Cardgame Sandbox is a single-player tabletop card simulator from yistar1. It gives you a browser workspace for creating decks, importing cards, arranging play areas, and testing custom card-game rules without sending your data anywhere. The focus is not racing or reflex action: it is a flexible sandbox for building and playing your own card systems.
How to Play Cardgame Sandbox
- Open the play mode, choose or import a deck, and set up the table area.
- Drag cards between zones, hands, discard piles, and board spaces as your rules require.
- Use the workshop and settings screens to adjust game pieces, layout, and card behavior.
- Experiment with different rules until your custom card game feels ready to play.
