Object: Tile the given shapes with Y-Pentominoes. (6 variants)
 
The puzzles have an unlimited number of the Y-shaped pentomino. These can be used to exactly cover the given fill-in area.
 
See the description in the downloaded package for instructions on how to handle the tiles.
 
One of the game variants allows you to play freely with the Y-Pentominoes. Here you have no win condition.
 
Note that you can also redesign the fill-in area in all variants in order to create your own tiling problems.
