Tinta: Color Logic Puzzle

About

One grid of colors, one single solution, and everything can be deduced. No timer, no lives, never an ad in the middle of a grid. Just you, your logic and a pencil. Tinta is a color deduction puzzle, a cousin of sudoku, binairo (takuzu) and nonograms. Every grid hides a secret coloring. Zero luck, zero guessing: if you're stuck, the answer is already staring at you. HOW IT PLAYS • Pick a color from the palette and tap a cell to fill it. Tap it again to clear it. • Count chips tell you how many cells of a color sit in a row or column. • The = and ≠ markers link two neighboring cells: twins, or rivals. • The pencil rules out impossible colors, cell by cell. Eraser and undo are there when you change your mind. • Grid full and right? You win. If something's off, we'll tell you, but not where. THE DAILY PUZZLE • A fresh grid every day, the same for everyone: 5×5 early in the week, 6×6 on Thursday and Friday, 4 colors on Saturday, 7×7 on Sunday. • Play day after day to grow your streak. • Share your result (stars, mistakes, streak) with zero spoilers. • Missed a day? The last 14 stay playable. • A daily reminder if you want one, at the time you choose. 360 GRIDS, FROM 4×4 TO 7×7 • All generated and verified by a logic engine: one unique solution, always reachable through pure reasoning. • Progress through worlds: first steps in 4×4, then 5×5, 6×6 and 7×7, with 3 or 4 colors. • Up to 3 stars per grid: no mistakes and no hints is a flawless solve. • Every game picks up exactly where you left it. STUCK? WE'LL EXPLAIN • A hint doesn't just fill a cell: it shows you one and tells you why. "This row already has its 2 pink cells: this cell can't be pink." • 3 free hints every day, plus 2 more for watching an ad, only when you ask. • Live check fades out satisfied count chips and turns anything that breaks a rule red. It follows the rules, never the solution. Purists can switch it off. MADE FOR CALM • No coins, no shop, no timer, no lives. • Ads are rare: never during a grid, never before level 20, never after the daily puzzle. And a one-time Remove Ads purchase gets rid of them for good. • Color assist: a distinct symbol per color, so you never depend on color alone. • On iPhone and iPad, dark mode included, playable offline. One grid, one coffee, let logic do the talking.
