Letter Picker Wheel

1. What This Tool Actually Does

Underneath the animation, this is a random letter generator: click Spin, and JavaScript's Math.random() function picks a number that maps to one letter slice on the wheel. The spinning motion is there to make the wait feel earned and the result easy to read from across a classroom — it doesn't change which letter you get.

Where this differs from a plain text-based letter randomizer is control and memory. You choose which letters are even in play (vowels, consonants, or a hand-picked set), and the tool remembers what's already come up in a given session through the frequency heatmap, so you're not relying on your own memory to notice a pattern — or the lack of one.

2. How to Use It

3. Vowels Mode vs. Consonants Mode

Vowels mode loads just five letters — A, E, I, O, U — so each one has a flat 20% chance per spin. With only five wide slices, the wheel is easy to read from the back of a room, which is why it gets used for phonics drills, rhyme games, and early-reader vowel-sound recognition.

Consonants mode loads the other 21 letters, each at roughly 4.76% per spin. It's a common choice for consonant-blend practice — spin twice in a row and combine the results into a blend like BR or ST — initial-sound warm-ups, or a denser spelling-bee style challenge where the slow-down at the end feels more suspenseful.

4. Custom Mode — Build Your Own Set

Custom mode gives you all 26 letters as toggle buttons. Start from All or None, or load the Vowels or Consonants preset and adjust from there, then click Apply to push your selection onto the wheel. This is where the tool earns its keep for anything with unusual constraints — a Scrabble tile pool missing certain letters, a phonics group working on a narrow set of sounds, or a spelling list with a handful of trouble letters.

5. The Odds: How Random Is Each Spin?

Every slice on the wheel is drawn the same size, so the odds are simply 1 divided by however many letters are active — no letter is weighted to appear more or less often. Here's what that works out to for each mode:

With Remove After Pick switched off, the wheel has no memory: each spin draws from the full active set again, so a letter that just came up is exactly as likely to come up next time. Turn Remove After Pick on and the pool shrinks by one letter after every spin, so the odds for whatever's left rise slightly each time — by design, since the point of that mode is to eventually hit every letter exactly once.

6. What People Actually Use It For

• Word-game warm-ups: spin for a starting letter before a round of Scrabble, Bananagrams, or a word-association game
• ESL and early-literacy classrooms: spin a letter and have students name an animal, food, or country that starts with it
• Writer's-block breakers: a random letter prompt for naming a character, a place, or the first word of a scene
• Vocabulary drills: spin, then produce as many words as possible starting with that letter in a target language
• Party and group games: spin for a letter and give everyone 30 seconds to name five things in a category that starts with it
• Phonics and blend practice: Vowels mode for vowel-sound recognition, Consonants mode for blend drills
• Puzzle and grid games: generate a random letter pool for crossword clue-writing, anagram challenges, or a Boggle-style board

7. Reading the Heatmap, Stats & History

Letter Frequency is a 26-cell grid showing every letter and how many times it's shown up this session — cells glow gold once they've been hit at least once. It's a fast way to see whether results are spreading evenly across many spins, which makes it handy for a live probability demonstration in class: run 40 or 50 spins and let students watch the heatmap fill in.

Session Stats distills the same data into three numbers — total spins, how many distinct letters have appeared, and which one has come up most. Spin History logs each individual result in order, newest first. All three reset together when you click Clear History & Stats, and also reset automatically if you reload the page.

8. Saving Your Setup & Sharing It

Your chosen mode, and your exact letter set if you're in Custom mode, is written to your browser's local storage automatically, so it's still there the next time you open this page in the same browser. That's a setup preference, not a spin result — nothing about the outcome of a spin gets saved.

Click Share Wheel to copy a link with your mode and letter selection encoded into it. Open that link on any device and you get a wheel configured the same way — useful for handing a specific practice set to a co-teacher or teammate — but the actual spin each person gets is independent and won't match yours.
