Radial 3D
Mission briefing
Join the thrilling adventure of Radial 3D, where you explore space while controlling a black hole. Your goal is to absorb celestial bodies, avoid dangers, and ascend through the cosmos. This free game challenges your skills on both mobile and PC. How far will you go?
Field manual
Move the Black Hole – Move the mouse.
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 portrait (upright) screen and takes its orders from mouse, keyboard or touch, depending on the mission. It is built tall, for an upright screen — a phone held normally frames it best, though any window will run it. 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.
Radial 3D — questions from the ranks
What does it cost to play Radial 3D?
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 Radial 3D?
Radial 3D 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 Radial 3D 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 tall, for an upright screen — a phone held normally frames it best, though any window will run it.
Do I have to install anything before playing?
No installation of any kind. Radial 3D is an HTML5 game: press the launch button and it loads on this page, and closing the tab leaves nothing behind.
