On the Subject of Switches

A manual choice isn't too bad. Unfortunately you never know ahead of time which one will be your next.

Switches need to be flipped to match the lit indicators either above or below them.

There are however configurations to be avoided. Switches are numbered 1-5 from left to right. A configuration lists the numbers of the switches that are UP, any switch not listed is DOWN. Avoid the following switch configurations:

• 3
• 245
• 2345
• 14
• 145
• 1345
• 12
• 124
• 123
• 1234
