Card Merge has simple game mechanics that are very easy to understand.

In this puzzle game, you will be given four stacks of cards.

Each stack will have cards showing numbers on them.

Your job is to combine cards with the same numbers on them.

You can do this by dragging a card and dropping it on top of another card with the same number on it.

Afterwards, the number shown on the card will double.

You can drag a card towards another receiving card even though there are other cards on top of it. But you will need to bring the cards above it to the stack of the receiving card.

As the numbers get bigger, finding combinations might start to become more difficult.

Therefore, the higher the numbers, the more difficult it would be to beat your own top score.

This game will keep you entertained for hours and hours...
