Sporos is a simple but well produced puzzle game to fill those brief spare moments. Each level is based on locating a number of infected cells in a hexagonal "grid" to infect the rest of the grid. The catch is that each cell provided infects only in particular direction(s), so that in order to cover the whole board, they must be located in the correct place. Different "labs" are also available as in-app purchases which feature additional special cells.

Sporos is a simple game but well executed with high-quality atmospheric graphics and sound. It will appeal to those who prefer to play in short bursts (each level typically takes from a few seconds to a few minutes). Those who prefer longer games will probably be looking for something with a bit more depth and variety.
