Fun solitaire where you have to juggle numbers

The Rollic Games studio, known for its simple and very entertaining titles with a clean and minimalist design, offers us this quite addictive card solitaire. Play with numbers and try to stay between 0 and 21 to win every game round.

A math challenge with cards

The challenge presented to us by Zero21 Solitaire is quite easy to complete. We start with a main card with a number and two or three stacks depending on the level. We always see the first card on each deck, which is a positive number, a negative number, or a special card. When you draw a playing card from one of the decks, the sum shown on it is added to or subtracted from the number on the main card. Our task now is to keep this number between 0 and 21 until the cards of the deck end.

In order to achieve this goal, we need to use the wild cards and the available options in a clever way. If we don't like a card, we can add it to the queue to use later. We also have special cards that reduce or increase the number of the main card.

On the other hand, we also get several benefits by watching advertisements, which, however, disrupt the game's magic a bit. This means that if we allow ads, we can purchase special cards or even remove cards from the decks.

There are two game modes: level and daily challenge. In both of them we can purchase prizes that will allow us to unlock different decks of cards to personalize our gaming experience. And if you don't want to wait, randomly get new ones by watching a nice ad.

All in all a very entertaining solitaire style game with a clean and premium design. But you'll have more fun if you don't use the extra help.
