Latch vs Barndoku!

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?

Barndoku is a logic puzzle with the rules of sudoku and the charm of a farm. Every board is a grid of coloured pens. Place exactly one animal in each row, each column and each pen, and never let two animals touch, not even at the corners. That's the whole rulebook. The thinking is in working out where an animal can't go, fencing off those cells, and watching the last possible spot reveal itself. If you enjoy star battle, sudoku or any one-per-row logic puzzle, you'll feel at home in the barn. HOW A PUZZLE PLAYS • Tap a cell to fence it off when you know no animal can live there. • Double-tap to place an animal when only one spot remains. • Boards grow from a 4×4 warm-up to 10×10 brain-benders. • Stuck? A hint points at the next deduction. A reveal shows a cell outright. Both refill every hour. A LITTLE EVERY DAY • Daily Streak: solve one puzzle a day, keep the flame alive, earn prizes on day seven. • Leaderboard: each solve lays eggs. Climb past the other farmers before the day resets. • Daily Challenge: one big board shared by everyone, with your finishing time ranked against the crowd. MAKE IT YOURS • Every animal you reveal for the first time unlocks it as your face, with its own frame. • Pick a handle, wear your favourite face, and see your name on the board. MADE FOR GROWN-UPS WHO LIKE A THINK No timers on the ladder, no lives, no penalties for taking your time. Pattern Mode swaps the colours for patterns if that reads better for you. No sign-up.
