Tinta: Color Sudoku Logic

300 grids with one single solution, always reachable through pure logic. No timer, no lives to lose, never an ad in the middle of a grid. Tinta is sudoku with the numbers fired and colors hired. Every grid hides a secret coloring — and everything, absolutely everything, can be deduced. Zero luck, zero guessing: if you're stuck, the answer is already staring at you. HOW IT PLAYS • Tap a cell, it changes color. Congrats, you know the rules. • 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. • A few cells start revealed: your footholds. • Hit Check when you're ready. Fewer tries, more stars. Simple. Cruel. Addictive. IT ESCALATES • 300 levels generated and verified by a logic engine: one unique solution, always reachable through pure reasoning. • Three worlds: 4×4 with 3 colors to warm up, then a fourth color, then the 5×5 that bites. • Up to 3 stars per level — a perfect first try is the real trophy. • And every grid resumes exactly where you left it. STUCK? NO JUDGMENT • The logic hint highlights the next deducible cell — figuring out why is on you. • Reveal colors one correct cell to get you rolling again. • Earn coins by solving levels (or by watching an ad, if you feel like it). MADE FOR HUMANS • No timer, no lives, never an ad in the middle of a grid. Your brain deserves the quiet. • Purist mode: turn off the correct-cell counter and play without a net. • Color assist: a distinct symbol per color, so you never depend on color alone. • Soft, warm interface, dark mode included, one-time Remove Ads purchase. Into sudoku, binairo (takuzu) or nonograms? Tinta is your next coffee-break obsession. One grid, one coffee, let logic do the talking.
