Unsolvable puzzle?


I’d like to report an unsolvable puzzle and request that it be marked as such:


It’s one of Brourd’s, made for a bet I didn’t want to agree to. He can probably testify himself about the unsolvability.

Hi drake178,

Thank you for the pointer. We’ll ask Brourd about the puzzle and take down the puzzle if necessary.

I’ve made a screenshot for you. I considered just making an unsolvable puzzle myself, but then decided not to mess around :smiley:


It works by deleting the last couple bases in a lab puzzle then undoing and then redoing it, that last step enabling you to recolor a few of the last ones. All you need is a shape that needs a color downstream of a stack in a multiloop, this is a perfect one.
