Puzzler
(screenshot)
is a Windows program by Noel Dilabough. Puzzler plays all types of magic polyhedrons. Puzzler plays some 20 non-trivial variations of magic polyhedrons, including the five platonic solids with different cuts. The program is great, unique, but the interface is very bad. Extremely frustrating to use. Puzzler is a shareware.

Combine 2 squares together, you get a rectangle. That shape is called domino. Combine 3 or more squares together, the various shapes are called Polyomino. Combine several equilateral triangls, or regular hexagons, or any polygons, the generalized name for them is polyform.

Polyominoes is a polyominoes fitting game. Written by Kevin L Gong. In this program, you try to fit a set of polyominoes (connected squares) into a given shape. In another mode, two players take turns fitting polyominoes into a give shape. The first without a fitting piece losses. It's almost impossible to beat the computer. Mac, Windows and Java.

A arresting introduction to tangrams can be found in Time Travel and other Mathematical Bewilderments (1988), by Martin Gardner. amazon It includes a short bibliography.
Peg solitaire is a puzzle where there are a number of pieces on the grid, and you are allowed to jump a piece and remove piece jumped over. The goal is to leave just one piece on board.
★ Poly-Peg 1.09 (screenshot) by S T Han. This puzzle is sometimes known as peg solitaire. You remove pieces on a board by “jumping” other pieces over it. The goal is to leave only one piece on the board. PolyPeg lets you edit your own shape of square or hexagonal board and set whether diagonal jump are allowed in square board.

★ Poly-Off 1.09 (screenshot) is another excellent shareware by S. T. Han. The game Poly-Off can be thought of as one type of cellular automata. In a square or hexagonal grid, you switch on or off a cell that will affect neighbor cells. The goal is to switch off all cells. I had lots of fun with this program. For Mac OS and Windows.

★ Poly-Dol v.1.01 (screenshot) by S. T. Han. The puzzle in this program is similar to a commercial program named Cogito. You shift pieces on a board until all the pieces are in certain order. You can only shift pieces in certain row, column, or array of the board. There are dozen boards to choose for play and you can make your own board shapes. I find this program to be much fun.

★ Poly-Tile v.1.04 (screenshot) by S. T. Han. This puzzel is similar to a commercial program named Tesserae, published by In-Line designs Inc.
In this puzzle, Tiles of different design are layed over a board. You remove them one at a time by jumping (flipping) adjacent tiles of the same design. The goal is to leave only one tile on the board. I find this game too difficult. It's also hard to analyze because the random initial placement and designs. Like Poly-Peg and Poly-Dol, you can customize your board when you got bored with the given configurations. For Mac ＆ Windows. URL: http://members.aol.com/sth777/defaul.html
