Tametsi

Tametsi is a difficult logic game played on a set of tiles, in which you must use the clues provided to discover and mark hidden mines.

Notable features

• a variety of tilings beyond the standard square grid
  
  
• 100 increasingly difficult hand-designed levels
  
  
• 60 extra puzzles to unlock
  
  
• mid-level progress is saved automatically

Although Tametsi can be very challenging, every level can be completed using logic alone: guessing is never required.
