How to play Square 3D
Press play and the first round teaches you the rest. You will want a keyboard for this one — the arrow keys / WASD carry most of it, and the table below has the rest. Portrait layout: hold the phone the way you normally do, or play it centred in the page on desktop. Nothing is lost by trying something reckless once.
Controls
| Input | Action |
|---|---|
| Mouse | Navigate menus and interact |
| Arrow keys / WASD | Move |
| Spacebar | Primary action |
On mobile: Tap and swipe directly on the screen. The game is built for portrait, so you can play one-handed without rotating your phone.
Why it is worth playing
