Motif puzzles were moved to /contrib/motif_puzzles. Unfortunately you will need Motif to compile. Unfortunately there are no self-solving algorithms with these. A record of moves is maintained of the best (or luckiest) performance. SLIDING BLOCK PUZZLES cubes: expanded 15 puzzle triangles: same complexity as 15 puzzle hexagons: 2 modes: one ridiculously easy, one harder than 15 puzzle ROTATIONAL 3D PUZZLES rubik: a nxnxn rubik's cube a 3x3x3 cube is available for Motif which does have a self-solver, standard notation, and one can shift perspective ftp.uu.net or ftp.wustl.edu /usenet/comp.sources.misc/volume37/magiccube pyramid: a nxnxn tetrahedron (a nxnxn pyraminx) with Period 2, Period 3, and Combined cut modes oct: a nxnxn octahedron with Period 3, Period 4, and Combined cut modes skewb: a cube with diagonal cuts
