Spin the Wheel — Random Name Picker for Trainers

Spin the Wheel solves the small problem every facilitator has twenty times a day: who goes next. Type the names — everyone in the group, discussion topics, prizes, anything — once, open the wheel on the projector, and hand the decision to the draw. A six-character code puts the same wheel on every screen in the room; no accounts, nothing to install.

Names are the usual use, but the entries can be anything: discussion topics, group tasks, energiser games, prizes at the end of a workshop. The wheel stays flat and every name stays upright — Burmese included — so the whole room can read it from the back row.

Fairness is built into how the spin works. The winner is chosen by the server with a cryptographic random draw and written into the spin history before any device learns the result; the flickering animation is only there to make the moment enjoyable, and every screen in the room settles on the same stored name at the same time. There is nothing to argue with — the draw is on the server, not on anyone's phone.

Turn on "drop each winner" and the wheel becomes a fair rota: each winner leaves the hat before the next spin, so everybody presents once before anybody presents twice — the last name in the hat is still drawn normally, and only once everyone has been picked does the wheel refuse to spin again instead of pretending to draw. Every spin is kept in a history list, which is enough to settle any argument later, and the wheel deletes itself after seven days.
