Solitaire Zero 21 is a new take on a familiar classic. Despite what the name might suggest, the game has little to do with the more familiar Solitaire games. The objective here is to collect all of the numbered cards from the board. Every time a card is selected, its value is subtracted from (or added to) the total. Choose the cards wisely to emerge victorious – it’s best to keep the total as close to 10 as possible, but sometimes it’s worth taking a chance! Complete a round to earn gems and proceed to the next one. Click on the cards to play them
