Battle Spirits Saga Simulator: Solitaire

Welcome to BSSDB's BSS Simulator!

Improve your skill by practicing Battle Spirits Saga against yourself.

This feature has no awareness of card effects. Because of this, the simulator allows you to do things that are not allowed by the rules, but allows them because it has no idea when active effects might allow you.

While this Simulator works on phones (in landscape), the size of UI elements can make it quite difficult to play depending on your device. Fear not! I will be releasing an alternative UI shortly that makes it easier to play on a phone.

While I do plan to add some multiplayer aspects, I don't intend to implement full game rules or card effects. This "Simulator" is only designed to allow simple gameplay like or Tabletop Simulator. Battle Spirits Saga is a game that belongs to BANDAI. While I hope they see the value this Simulator can bring to the game and community, ultimately it's their right to control their game as they wish, and I certainly intend to respect those wishes.
