How to play Plus Minus Puzzle
- In the beginning you have 5 hand cards. The aim of the game is to reach a higher level.
- Drag the first card in the hand card area (bottom) to any card in the board area. When the hand card meets the card on the board, numbers on the board card will change to the sum of numbers on both cards.
- Three or more adjacent cards of the same number will trigger a triple- clear, and then merged to a new card with its number plus one.
- Upon each triple-clear, you will get a new hand card. You can hold up to 5 hand cards.
- When the quantity of your hand cards drop to 0, the game is over.
