From Red Beard Foundry
A numberlink puzzle built around one idea — the puzzle should bend to you, not the other way around. 19,414 verified puzzles. You choose what to play, how hard, and where.
Draw a line between every matching pair until each cell of the grid is filled. Paths can't cross, can't overlap, can't branch. That's the whole rule.
Most numberlink games march you through one fixed ladder. Line Forge hands you the entire catalog and gets out of your way.
39 grid sizes from 5×5 up to 20×20 — 13 squares and 26 rectangular shapes. Every puzzle in the catalog was run through a reference solver and verified solvable before it made the cut. No filler, no dead ends.
Want a daily ritual? It's here. Want to dip in once and disappear? That works too.
Filter by difficulty — play what suits your mood, not what the game decides you've earned.
Pick your dimensions — quick 5×5 resets, mid-size boards when you want to settle in. The heaviest grids — 16×16 and up — arrive through the Weekly Challenge.
No locked levels. No "complete 12 to unlock the next pack." The browsable catalog is open from the first launch.
iPhone and iPad. Portrait and landscape. Every combination is first-class — the 20×20 weekly-challenge boards render cleanly on an iPhone SE, and a 5×5 feels right on an iPad Pro. Zoom and pan to see the whole board or focus where you're thinking.
Full Apple Pencil support on iPad. Draw your paths with Pencil exactly as you would with a finger — precise, natural, and built in, not bolted on.
Streaks, completions, and your place in the catalog sync across your devices. Put it down on the train, pick it up on the couch.
Three options, surfaced where you can actually find them: a metal track forged for the game, an atmospheric alternative when you want calm, or nothing at all. Mute is a first-class choice, not a setting buried four menus deep. Haptic feedback on every connection — on or off, your call.
Stuck? Your first hint each day is free. No countdown clocks, no fail states, no lives to run out. Play free with a light banner, or remove ads for good with a single one-time purchase. No subscriptions, no dark patterns.
Line Forge is built by Red Beard Foundry — a solo studio in Indiana making software with deliberate craft and an independent vision. Every puzzle solved and verified before it ships. The forge is the point.
