Column Clash FAQ

How do you win Column Clash?

Connect four of your discs horizontally, vertically, or diagonally before your opponent does.

Can two people play on one device?

No. Multiplayer is two people on two different devices (Public or Private). Single player is you versus the CPU.

Is this the same as Connect Four?

It is an original InstantGameBox implementation of the connect-four loop — original name, art, and code. We do not use Hasbro branding.

Does Play go fullscreen?

Yes. Native fullscreen first, CSS fallback on iOS. Back restores the landing page.
