Object: Tile the square board with copies of the given shapes.
The tiles on the right side of the 40x40 board are rotated and/or enlarged versions of a decomino, i.e. a polysquare made from 10 squares.
Click one of the images to select a tile. Click the board to place it. The 'sweet spot' of the tile is always located at the end of the 'handle'.
You win if you can cover the board with these tiles without gaps or overlaps.
Variants 2 to 9 : cover the given white area without gaps or overlaps. Variants 5 and 6 show the same shape to be filled. However, in variant 5 you must tile the given area using ony ONE size of tiles (either only the large ones or only the small ones). In variant 6 you must tile the given area using BOTH sizes of tiles.
The puzzle in variant 1 is taken from my book 'A Puzzling Journey To The Reptiles And Related Animals', 1986, one of three books on geometrical problems and puzzles I have privately published. For details see my web page. Variant 1 demonstrates the 'rectifiability' of this special decomino. It also shows that this decomino is an irregular rep-tile or 'irreptile', which means that it tiles a larger version if itself, if we allow the tiles to have more than one size. Shapes of this type are the central topic of the book. More freeware as well as real puzzles and games at my homepage http://karl.kiwi.gen.nz. |
