Zero 21 is a strategic, number-based HTML5 card game by DoonDookStudio that blends simple rules, focus, and smart decision-making into a relaxing yet challenging experience.
Players draw number cards and drop them onto the main card, carefully keeping the total sum between 0 and 21. Go above 21 or below 0—and you lose. It sounds simple, but every move requires attention and planning.

With intuitive drag-and-drop mechanics and clean, easy-to-read visuals, the gameplay is simple to understand but difficult to master. Each level challenges players to think ahead, manage risk, and maintain balance while collecting all the number cards on the board.
Zero 21 Solitaire delivers engaging, brain-training sessions that combine the relaxing feel of solitaire with the excitement of number strategy—making it ideal for fans of card games, logic puzzles, and mindful challenges. This game’s similar version on Google Play has over 1K downloads.
