In Zauberfl ache, you are in control of a 5×5 big playfield, which is
randomly filled with five squares of five different colors at startup. On each
side, there is an arrow to move the entire row one square to the left, right,
top or bottom (whereby the playfield is a 2D torus – you move left and come
back right, same for top and below).

The goal is simple: arrange the playfield so that there are 5 identically
colored horizontal or vertical lines. The game counts both the moves used and
the time needed to complete a stage.
