Adapting games to the miniature screens and limited processing power of mobile phones is quite a challenge. To accommodate these technical limitations; mobile games are often twodimensional (2D); tile-based; and seen from above. Such games rarely present much creativity with respect to dynamic lighting. Textures are merely plastered onto the tiles. A recent game release has; however; shown that effects such as dynamic light sources can spice up a mobile game of this type quite a bit. In this paper we carry the idea of dynamic lighting effects for tile-based 2D games even further. In particular; we present simple and efcient techniques for shadows and uctuating fog which can greatly improvethe gamers visual experience.
