Object: Tile the given shapes with the 12 Pentominoes tiles. (25 variants)
 
The twelve Pentomino tiles consist of all polysquares with 5 squares.
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 Pentominoes. Here you have an unlimited number of each tile available.
 
Note that you can also redesign the fill-in area in all variants in order to create your own tiling problems. You can even create two separate areas side by side (also see variant 6).
 
 
Much material has been published on polysquares.See for example:

• the book 'Polyominoes' by Solomon Golomb 1994
• the book 'A Puzzling Journey to the Reptiles and Related Animals' by Karl Scherer 1987, privately published
• many articles in the Journal of Recreational Mathematics etc
