A one-line logic puzzle. Draw a single unbroken line from 1 to the last number, touching the numbers in order, filling every open cell. Three rules, 150 hand-picked levels across six chapters, and a last chapter where the line you find is the only one that works.
Fifty levels free. One payment for the rest. No ads, no account.

This repository hosts Sikku's public website (GitHub Pages). It is plain hand-written HTML with no build step and no dependencies.
The board in the hero is playable: it is level 14 of First Light, drawn as SVG
and driven by a port of the app's own rules. Only that one level's checkpoints
are inlined — never paste in levels.json or tools/levelgen/thread-prototype.html,
because both carry all 150 levels and a view-source would give the game away.
The palette mirrors Shared/Theme.swift in the (private) app repo, and the
rules, banner strings and haptic weights mirror GuideSheet.swift,
PuzzleScreen.swift and Feedback.swift. If any of those change, update
index.html to match.
