Math Solitaire Zero21

Rating: 4.9/10 - 9 votes

Solitaire Zero21 - How quickly can you solve basic math sums in your head? Play as one player in this straight-forward, challenging and addicting math card game for kids, teens and adults too. The history of this Solitaire game began with traditional Solitaire where you first remove all Jokers from the 54 cards and then you are given 4 random cards from the remaining 50 cards. In this version of the Math Solitaire game, you must get rid of all the cards and avoid reaching 21, using the addition and subtraction rules on the cards themselves!

The aim of the game is to use all of the cards but not exceed, or reach, 21. Use your mathematical knowledge to make sure you dont reach those heights with your numbers. Simple addition and subtraction is all that is required but do not take it too easy. This requires concentration as one wrong move can throw you off course. Play the cards strategically so you dont over shoot and end up with 21! Good luck!

How to Play: First of all pick your country out of the options then you are ready to start! Avoid getting to and above 21 in this game of solitaire. You must use your mouse to click on the deck of cards and then get them do disappear as you take one card at a time. The cards have a number on and either a plus or a minus which relates to how that card will affect the overall score. Once you use all of the cards, the game will restart with a fresh deck of cards. Enjoy!
