Start with the traditional 15 puzzle, then have it replicate in all directions. Slide one cell down and see all the replicas also slide.

Need to find the number 3? You can use the one in the middle, up above, or down below, whatever is more close at hand.

The puzzle gradually gets more challenging as the levels progress.

What's a game without a theme and story line, am I right? Does this apply to a number slider puzzle? Ha ha, yep!

In-between levels there are intermissions to follow the adventures of 1, 2 and C.

Advance to the higher levels and discover some surprises.
