If my understanding is correct, "seven steps" has to be replaced by "seven spins". What do you mean?

 See #2: seven spins, not seven steps  The wheel turns anticlockwise. Or the arrow turns clockwise.  What does mean: "there is a set of unwinnable numbers"? "There is at least one set" or "there is exactly one set"?

If I replace "clockwise" by "anticlockwise" it is possible to confirm the three unwinnable sets of the example.

From the example it seems clear that the intended meaning is that the arrow moves clockwise around the wheel.

I'm pretty sure the intended meaning is "infinitesimally small". That is, the phrasing is only intended to indicate which of the two sectors is the one removed, not meant to imply that any finite multiple of it would ever reach the size of a full sector.[/QUOTE]
That's the only interpretation making sense. Otherwise the puzzlemaster had to concretize the "a little less than one number"  0,9999 or so. q will become very big.

In example 1 of the wheel with q = 5: 1 round removes the 5 2nd round remove the 3 3rd round removes the 8 and remains 1,2,3,6,7 The next round is the 7 which will jump. .... But what I don't understand is example 2. "a set of k numbers unwinnable"? Last fiddled with by Kebbaj on 20210405 at 15:26
