About ThinkGrid: Calm Logic Puzzles
Eleven logic puzzles in one app. No ads, no timers, no energy bars — just a grid and the part of your brain that likes being asked something. THE PUZZLES Suguru — fill each cage with unique numbers Star Battle — place stars so no two touch Masyu — loop through black and white pearls Nonogram — reveal the picture from row and column clues Color Link — connect matching colors and cover the board Hashi — connect islands with bridges Light Up — place bulbs to light every white cell Kakuro — fill runs with digits that sum to each clue Fillomino — fill the grid so each number group has the right size Tents — pitch a tent next to every tree Bomb Digger — deduce where every mine is hidden Every puzzle is generated with a unique solution and is solvable by logic alone. You never have to guess. A NEW DAILY IN EVERY GAME Eleven daily puzzles, one per game, every day. Keep a streak, track which games you return to, and see your solving habits build up over the months. SIX DIFFICULTIES Easy, Medium, Hard, Expert, Master, Grandmaster. Easy is a coffee break. Grandmaster is not. LEARN ANY OF THEM Each game has a step-by-step guide that plays out on a real board, one move at a time, explaining why each move is the only one that works.
