Card Match 10 is a small arithmetic puzzle: you tap cards to add them to your hand, and whenever the total reaches exactly ten those cards clear. Overshoot and you're stuck with the hand.
The whole game is in the counting ahead — knowing which cards are still available and which combinations remain. Stages clear when no cards are left.
The hand can't clear, which is the game's only fail state — so counting the total before each tap matters more than speed.
The maths is simple; the puzzle is planning which cards to save so that awkward numbers still have partners later in the stage.
Yes — tap the cards. Nothing to install.
