What's Up at OSS!

Not at all! The rules guide you through legal card sequences, so anyone can learn as they play. If you train BJJ already, you'll enjoy recognizing some of the real moves and strategies.


The game is recommended for 12 years old and up.


OSS! CARD COMBAT provides a pleasant card experience, utilizing a good quality card stock with a protective low-gloss UV coating that gives a pearl-like luster and makes cards slide easily. The printing quality is also high, ensuring clear and concise designs for game cards and other printed materials. 


 Key Aspects of OSS! CARD COMBAT Quality

  • Card Stock: Good quality card stock that is comparable to the stock used in many popular game cards. 
  • Coating: A low-gloss UV coating is applied, which adds durability and prevents a harsh glossy glare. 
  • Printing: The printing ink quality is high, ensuring that colors are vibrant and designs are clear. 
  • Feel: The low-gloss finish contributes to a smooth, pleasant physical feel for the cards. 
  • Durability: The UV coating helps protect the cards from wear and tear, making them more durable for frequent use.

This game is designed for 2 to 4 players.


OSS! Card Combat™ came from the idea that Brazilian Jiu-Jitsu positions, having such clear and defined starting and ending positions, could be used as a game mechanic when playing cards from Takedown to Submission.


OSS! Card Combat™ was built from the ground up with real Brazilian Jiu-Jitsu research. Every move and transition was validated for accuracy to reflect realistic chains that grapplers actually use. 


The game was playtested literally on the mats with real BJJ practitioners, ensuring that the flow of the cards matches the flow of the art. Beyond authenticity, we put in hours of card balancing and probability testing to guarantee fair and exciting gameplay.


The end result is a game that’s not only fun but also a unique way to sharpen your “jiu-jitsu brain.”
