Play 1 to 50 online.Tap the numbers in order, as fast as you can.
Twenty-five tiles, fifty numbers. Tap 7 and 32 takes its place. It is the whole game, free in this tab — no install, no sign-up — on the app's real rules and the app's real clock.
A Schulte table that runs to 50
The board above is a 5×5 Schulte table — the grid of shuffled numbers you clear in order, used for years as an attention and visual-scanning drill. One to 50 doubles it: clear 1 to 25 and the second pass, 26 to 50, arrives one tile at a time in the gaps you just made.
So the number you want is never where you left off. You cannot count along a row; you have to hold the whole grid in your peripheral vision and jump. That is the difficulty, and it is why the exercise is used for speed reading and focus practice as much as for a score.

Every run you have played
The same graph, for good — every time in the order you played it, personal best marked, so you find out whether you are actually getting faster.
A global board per mode
Take a name, submit a score, and find your own row lit up in the stack. No password and no email — a name nobody else has taken is the whole account.
Time mode runs to 125
Twenty seconds, and the board keeps reloading past 50, past 100. Really fast fingers get past 100. Most fingers do not.
Your colours, your board
Pick the colour for each mode, the background, the tap animation and the size of the numerals. The whole app repaints around what you choose — the way this page just did.
Questions about 1 to 50
The things people ask before they tap the first tile.
Can I play 1 to 50 online without installing anything?
Yes. The board at the top of this page is the complete game, playable in any modern browser on a phone, tablet or computer. There is nothing to download, no account and no payment. Tap 1 to start the clock, then work your way up to 50. The mobile apps are free as well, and they add a saved history and a global leaderboard.
How do you play One to 50?
Tap the numbers 1 to 50 in order, as fast as you can. The 5×5 grid starts out holding 1 to 25 in shuffled positions. Each time you tap the right number, that tile is refilled in place with a number from the 26 to 50 pass, so the board keeps reloading underneath you. A wrong tap does nothing. The clock starts on 1 and stops on 50.
Is One to 50 a Schulte table?
Yes — it is a 5×5 Schulte table extended to fifty numbers. A classic Schulte table is a square grid of shuffled numbers you clear in order while keeping your gaze near the centre, used to train peripheral vision, selective attention and reading speed. One to 50 keeps that grid and adds a second pass on top of it, so the layout changes while you play.
What is a good time for 1 to 50?
The app grades every finished run on its own scale, the one printed further up this page: 40 to 70 seconds is called perfectly average, 25 to 40 seconds is very good, and 10 to 25 seconds is the top band. Faster than ten seconds and the app stops believing you. Your first run will be slower than you expect; the second is usually a lot faster.
Does the browser game work on a phone?
Yes, and it is built for touch first. The grid scales to the width of the screen and registers a tap the moment your finger lands, the way the app does, so there is no lag between the tap and the tile. It runs in Safari on iOS, Chrome on Android and any current mobile browser. For offline play and a permanent record, install the app.
Is One to 50 free?
Yes. The browser version on this page is free and needs no account, and the One to 50 app is a free download on both Google Play and the App Store. It is rated for ages 4 and up, which is roughly the age at which the numbers stop being the hard part and the scanning starts being the hard part.
What is the 20 second mode?
It is the game's second mode: a 20.0 second countdown that starts on your first tap, where the score is how far up the numbers you get before it runs out. The board keeps reloading past 50, past 100, up to 125, so in practice there is no ceiling. Really fast fingers get past 100. Most fingers do not.
How do I get faster at the number tap game?
Stop hunting one number at a time. Rest your eyes near the centre of the grid and let the whole board sit in your peripheral vision, so you find the next number while you are still tapping the current one. Move your finger, not your head. Practise in short bursts — the progress line on this page is there to tell you whether it is working.
