Number Chain: Logic Grid

Can you fill the entire grid — with every number in the right place?

Number Chain is a logic grid puzzle where you place consecutive numbers across a grid so that each one touches the last — horizontally or vertically. One path. No guessing. Just pure sequential thinking.

— HOW TO PLAY — A grid appears with a few numbers already placed. Starting from 1, place every number in sequence until the entire grid is filled. Each number must be directly adjacent — left, right, up, or down — to the number before it. No diagonal moves. No skipping. The chain must be unbroken.

Each level is handcrafted. Each has exactly one solution. No randomness. No luck.

— SMART FEATURES — • Intelligent hint system — each pointing to your optimal next move • Instant undo — backtrack without penalty, experiment freely • Full solution viewer — when you genuinely need it

— WHO IS THIS FOR? — Number Chain is for anyone who loves logic puzzles — especially if you've ever played Sudoku, Kakuro, Futoshiki, or any number-placement game. The rules take 30 seconds to learn. The later levels will take everything you have.

It's also a genuine brain workout. Sequential number puzzles develop working memory, spatial reasoning, and forward-planning ability. Five minutes a day is enough to notice the difference.

— NO FRICTION, JUST PUZZLES — No account required. No forced tutorial. No energy system. Download, open, and start solving. Level 1 is waiting.

The grid is set. The numbers are placed. The path exists — and only you can find it.
