May XL-Month (5) - Blackout Domino

(Published on 31. May 2013, 12:00 by Richard)

My friday-noon-puzzles in May are all big; I have chosen five puzzle types that I have published before in the portal, and made bigger versions of these.

Blackout Domino
Paint some cells black and place all given domino pieces in the grid so that they don't overlap each other. Two orthogonal neighbouring cells from different domino pieces must be equal.

Black cells may not touch the border orthogonally and they may not touch each other orthogonally.

Solve online in Penpa+ (thx Nick Smirnov!)

Normal Blackout Dominos: Here and here.

Solution code: Row A, followed by row B. 'S' for a black cell.
