For experienced nonogram players, the Old Masters pack contains a dozen black & white collage puzzles. From collages made up of four puzzles all the way up to 25, altogether you'll have to work your way through 200 individual puzzles based on classic art by the Old Masters.

If you have the default  Club Piczle House Blend puzzle theme selected, the background music while playing these puzzles will be replaced with some relaxing, classical pieces.

And if you manage to clear every single puzzle in this challenging puzzle pack in Challenge Mode, you'll unlock the Old Masters Master sticker to adorn your profile with!
