## What is Latch?

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:

• A growing run of puzzles - start small and work up through larger, richer grids as your reasoning sharpens.

• 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.

• Clean, focused design - a calm, uncluttered board with nothing between you and the puzzle.

• Learn in a minute - a quick walkthrough teaches you everything; the depth comes from you.

• 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?
