Plain game mechanics are simple but fast and i think the cards flip with a tap to reveal a pair that you must match quickly before they vanish again.
Tap the cards to flip them, you must remember their spots fast.
Controls are taps and clicks with no extra buttons. There are no stated features like timer, hints, toggles, modes, levels, or difficulty.
Most tip i discovered is to tap the cards fast and remember where they are because the cards won’t stay visible long. Practice your timing to beat your high score.
