Game 167 i.e today's game (www.chessguessr.com/games/167) cannot be solved because the solution requires black to skip one move.
ibb.co/S32SNqD

first move from white: Bxg5
first move from black: Rg6
second move for white: Nxg6

Now it is the turn for black to move but the solution requires white to move its rook: Rfe1

In the game (GM DrNyktertein VS IM BahadirOzen) the move played by black after Nxg6 is Nxg6 itself so that might have caused this bug.

Sorry about that, there was an error in today's solution until ~6:40 UTC. If you did get it wrong despite getting it right on move 4, we've cleared your guesses and you can try again.
