Kolo dopisů

It's genuinely random. The pick comes from the Web Crypto API — the same secure source browsers use for encryption keys — so a rare Z or Q has exactly the same chance as a common S or T. Nothing nudges it toward the easy letters.

Yes. Tap off whichever letters you don't want and the wheel spins what's left. Vowels-only is handy for a phonics lesson; consonants-only ups the difficulty in a word round. You can also type a tiny custom set when you're teaching just two or three letters.

Remove each letter after it's drawn. The next spin then pulls from the remaining ones, so a long Scattergories session or a whole-class alphabet exercise can run with no repeats until the wheel empties out.

It does. The letter wheel installs as a progressive web app, so once it's loaded the first time it spins offline — useful in a classroom with patchy WiFi, a quiet library corner, or a car with no signal on a long drive.

They can. The result shows as one big letter rather than small text, and you can set it to uppercase or lowercase to match the books they're reading. Spinning is a single tap in the middle — no menus to get lost in.

It works well for it. Spin a letter and have learners name as many words as they can that start with it, or build a sentence around it. The random prompt keeps practice from drifting toward the same handful of familiar words every session.
