The queen moves and takes along straight lines and diagonals, as far as she likes, but she cannot jump. In this drill you tap every black piece the white queen could capture right now. Find them all and the next board appears.
Get five boards in a row right for a silver star and ten in a row for gold. A wrong tap shows you the answer and starts your count again. Harder levels hide pieces behind other pieces.
Tip: trace each of the eight lines from the queen and stop at the first piece you meet. That piece can be taken; anything behind it is hidden.
