About Solitaire 0 - 21
Solitaire 0 - 21 is a number-card puzzle built around a simple but important limit. Your task is to collect every card from the board while keeping the running sum between zero and twenty-one.
Special cards give you ways to control that total when ordinary number cards make the calculation less comfortable. With seventy-five unique levels, the game combines the familiar card-collecting feel of solitaire with ongoing arithmetic decisions.
How to Play Solitaire 0 - 21
Collect all the number cards shown on the board.
Keep your current sum at least zero and no higher than twenty-one.
Use MIN, MID, or MAX cards when you need to set the sum to their corresponding value.
Plan each selection so the next card does not push the total outside the allowed range.
