Dual
By Onduck Games
Dual hands you two orbs at once — one red, one blue — circling a shared ring, and asks you to keep both of them clear of the white bars drifting through the play area. Turning left or right rotates the pair together, so every move you make for one orb also moves the other. Made by Onduck Games, it plays free in your browser with no download.

How to Play Dual
You control a single circular orbit. Red sits on one side of it, blue on the other, and pressing left or right swings the whole pair around the ring. Because the two orbs are locked opposite each other, there is no way to save one without deciding where the other ends up — the game is about finding the angle that keeps both safe.
White bars slide across the dark, square-tiled background: short horizontal slabs, longer ones, and taller upright blocks as seen in the frames. Your job is to rotate the pair so the bars pass through the gaps rather than into an orb. The score in the top-left corner climbs while you keep going, so a run is measured by how long you can hold the pattern together.
There are no extra buttons or power-ups to manage. Two directions, two orbs, and a number counting upward.
Tips
- Watch the orb you are turning away from, not the one you are saving — the trailing orb is what usually gets caught.
- Small taps rotate the pair a little; holding a direction keeps it spinning, so use short inputs when a bar is close.
- Line the ring up so bars pass through the empty space between red and blue rather than trying to outrun them.
- Tall upright blocks cover more of the ring than the thin horizontal bars, so start positioning earlier when one appears.
Frequently Asked Questions
Is Dual free to play?
Yes. Dual runs free in your web browser with nothing to install.
Can I play Dual on my phone?
Yes. It supports mobile as well as desktop, and it is designed for landscape orientation. On a touch screen you tap the right side to turn right and the left side to turn left.
Who made Dual?
Dual was developed by Onduck Games and released in 2019, built with Construct 3.
Do I control both orbs separately?
No. The red and blue orbs are tethered on the same circular orbit, so one input rotates both at the same time.
How do I score points?
Your score shows in the top-left corner and rises as your run continues, so surviving the passing bars longer is what raises the number.
