So If you are aware of the angel problem, I propose a Variant: we introduce the Sticker Devil: A normal devil, with the added ability to sacrifice his turn to color any and all White Tiles that are neighboring at least two Black Tiles. Does the Devil now have a winning strategy?

  • $\begingroup$ If "neighbouring" includes all the cells a 1-power Angel (aka a chess king) can move into, then almost certainly. But you probably used "neighbouring" to mean "orthogonally adjacent to"? $\endgroup$

  • $\begingroup$ No I meant king style. So the former. $\endgroup$ Jun 15 at 8:26
