Line Forge is a numberlink puzzle game built around one idea: the puzzle should bend to you, not the other way around. Draw a line between every matching pair until each cell of the grid is filled. The rule is simple. What's different is everything around it. Forge your line. Your way. Most numberlink games push you through one linear progression. Line Forge gives you the whole catalog and lets you choose what to play, how to play, and where. A new puzzle every day if you want a daily ritual. One large puzzle per week if you want a fight. - 19,414 verified puzzles across 39 grid sizes — squares from 5×5 to 20×20, plus 26 rectangular shapes - Daily Puzzle — a new fixed puzzle every day, the same grid for everyone; build a streak - Weekly Challenge — one large puzzle per week from the heavy-end pool (16×16 and up) - Filter by difficulty — pick what fits your mood, not what the game decides for you - Pick your dimensions — small grids for a quick reset, mid-size grids when you want to settle in - iPhone and iPad, portrait and landscape — every device and orientation built as first-class, not retrofitted. 20×20 grids fit on iPhone SE; 5×5s feel right on iPad Pro - Zoom and pan — see the whole board or focus where you're thinking - Sync across your devices — start on your iPhone, finish on your iPad. Streaks, completions, and your spot in the catalog follow you - Set the sound — a metal track forged for the game, an ethereal alternative if you want quiet focus, or no music at all; mute is a first-class choice, not a buried setting - Hints when you need them — first one each day is free; no manufactured paywalls Independently forged. Line Forge is built by Red Beard Foundry — a solo indie studio in Indiana making software with deliberate craft. Every puzzle in the catalog has been solved and verified before it ships. The forge is the point. No ads between puzzles. No timer pressure outside the weekly challenge. No dark patterns. Remove ads with a one-time purchase if you want, or play free with light banner support. Forge your line.
