Seven (SevenSlider)

3D slider puzzle for children, but surprisingly tricky even for adults. Helps learn 3D problem solving skills. Similar in concept to the 2D "fifteen" slider puzzle. Written in Ada, this code compiles and runs on Windows, OS-X and Linux. Now, improved function on laptops; runs on OS-X Retina displays too. New mousewheel zoom.

Too easy, you say? Try the 3x3x3 Rufas' Cube!

Anyone with GNAT may recompile; but first try the delivered exes. Note for Mac users: now includes a Mac binary bundle.

Minimum system requirements: 

Windows, Mac OS-X or Linux with graphics card that supports OpenGL v 3.3
