Deca Merge is a casual puzzle number game. You will see multiple number cards from 1 to 9 arranged in overlapping layers. Your task is to eliminate them in sequence: any two number cards that add up to 10 will be merged and cleared, unlocking the cards they were covering. If no pairs can be cleared, you can tap the spare deck to reveal two new number cards. If the spare deck is used up and there are no combinable number card pairs left on the field, the game ends!
Deca Merge is a moderately challenging number game. You need to plan your merging strategy in advance and use your spare deck wisely to have a chance of clearing the board. If you fail a level, don't be discouraged—try again! Each new level is not a repeat of the last, offering a fresh challenge every time.
