TrueWedge is a spinner wheel for meetings, classrooms, tournaments and raffles. It runs in the browser, needs no account, and shows no ads.
Its one rule is that the picture never lies about the odds. If a slice has a one-in-five chance of winning, it takes up a fifth of the circle — there is no mode that hides uneven weights behind slices drawn the same size. That constraint is the whole design, and everything else follows from it.
What does "honest geometry" mean?
A slice with a 20% chance of winning occupies 20% of the circle. Always. Many weighted wheels let you set uneven odds behind visually equal slices, so the picture disagrees with the maths. TrueWedge has no such mode, because a tool that lets you rig a draw invisibly is a rigging tool.
Can it draw without replacement?
Yes, and it is treated as a core use rather than an extra. Each winner is removed after the reveal and the remaining slices widen to show their new odds. Seeing the wheel change is the point: it is the honest disclosure that the odds moved.
Where is the randomness from?
The browser's cryptographic random number generator, with rejection sampling so that no outcome is favoured by rounding. The winner is chosen first and the animation is then solved to land on it, rather than a physics simulation being run to see where it stops.
Status
TrueWedge is being built. The wheel spins and the odds are honest; the reveal is still being designed.
