Random Roulette Spinner

Start by putting the candidate list in view

The left pane is where you add, remove, or replace the choices. The right pane shows the canvas wheel and the current result, so everyone can see what will be drawn before the spin starts.

• Use 2 to 30 choices.
• Short labels are easier to read on the wheel.
• The recent history only lives in the current browser view.

Manual entries fit meetings and daily decisions

Type custom entries for presenter order, coffee runs, game penalties, chores, or trip ideas. After adding an item, use the remove button beside the row if the list needs a quick correction.

• Duplicate names are allowed but can confuse interpretation.
• Avoid private names on a shared display unless everyone agrees.
• Turn long sentences into short labels before spinning.

Presets are only a quick starting point

Lunch, team order, and yes-no presets fill the wheel with familiar examples. Pick a preset, then edit it for the actual group, meal choices, or decision question instead of treating the sample list as fixed.

Repeat pattern fills ordered slots quickly

A pattern such as A,B,C can be repeated across the number of slots you choose. It is useful for rotating duties, group turns, classroom roles, or seating cycles where the same labels repeat.

• Only comma-separated values become wheel entries.
• Blank values are skipped.
• The slot count is clamped to the 2 to 30 range.

Example: choosing a team presentation order

Enter Team 1 through Team 6 and spin once to pick the first presenter. Record the result, remove that team from the list, then spin again for the next slot. The tool draws one result at a time; it is not a full tournament scheduler.

• Remove already picked teams when you need no repeats.
• Adding the same team twice gives it two wheel slots.
• History is a reminder of recent picks, not an official record.

Random selection still has limits

When supported, the page uses crypto.getRandomValues; otherwise it falls back to Math.random. That is practical for casual choices, but it is not an audited random-number process.

• The page does not guarantee fairness.
• One copy of each choice gives the intended equal slot count.
• Duplicate entries intentionally increase the chance of that label.

The wheel animation is a visualization

The spin helps people follow the moment of selection. The code chooses one entry from the current list and animates the wheel toward that result, so speed, color, or slice position should not be read as a probability proof.

Full screen is for shared viewing

Use full screen when a room, class, or video call needs a larger wheel and result. The same choice list is used, and the close button or Escape key returns to the normal page.

Reset and history keep the session tidy

Recent results help during a short series of spins. Clear the history or reset the wheel when the topic changes, and copy important outcomes into a separate note if they need to be kept.

Agree on the procedure before important spins

For assignments, priority order, or money-related choices, decide who is included, whether duplicates are allowed, how rerolls work, and when an option is removed before pressing Spin.
