The App Store isn’t suffering from a dearth of puzzle games, so some rely on illustrated hooks or stories to draw players in. Sporos, on the other hand, presents a simple, no-frills presentation that puts the emphasis solely on the puzzles themselves. Placing the sporos pieces on a hex grid lights up the surrounding cells in patterns of straight lines, based on different configurations found on the pieces’ faces. Once you’ve lit up the entire board, you’ve completed the puzzle. This concept is easy enough to grasp, but the challenge quickly builds as the beehive patterns grow more complex corridors and the “Experimental” stages introduce arrow cells that divert the lines.
