Catch the Bubbles
A free game where bubbles rise carrying letters and numbers. The screen asks for one and your child catches the bubbles that have it. Three levels, no clock, and no way to lose.

How do you play?
- Pick a level - Easy, medium or hard. The difference is how many lookalikes appear.
- Read the request - The letter or digit being asked for sits large at the top.
- Touch the right bubble - One tap pops it. A wrong bubble costs nothing.
- Clear the level - Enough correct catches moves you up and a new character is asked for.
About this game
Bubbles rise. Each carries a letter or a digit. One is named, and you touch it.
The levels here are built around lookalikes rather than around speed, which is the decision worth explaining. Speed is the easy lever and the wrong one, because a slow round full of characters a child cannot yet separate is still a reading test. So on easy, no bubble in the round can be confused with the one asked for. That is a rule and not a tendency, checked across 120 rounds per language and coming back at exactly zero. Medium lets lookalikes turn up when the draw produces them. Hard seeds them deliberately, and the round becomes the discrimination exercise itself.
Which characters appear is a decision too. The English pool is twenty-six capitals and nothing else, because A and a should never be the same question for somebody learning to read. In Hebrew the pool is the twenty-two base letters, and the five final forms are deliberately left out: a final form is the same letter in a different position rather than a different letter, and teaching a distinction that does not exist is worse than teaching nothing.
Ten digits sit in the pool alongside the letters. One game, both jobs. Most children recognise numbers before letters, which makes a round asking for 3 a gentler way in than one asking for W.
How much time is there? Easy leaves a bubble up for 4.2 seconds and hard for 2.4. A round ends after four to six correct catches depending on the level, and the levels continue without end.
What does it teach?
Letter recognition
The request repeats and shows large, so the shape sticks without drilling.
Number recognition
Ten digits are mixed into the same pool, so one game covers both.
Telling lookalikes apart
b and d, p and q, M and N. Hard exists for that practice, and easy exists to protect against it.
Hand and eye together
A rising bubble needs a gaze that follows and a hand that arrives ahead of it.
Tips
Read before touching
Most mistakes are a finger arriving ahead of an eye. A fraction of a second of reading removes most of them.
Start with digits
Numbers are familiar to most children before letters, so a round asking for 3 is an easier way in.
Catch them low
A bubble near the bottom stays reachable longest, which matters most on hard.
Stay on easy
If your child still mixes up similar letters, easy guarantees they will not meet any.
What age is it for?
3 to 4
Easy, ideally with digits at first. This is shape matching rather than reading.
5 to 6
Easy alone, then medium. This is when letters start being genuinely familiar.
7 and up
Hard, where the resemblance between characters is the whole challenge.
Parents
Nothing to lose and no clock, so a child who gets stuck simply looks for another moment.
Accessibility
One tap, no dragging and no holding. Bubbles are larger than 2cm square on any screen and rise in fixed columns, so none hides behind another. The character itself carries the information rather than the bubble colour, so colour blindness has no effect. There is no clock and no time pressure, and nothing flashes. The request stays large at the top of the screen for the whole round, so it can be checked again at any moment.
Playing together
Say the letter
Ask your child to name it out loud before touching. You hear whether they recognised it.
Hunt their initial
Wait for the first letter of their name. The game suddenly becomes personal.
You read, they tap
Read the request aloud instead of having them read it. Works well before reading starts.
Count what rose
How many bubbles went past that round? Real counting inside a different game.
Common questions
Is the game free?
Completely. Nothing to pay and no purchases inside the game. Every game on the site is open from the first second.
Do I need to download or sign up?
No to both. It runs in the browser with no download and no account, and we do not ask for an email.
What exactly is the difference between the levels?
How many lookalike characters appear. On easy no bubble in the round resembles the one asked for, verified across 120 rounds per language. Medium lets them arrive at random and hard seeds them on purpose.
What happens when my child taps the wrong bubble?
Nothing. No score drops and no lives run out. The bubble pops and play continues.
Are there ads?
None. No banners and no video between levels.
Does it work offline?
Yes. After one visit the game is stored on the device and runs on a plane.
Are there Hebrew letters too?
Yes, following the site language. Hebrew uses the twenty-two base letters, and the five final forms are left out on purpose because a final form is the same letter in a different position rather than a different letter.
Why only capital letters in English?
Because A and a should not be the same question for a child learning to read. Lowercase is a second shape for the same letter and belongs after the first one is known.
What age is this for?
From about three on easy. Reading is not required, only matching one shape to another, and the request stays visible at the top throughout.
Does it collect data about my child?
No. There is no signup and no name. No session recording and no behavioural advertising. We count how many times a game was opened, with nothing attached that identifies who opened it.
