Number Chain

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. Download Number Chain free today.

Verdict
The clearest difference is in-app purchases: Number Chain at none against Echo Zone's 1. Number Chain also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.1). On price, update cadence and device support there is nothing between them.
