Tametsi

Tametsi is played on a set of tiles, some of which have mines hidden beneath them. Your goal is to determine which tiles have mines and which tiles are safe. Safe tiles will reveal how many neighboring tiles have mines. There is no guesswork in Tametsi: every puzzle can be solved through logic alone. Hone your deductive skills across 100 increasingly difficult hand-designed levels. (griptopgames.com)
