Yes are you happy with the solution? Something bothered you with the wording which I didn’t understand...
You are a genius!
I would never have thought of your method, to decrease the difference by one for each test with bulb 1, so as to make up for the one more try with bulb 1...
This one’s serious....
The warden meets with 23 new prisoners when they arrive to prison. He tells them, "You may meet today and plan a strategy. But after today, you will be in isolated cells and will have no communication with one another.
"In the prison is a switch room, which contains two light switches labeled A and B. Both are in the “off” position now. The switches are not connected to anything.
All day long, I will be leading prisoners randomly, one at a time, into the switch room. Every time you’re there, you must flip one switch and you’ll then be led back to your cell.
There’s no limit how many times a prisoner will visit the room, and no particular order which I will follow. One might visit the room 3 times before another would be there even once, but with time, all prisoners will have visited the room the same amount of times.
At any given time, any prisoner may yell “all have visited the room!”
If that will be true, you’ll all be freed. If even one prisoner hasn’t been to the room yet, you’ll all be shot.
I will not purposefully hold back one prisoner from entering the room.”
What plan can they come up with to ensure that they’re freed?
Twist on this riddle:
In this scenario, what if the positions of the switches were unknown? How will the strategy have to be adjusted so that they can still be freed?

Well That was only after she claimed that 18 won’t do it. She tortured me into figuring it out.

You mean that you can see no difference between the "on" and "off" position in both of the switches, like it is the case with most switches today?
Or do you mean that there are two clearly identifiable different positions for each switch, but people do not know on which position it is starting the ordeal?

The prisoners are not told whether it's UP or DOWN.

I think she means that you don’t know whether they are on or off to begin with. In the original riddle you knew both started at off!
