I’ve posted a switches puzzle here.

I was thinking of a easier setup which is “static”.
Mine has a 65535 possibility setup, but you can make an easy puzzle with below setup.

Set D3 to
pinMode(D3, INPUT_PULLUP);

Notice that I’ve placed the wires for some switches at the bottom, so these switches need to be set in the other direction “off” than the others.
Only 7 switches matter, you could use all of them.
When using a switch with only two connections, place the switch upside-down. Now OFF is switch with ON.

ON	?	?	?
?	OFF	ON	OFF
?	?	OFF	?
?	OFF	?	?

is the correct setting
