How was this game won??

Played a game of chess and was declared winner, as far as I can see, black still has valid moves, anyone see anything I don't? Thanks

if white to move as it says then Re7 is mate

if its black to move then moves like Re8 stopping the mate drop the rook on f2

and your a piece up already..

Where did you play this game of chess? There are no games in your archive here on chess.com.

Last move was white bishop from g5 to h4, that was it, white was declared winner.

It was on Ipod touch, chess with friends

It's possible black resigned or ran out of time (if it's a timed game). Other than that it's possible there is a bug on Ipod touch, chess with friends. I don't see how anyone on this site could answer this question for you.
