Latch - Logic Puzzle

Latch is a game of pure deduction. Every puzzle has one solution, and you can always reason your way to it - no guessing, no luck, no timers rushing you. Just you and a grid that rewards a clear mind. The rule is simple: Place one node in every row, every column, and every colored region - and no two nodes may touch, not even diagonally. From that single rule comes a surprising depth of logic. Mark the cells you've ruled out, place your nodes with confidence, and watch the solution reveal itself. What's inside: • 1,000 verified puzzles - every one checked for a single solution and a path of pure logic. Grids stay a comfortable size; it's the reasoning that deepens, from spotting a single forced cell to deductions spanning several regions at once. • A new daily challenge - one fresh puzzle every day, the same for everyone. • Build your streak - solve each day to keep your streak alive, and watch it climb. • Clear, uncluttered design - bright, distinct colors and nothing on screen but the puzzle. • Learn in a minute - a quick walkthrough teaches you everything; the depth comes from you. • Ads you can switch off - one small purchase removes the banner and between-level ads, for good. • Play anywhere, offline - no account, no sign-up, no connection required. No pressure. No randomness. Just the quiet satisfaction of a puzzle that always makes sense. Think you can solve them all?
