Latch vs Cubdoku

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?

Cubdoku is a cozy logic puzzle built around one simple rule set and an adorable bear cub mascot. HOW TO PLAY Place exactly one cub in every row, every column, and every colored region — and make sure no two cubs ever touch, not even diagonally. Mark cells you've ruled out with an X, use auto-marking to skip the busywork, and let the puzzle click into place. Easy to learn in under a minute. Genuinely hard to master as the boards grow from 5x5 up to 10x10 and the difficulty climbs from Easy to Expert.
