Today I played Shanghai for the 1st time on the Lynx.
Since the game doesn't seem to have levels, but the startlayout of the tiles always changes, I wondered:
Are the tiles mixed pure randomly or are they generated using an algorithm that takes care that they can be solved?
If they are just randomly mixed, then there are puzzles which can not be solved
In this game on other platforms, there are levels, which always have the same (solvable) stored layout ...
