DashMash.io

Mission briefing

DashMash.io is a chaotic multiplayer obstacle race where up to 10 players battle it out in real time! Jump, dash, and dodge your way through stages packed with moving platforms, swinging hammers, crumbling blocks, and deadly spikes. Each round cycles to a brand-new map, forcing you to adapt on the fly. Reach the finish line first to claim the top spot on the leaderboard — if the chaos doesn't get you first!

Field manual

Race to the finish in this frantic multiplayer platformer! Navigate through obstacle-filled stages alongside up to 9 other players in real time. Dodge hazards, ride moving platforms, and unleash your dash to surge ahead of the pack! Desktop Controls: ← / → (Arrow Keys or A/D): Move left and right. ↑ (Up Arrow) / W / Space: Jump — double jump supported! Shift: Dash — burst forward for a speed boost. Mobile Controls: On-Screen Joystick: Drag to move left and right. J Button: Tap to jump. D Button: Tap to dash forward.

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 flexible screen and takes its orders from mouse, keyboard or touch, depending on the mission. It adapts to both upright and wide screens, so phones, tablets and desktops all frame it sensibly. 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.

DashMash.io — questions from the ranks

What does it cost to play DashMash.io?

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 DashMash.io?

DashMash.io 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 DashMash.io on a phone or tablet?

Yes. It plays in the browser on phones and tablets exactly as it does on a computer. It adapts to both upright and wide screens, so phones, tablets and desktops all frame it sensibly.

Do I have to install anything before playing?

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