0, 10 Ultimate Number Wheel
Eleven numbers sit on SpinyWheel's 0–10 Ultimate Number Wheel, not ten. It runs from zero through ten, giving each value a 9.1 percent chance instead of a round 10 percent. Rating scales, scoring drills, and anyone who needs zero as a real outcome spin it.
Why does a 0–10 wheel have eleven entries?
Counting from zero adds one. The range 0 to 10 contains eleven whole numbers because zero occupies its own slot, which drops the odds on every entry from 10 percent to 9.1 percent and widens each slice to 32.7 degrees.
That off-by-one catches people setting up raffles and scoring sheets, because "0 to 10" sounds like ten options right up until you count them. It matters whenever the odds have to be stated out loud:
| Wheel | Entries | Chance per number |
|---|---|---|
| 0–10 | 11 | 9.1% |
| 1–10 | 10 | 10% |
| 0–9 | 10 | 10% |
If you want a clean 10 percent, the 1–10 wheel is the version without zero. If you want zero on the board, the extra slice is the price.
What are the odds of landing on the same number twice?
Two consecutive spins on SpinyWheel's 0–10 Ultimate Number Wheel match 9.1 percent of the time, or roughly one pair in eleven. A specific number repeating back to back happens once per 121 pairs.
Spin five times without changing the list and about 66 percent of those sessions contain a duplicate, which is the outcome most people call a glitch. Seeing all eleven numbers at least once takes around 33 spins on average, three times the length of the list. The tail is the slow part: the last two or three numbers hold out far longer than the first eight.
Zero as a real result
Most scoring scales that people actually use start at zero, which is why a 0–10 range fits them without renaming anything. Net Promoter surveys run 0 to 10. Clinical pain scales run 0 to 10. A skills drill where the honest answer is sometimes "none" needs zero available, and a wheel that starts at 1 quietly removes it.
Spinning practice targets is the other common use. A coach spinning reps, a teacher spinning question difficulty, or a training app spinning a starting score all need the floor included. The how-to guide covers building a custom list if your scale runs somewhere else, like 0 to 5 or 0 to 100.
Drawing several numbers without repeats
Delete each result from the list before the next spin and eleven draws give eleven distinct numbers. Leave the wheel alone and five draws collide about two sessions in three, which is fine for a warm-up drill and useless for assigning eleven people to eleven slots.
Rerolling a number you dislike does the same damage more quietly. Reject anything under 3 and the remaining eight numbers each jump from 9.1 to 12.5 percent, so the wheel stops matching the odds you told everyone it had. For wider ranges the 1–100 wheel works the same way at 1 percent per number, and the tips page has more on setting up a list you will not want to argue with.
FAQ
Zero is a legitimate result on any scale that measures amount rather than position. Ratings, scores, counts, and tallies all need a floor of none. SpinyWheel's 0, 10 Ultimate Number Wheel keeps it as a full slice at 9.1 percent, the same weight as every other number, rather than treating it as a null result.
One extra entry. The 0, 10 range holds eleven numbers at 9.1 percent each, while 1, 10 holds ten at 10 percent each. Full coverage takes about 33 spins here against roughly 29 on the shorter wheel. Everything else, the pointer, the spin, and the result readout, behaves identically.
About 9.1 percent for any repeat, since the second spin has one chance in eleven of matching the first. A named number repeating, like two sevens back to back, happens once per 121 pairs. Streaks like that are what independent spins produce, and a long run without one would be stranger.
Yes. A 0 to 10 range already matches how most surveys and scoring sheets are written, so no relabeling is needed. Blind Mode helps if the group can see the screen and would otherwise anticipate the number before it lands, which is worth using when the score attaches to a person.
Set the range, spin, and take the number that lands. Zero counts.
