Cubic Coil

Mission briefing

Guide a green-black voxel snake inside a rotatable cube. Spin both snake and cube to line up moves, collect voxel fruit squares and rare big fruits for bonus points. Classic Snake rules, reimagined in 3D with a crisp green backdrop.

Field manual

PC: Rotate cube with WASD. Steer snake with Arrow Keys. Mobile: Swipe on the left side to rotate the cube; swipe on the right side to steer the snake.

Launch orders: press Launch mission above and the game loads on this page itself — nothing downloads and no form stands between you and the first move. It is designed for a landscape (wide) screen and takes its orders from mouse, keyboard or touch, depending on the mission. It is built wide, for a landscape screen — rotate a phone sideways, or give it a tablet or monitor to stretch out on. If it offers a fullscreen control, use it — a fight this size deserves the whole screen.

Field notes for .io arena operations

• Eat at the edges. The centre of an .io arena is where the giants feed; the rim is where small players grow fat on leftovers nobody bothers to chase.
• Never chase a smaller player in a straight line for long. Every second of pursuit is a second the whole arena can see, and something bigger is always watching the chase instead of the chased.
• Use your size as a rumour, not a shield. The moment you make the leaderboard, you become content for everyone's evening — spend big size on safety, position and patience.

Cubic Coil — questions from the ranks

What does it cost to play Cubic Coil?

Nothing at all. The mission is free from the first order to the last — no sign-up, no download, no paid tier guarding the good levels. The advertising around this page is what keeps the board free.

What sort of mission is Cubic Coil?

Cubic Coil is filed in our .io Arena theatre. Like every operation on this board, it is a browser game — read the briefing above for the publisher's own account of what you are deploying into.

Can I run Cubic Coil on a phone or tablet?

Yes. It plays in the browser on phones and tablets exactly as it does on a computer. It is built wide, for a landscape screen — rotate a phone sideways, or give it a tablet or monitor to stretch out on.

Do I have to install anything before playing?

No installation of any kind. Cubic Coil is an HTML5 game: press the launch button and it loads on this page, and closing the tab leaves nothing behind.
