Practice braille cells
Drill letters, numbers, punctuation and contractions until you recognise cells whole instead of counting dots. The wrong answers are drawn first from the cells one dot away from the right one, and the drill remembers which cells you miss.
What the drill covers
Braille does not stop at 26 letters. Four pools are drilled separately so you can work on whichever one is currently costing you, and each is the same table the reference page publishes.
| Mode | Cells | Reference page |
|---|---|---|
| Letters | 26 cells | the alphabet |
| Numbers | 10 cells | the digits |
| Punctuation | 8 cells | single-cell marks |
| Contractions | 19 cells | the groupsigns |
Both directions are available in every mode. Cell to name is the reading skill — you see a cell and say what it is. Name to cell is the writing skill — you are given the name and pick the cell.
The wrong answers are one dot away
With three random wrong answers the right one could be picked out without reading the cell. Every cell in the braille alphabet is some combination of the same six dots, and the cells most alike are those that differ by a single dot.
So the distractors here are drawn from the one-dot neighbours first. When the drill shows you E (dots 1 and 5), the alternatives it offers are drawn from A, D, H, O — each of which is one raised dot away. Getting that right means you read the cell. Guessing does not survive it.
Each letter page lists the same neighbour set for the letter it covers, so you can see the whole confusable group before you drill it.
What the drill is built around
The letters most alike are not neighbours in the alphabet: d and f are mirror images, h and j are mirror images, and m and u are both k with one dot added. Alphabetical order never sets them side by side.
So this tool drills contrasting cells, and the letter pages list each letter’s one-dot neighbours for the same reason.
It is built for short sessions: it remembers, between visits, which cells you miss and brings those back more often.
The drill trains recognition by eye. Reading by touch is a different skill, and needs embossed paper or a display; how to read braille by touch sets out what research and teaching sources say about it.
What the drill remembers
Every cell sits in one of five boxes. A cell you get wrong drops to box one and comes back most often; a cell you get right moves up a box and comes back less often. Reach box five and it counts as mastered, which is the number shown under the drill. The effect is that your time goes to the handful of cells you are actually failing rather than being spread evenly over cells you already know.
Progress is kept in your browser's local storage. There is no account and nothing is sent anywhere — see the privacy page. That also means it does not follow you to another device, and a private window starts fresh every time. The Reset progress button clears it.
When the drill starts feeling easy, the next step is reading connected text rather than isolated cells: try the decoder on a passage, or work through the phrase library where the same cells appear inside real words.
Questions and answers
How can I practise reading braille cells?
Drill letters, numbers, punctuation and contractions until you recognise cells whole instead of counting dots.
Why are the wrong answers so similar to the right one?
Deliberately. The wrong answers are drawn first from the cells one dot away from the right one, so the right one cannot be picked out without reading the cell, and the drill remembers which ones you get wrong.
