Zero21 is a thrilling card strategy game that challenges your mental agility and risk management skills. Your objective is simple: collect cards to clear the field while ensuring your running total never drops to 0 or rises to 21. Every move counts in this highly addictive and challenging browser puzzle.

We offer you to play from the card with a virtual opponent. The task is to prevent getting a value of twenty-one or a point from the cards that you will collect at the bottom of the screen. In this case, you must clear the field of cards. Collect them one at a time, taking into account the restriction above.
