Puzzle
This little app is a simple
scramble square puzzle. Each piece contains the top or bottom half of a colored triangle on each side.
The objective is to re-arrange the pieces such that all halves match up to form full, monochrome triangles.
The puzzle may seem simple, but consider that the pieces can be arranged in 9! x 4
9 = 95,126,814,720 ways.
While there are several solutions — for example, rotating any solution by 90 degrees results in another one —
randomly positioning the pieces is unlikely to provide a quick solution, so a systematic approach is needed.
The puzzle always starts in a random configuration. Any two pieces can be swapped via drag and drop, and each
piece can be rotated (90 degrees clock-wise) by double-clicking. There are buttons to create a new random
configuration, to save or load a configuration, and to automatically solve the puzzle (the search strategy
mostly ignores the start configuration).
