Sliding Blocks #839

#839 · Oct 19MediumArchive: not ranked

How to play

Drag a block into empty squares, or tap it and use the arrow buttons. Blocks slide in straight lines and never pass over each other.
Bring the big red block down to the gap in the bottom edge of the tray: it slides out and the puzzle is solved.
Sliding one block any distance is one move, and sliding the same block again straight after (round a corner, say) is still that move. The fewest possible is shown.
Fewest moves wins, then the fastest time. Easy trays take about 8 to 18 moves, medium 24 to 45, and hard days use a taller tray and 50 moves or more.
