Preview a game
The preview runs your working game so you can test changes before committing a version for other players.

Try a change
- Open the game's preview and choose a valid player count. Done when the initial position appears.
- Change the viewed player, or choose the spectator view when available. Done when you have checked what each viewer is allowed to see.
- Try a phone-sized viewport as well as a wider one. Play a complete turn. Done when the controls fit and the game advances correctly.
- Restart when you need a fresh position. Review any rebuild options offered after editing. Done when the preview reflects the saved source.
Framework differences
TypeScript previews support named checkpoints. Framework preview games use a local replay record and their own restart and rebuild controls. Follow-active-player controls change which seat you view; they do not replace testing hidden information from each seat.
Previewing does not publish or commit a game.
