Eleven logic puzzles, no ads
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
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.
