How weights become slice sizes and odds

Every entry carries a whole-number weight between 1 and 20, and the wheel adds them together to get a total weight. Each entry's chance of winning is its own weight divided by that total, which is the percentage displayed next to it in the entry list. The slice drawn on the wheel is sized to match, occupying 360 degrees multiplied by the same fraction, so a visibly wider wedge really is a more likely outcome.

When you press spin, the wheel accelerates and then decelerates smoothly to a randomly determined resting angle. Whichever slice sits under the pointer when the animation ends is the winner, so the visual result and the underlying odds are the same thing rather than an animation played over a pre-chosen answer. Spin speed changes only how long the animation runs, not the probabilities.

If the option to remove the winner after each spin is switched on, the winning entry is deleted from the list once it has been drawn. The total weight then drops and every remaining entry's share is recalculated on the next spin, which is how a raffle-style draw without replacement behaves.

Worked example: a four-prize giveaway

Set up four entries with different weights: Grand Prize at weight 1, Gift Card at weight 2, Free Lunch at weight 3 and Bonus Round at weight 4. The total weight is 1 plus 2 plus 3 plus 4, which is 10.

The odds displayed beside each entry are therefore 10 per cent for Grand Prize, 20 per cent for Gift Card, 30 per cent for Free Lunch and 40 per cent for Bonus Round. On the wheel itself those become slices of 36, 72, 108 and 144 degrees, adding to a full 360 degrees.

Suppose the first spin lands on Bonus Round and the remove-winner option is on. Bonus Round is deleted and the total weight falls from 10 to 6. The odds for the second spin become 1 in 6 for Grand Prize, or 16.7 per cent, 2 in 6 for Gift Card, or 33.3 per cent, and 3 in 6 for Free Lunch, or 50 per cent. The slices redraw at 60, 120 and 180 degrees.

Both results are recorded in the spin history with the time they were drawn, and either can be copied as text.

Reading the odds without over-reading a handful of spins

Weights shift the long-run chances; they do not schedule outcomes. A 10 per cent entry has a 10 per cent chance on every single spin regardless of how many spins have gone before, so it can land twice in a row or not appear in forty attempts. Over ten spins, seeing a 10 per cent entry come up twice is unremarkable rather than evidence that the wheel is skewed. If your audience needs to see fairness, the displayed percentages and the visible slice widths are the thing to point at.

For a genuine raffle where nobody should win twice, switch on the option to remove the winner after each spin. Leaving it off means every spin is independent and duplicate winners are expected, which is right for prize wheels but wrong for drawing names.

Two practical points. Weights are whole numbers from 1 to 20, so express fine-grained odds by scaling everything up rather than reaching for fractions: three entries at 2, 3 and 15 give 10, 15 and 75 per cent. And the spin history is a list on the page with a clear button, so copy anything you need as a record before you clear it or leave.

Frequently Asked Questions

Each entry's chance is its weight divided by the total weight of all entries. With weights of 1, 2, 3 and 4 the total is 10, so the odds are 10, 20, 30 and 40 per cent. The slice on the wheel is drawn to match, so wider wedges genuinely win more often.
Yes. The import option accepts pasted lines, so you can copy a column from a spreadsheet or a list from a document and add every line as its own entry in one step. Each imported entry starts with the default weight, which you can then adjust individually if some need better or worse odds.
Turn on the option to remove the winner after each spin. The winning entry is deleted from the wheel once drawn, the total weight falls, and the remaining entries share the odds between them on the next spin. That produces a draw without replacement, which is what raffles and name picks normally need.
The wheel settles on a randomly determined angle and the slice under the pointer is the winner, so the animation and the outcome are the same event. Changing the spin speed to slow, normal or fast alters only how long the animation runs; it has no effect on which entry comes up.
It records each winner in order with the time it was drawn, which is useful when you are running several rounds and need to announce or verify results afterwards. There is a button to clear the list, and individual results can be copied as text, so save anything you need before clearing.
