow-mo to buy time, and bomb sweep · double score · magnet for when it goes wrong.

Live dungeon screen

Live Dungeon — 2 to 4 on one board

The same jellies fall on everyone's screen at the same moment, and you watch the other scores climb while you play. The last ten seconds are always the loudest.

Fill the gauge and throw junk at them — zigzag to make jellies swerve, fog to blind them, speed-up to drop everything faster.

Throw Game screen

Throw Game — split the roles

One person throws, the other defends. The thrower watches your screen and aims for the gaps; the defender has to pop everything. This is the mode that works when two people are nowhere near the same skill level.

Hit swap roles on the rematch and you trade sides. Four things to throw: plain, bomb, ghost and jelly rain.

The part people screenshot

Winner dances. Loser sulks.

A round does not end in a number. It ends in a picture.

Six expressions — neutral, excited, surprised, smug, annoyed, in tears

The same character wears a different face every round

🏆

The ending is a picture

Face, pose and speech bubble change every round. Whoever loses watches the winner's screen, and the whole scene is one tap away from being shared.

🎀

Make your own jelly

Nine characters, 12 hairstyles, 8 skin tones and 12 accessories — plus a workshop where you build your own. Coins come from playing, never from paying.

🤖

Practise against the AI

Nobody around? Four AI skill levels, and it works with no internet. Change the skill or swap roles on the rematch.

Win and loss ending pictures

What you keep from a round

The winner holds a trophy, bounces, or sticks their tongue out. The loser folds their arms, stamps a foot, or bursts into tears. Tap to change the speech bubble like sending a message — it appears on the other screen straight away.

The picture is drawn with the character you made. Save it or drop it in the group chat and that is today's scoreline.

Three lines of rules

If it is your first time

BasicsTap a falling jelly and it pops. Let one reach the floor and you lose a life.
Combos and bombsKeep popping without a break and the multiplier climbs. Never tap the angry face (😡) — knowing what to leave alone is half the skill.
Playing togetherMake a room and you get four characters. They type them in and you start in the same room. Items are the row along the bottom.

You don't actually need to read this. The game teaches you on your first round — tap a jelly, chain a combo, let a bomb go past. Thirty seconds and you're done.

How it was built

The whole game is one HTML file

Drawn straight onto a canvas with no game engine. Live matches run on Supabase Realtime.

One file is the game

Rendering, sound, networking and saving all live inside index.html. No engine and no build step, so it will still open and run in six months.

Live matches

Rooms, scores, attacks and spectating go over broadcast. The board itself is never streamed — only what changed — so it survives a bad connection.

Difficulty was measured, not guessed

The four levels came from measuring what the AI actually scores in two minutes. The easiest setting went from 20,406 to 6,576 points — the goal was a sparring partner a person can beat.

It checks itself

Overflowing layouts, buttons that are too small, 2- and 4-player networking and AI difficulty are all tested automatically. Every screenshot and the trailer on this page were made by a script actually playing the game.

It started as something to play with my kid, and grew a room you can drag your friends into. I wanted a round to leave behind a moment you both laughed at rather than a number — so the winner dances and the loser sulks.

FAQ

Answered in advance

Do I have to install anything?

No — open the address and you are playing. Add it to your home screen and it opens full-screen like an app, and solo play keeps working with no internet.

What age is it for?

If you can read a little, you can play. Nothing violent and nothing frightening, and on Mild the jellies come down slowly. A child and an adult can share one room on different settings.

How do I play with a friend?

Make a room and you get a 4-character code. They type it in and you start in the same room. Two to four players, and it does not matter who is on a phone and who is on a laptop.

Is it free? Are there ads or purchases?

Free, and there are no ads. In-game coins only come from playing — there is nothing to buy at all.

Does it use a lot of data?

Almost none. A match only exchanges short messages — scores and attacks — under 1KB each.

Do I need an account?

No. Solo play and AI matches need nothing. An account just carries the same character and coins between your phone and your laptop.
