  In this paper we introduce an imperfect information variant of the Angel and
Devil game, which was first introduced in 1982 by Berlekamp, Conway, and Guy.
The Devil player has a winning strategy in this game, but the main problem they
pose is whether this changes if the Angel player is allowed two moves for every
one of the Devil. This and many other variants of the game have been
considered, and the original question was only solved in 2007, when it was
shown that the so-called power 2 Angel could win. Our main theorem, Theorem 4,
is that the Devil player wins the imperfect information variant of the game.
This generalizes the result that the Devil player has a winning strategy in the
original Angel and Devil game.
