ThinkGrid: Calm Logic Puzzles

Eleven logic puzzle types, a new daily in each, six difficulties from a coffee break to Grandmaster. No ads, ever.

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. No prior knowledge needed for any of the eleven.

NO ADS, EVER

The free tier is complete: every game, every daily, four difficulty tiers. There is no advertising anywhere in ThinkGrid and there never will be.
