Invisible Choice by Thomas Riboulet

Invisible Choice is a force where a participant rolls a pair of imaginary dice but always winds up on the fifth item in a row or stack of (up to) 12. Like many techniques that use wordplay to produce multiple outs, there are outcomes that feel as fair as can be and others that need to be massaged in more or less fiddly ways. Careful scripting is supposed to minimize the chances of the most awkward options. But you wouldn’t want the same person to watch you do it more than once.
