Card Match 10 is a card-merge game. A player's primary goal is to merge two or more cards layered on a two-tone green, diamond-patterned tabletop to clear it of a target number of cards that changes with each stage of the game. When they complete a stage, they receive points and coins.
At first glance, the cards looks like standard cards on one side, but they display numbers without suits on their faces. The game also features elements similar to solitaire-style free cell and pyramid games. Yet, there are significant differences.
At the bottom of the table is a brown frame made of six empty cells. The player pulls up to six cards from the table to merge in this area. To empty filled cells and continue removing cards, they must select cards that add up to equal a total value of 10. For example, they might select a 1, 3 and 8 and then select a 9 that results in the game automatically merging the 1 and 9 to create 10. Additionally, they might complete a straight of 1, 2, 3 and 4.
The player benefits the most in terms of points if they select the cards in an order that promotes consecutive automatic matches, such as selecting 1, 3, 4 followed by, without any interruption to the automatic adding by the game, 9, 7 and 6. Consecutive merges result in the game rewarding combination score points.
Card Match 10 also offers two boosters. The player can use a hammer to smash and erase any face-up card from the table or add extra cells to the frame by watching advertisements. Lastly, the player can use the coins they earn to upgrade their table theme.
