Rollic Games studio, specializing in easy-to-play and fun games with a sleek and minimalist design, launches this highly addictive card solitaire. Play with numbers and always stay between 0 and 21 to win each game.
A card mathematical challenge
Zero21 Solitaire presents a straightforward challenge. Players start with a central card with a number on it, and two or more additional decks, depending on the level. You always see the first card of each deck, which is a positive number, a negative number, or a special card. When you take one card from a deck, the amount will be added or subtracted from the center card number. Your goal is to keep that number between 0 and 21 until the deck runs out of cards.
Try to stay between 0 and 21. It's not easy!
To do this, you must use your wild cards and options wisely. When a letter does not suit you, you can leave it on the waiting stack for later use. You also have special cards that will reduce or increase your main card number.
You can also unlock several advantages by watching ads, but that kind of breaks the magic of the game. That is, you can get special cards and even remove cards from the decks if you are willing to watch some ads.
There are two game modes: levels and a daily challenge. In both, you can get prizes with which to unlock different decks of cards and personalize our experience. And if you don't want to wait, watch an entertaining ad and get a random card.
This is a very enjoyable solitaire style game with a minimalist and exquisite design. But you'll have a better time if you don't resort to that extra help.
