A wheel that agrees with you
Every spinning wheel on the internet promises fairness. This one promises the opposite, and says so on the tin. You type a list, you tell it which entry should win — or which entry should never win — and it obliges, while looking exactly like the fair wheel it is built from. Same wedges, same slowing arc, same little burst of confetti at the end.
There are two rigs, and they are not equally useful. “Always lands on” is the obvious one and the weaker one: the third time the wheel produces the same name, the room works it out. “Never lands on” is the rig that actually holds up. The wheel lands somewhere different on every spin, the results look completely unremarkable, and yet one particular entry never comes up. Nobody audits a wheel for absences.
Two details make it usable in front of people. The controls collapse to a single unlabelled button, because a rigging panel visible on a projector is worthless. And the rig follows the entry rather than the wedge position, so you can shuffle or re-sort the list while everyone watches — which looks like the most transparent thing you could possibly do — and the same name still wins. Delete that name and the wheel tells you it has gone back to a fair spin instead of silently re-aiming at whoever took the slot.
The movement is not faked either. The wheel takes a different number of turns each spin and stops at a slightly different point inside the winning wedge rather than dead centre, because landing in exactly the same place is the one thing that would look wrong. It is the same spin engine the fair wheels on this site use, with one extra instruction about where to finish.
Nothing is stored. The list, the rig and the results all live in the page, no account is needed and reloading resets everything to a fair spin. Which brings us to the part worth being blunt about: this is a party trick and a teaching prop, and using it to run a draw that people believe is fair is not a clever hack, it is deception. There is a plain wheel spinner on this site with no rigging controls in it at all. If the outcome matters to anybody other than you, that is the one to open.
