Opening the cargo ark…
Cratebound
Walk, push, pull and route every rune crate onto its matching dock.
0 / 30Every crate and device is deterministic. Read the route, preserve turning room, and use magnetic pulls only when they recover a stranded cargo block.
Six chapters introduce ice rails, signal gates, magnets, linked crates and one-way belts.
Walk, push, and pull rune cargo through thirty authored sky-ark warehouses.
Rux is restoring a cargo ark one warehouse at a time. Every rune crate must reach a glowing dock before the route can reopen.
Move one square at a time and push crates only when the cell beyond is open. Magnetic Pull moves Rux backward while drawing an adjacent crate into the space Rux left.
Later chapters add sliding ice rails, signal gates, linked cargo, and one-way storm belts. Each device follows a fixed, readable rule.
Thirty warehouses span six chapters: First Freight, Polar Rails, Signal Deck, Magnet Bay, Twin Cargo, and Storm Ark.
Every warehouse is authored and solvable. Undo and Restart let players test a route without losing cleared-stage progress. The complete interface uses one centered logical layout with a 920-pixel maximum. Phone, landscape, and desktop views scale the same controls, hit areas, artwork, and game coordinates together instead of stretching individual pieces. Touch, mouse, and keyboard therefore act on the same legal state. The Main poster and Start Game action remain separate from Stage management, while Stage selection, Battle, dialogs, and Result keep their own bounded content and return path.
You can play without creating an account. Progress is saved in local browser storage on the current browser profile, not in an online account or cross-device database. Clearing site data, using private browsing, changing browsers, or moving to another device can create a separate save or remove the existing one. Language, sound, and reduced-motion preferences follow the shared WeightPlay controls when the browser permits storage. No guide result is a medical, school, or professional assessment.
Dock every rune crate without trapping it.
Move beside cargo to push it. Pull moves you backward while drawing the adjacent crate into your previous cell.
Your completed progress is safe. This attempt will restart.

Every cargo block reached its dock.
