How to play
Build a stable stack, clear lines, and outlast opponents by sending attacks while managing incoming pressure.
Your first few minutes
- Open Orbital Stack in a browser and choose solo, local split-screen, or online play.
- Read the falling piece and next-piece queue, then place pieces to keep the stack low and preserve workable lanes.
- Clear horizontal lines and build consecutive clears or combos without leaving isolated holes.
- In battles, watch incoming pressure, recover before the stack reaches the top, and attack when your board can absorb retaliation.
- For online play, choose Quick Match, Host and share a room code, or Join with a host’s code; use the result flow to rematch.
No reliable key-to-action map is supplied for published v5. Consult on-screen help or control labels; do not assume keyboard, touch, or gamepad bindings.
A little head start
- Keep the stack compact and preserve a flexible channel; repairing holes is safer than chasing risky clears.
- Clear decisively when garbage threatens the top, not only when a combo is available.
- Use local split-screen for practice; Host and Join are more predictable than waiting in Quick Match.
Before you start
- A modern web browser with JavaScript enabled.
- Online matches require a stable internet connection and another player.
