A free, easy-to-play card game that uses numbers. A brain-training puzzle with simple rules. It feels great when you win or use a special card! -RULE The objective of the game is to remove all of the cards you’re dealt. You remove cards one at a time using numerical cards with 1-10 on them. You make connections using the cards 1-10, where the number can come before or after. e.g.) 7ー6ー7ー8ー9ー10ー1ー2ー1ー10 But you can only remove cards that are on top. Try and think about their order as you remove them. The game is cleared by removing all of the cards. There are four different game modes. --SIMPLE Play with GREEN cards only. --COLORS Play with three different colored cards, GREEN, BLUE, and ORANGE. Remove cards of the same color by their numerical order. --ENDLESS Play with three colored cards like in COLORS. In this mode you can’t remove all of the cards. When you remove some cards, new cards are added, and the game continues until you can’t make any more moves. If you use the Special Card that appears sometimes, you can remove all the remaining cards, and you’ll be given new cards to continue the game with. Plan carefully, and try to remove as many cards as you can. --THREE Match! You VS A.I. URL scheme numbersSolitaire://
