I've stared at this forever, and I can't figure out why it isn't looping. Everything works fine, except it isn't looping. Maybe it's that I've been staring at it too long, and I need a new eye and keep overlooking it.

Common ways to figure this is out is to simply use debugging techniques. For small problems and programs like these, a simple cout statement or printf statement or even cerr redirected to a log file or the console would do just fine.
Do simple things like print choice variable after it's been set to the said input. Because choice is most likely not 5, the loop will fail for whatever reason.
Also, code like
1 2 3
int s;
s = slots();
s;
is EXTREMELY bad practice. This could be easily optimized and made more readable by doing int s = slots();. That and s; in your code is a waste of CPU since it does absolutely nothing.
