A visual way to pick a random letter
Plenty of games and activities need a random letter — 'name a country starting with...', alphabet-based icebreakers, or letter-of-the-day classroom activities. A wheel makes the pick visible and adds a small bit of suspense compared to a plain instant random-letter generator.
Type A through Z (or any specific subset of letters) into the entry box once and reuse the same wheel across rounds or sessions.
