Cube Rush 3D — Offline Stacking Game

Stack cubes, dodge the cutters, reach the flag. A 3D stacking game that plays in your sidebar — fully offline, no sign-up.

Cube Rush 3D is a complete 3D stacking game that lives in your browser's side panel. Click the toolbar icon and it opens beside whatever you are working on — no new tab taken over, no page to navigate to. Steer down the street, collect every cube you can, and grow your stack. Run it into a cutter and you lose the cubes above the cut, so the whole game is a running decision about greed: one more row, or get what you have to the flag. Coins from each level buy upgrades — a taller starting stack, a wider magnet, longer bridges over the gaps. WORKS WITH NO INTERNET The entire game is inside the extension. The 3D engine, the levels, the music and the art all ship in the package, so it runs on a plane, on hotel wifi, or with the network off entirely. Nothing is streamed and nothing is fetched while you play. PLAYS IN THE SIDE PANEL It stays open while you switch tabs, so a round survives you going back to work for a minute. Your level, coins and upgrades are saved locally between sessions. ARROW KEYS OR MOUSE Steer with the left and right arrow keys, or drag with the mouse. There is no tutorial to sit through — the first level teaches it in about ten seconds. NO ACCOUNT, NO ADS, NO TRACKING There is no sign-up, no advertising, and no analytics of any kind. The extension asks for one permission, "sidePanel", which is what lets it open the panel. It requests no access to your browsing, your tabs, or any website you visit.
