Click on any number on the board to select it. Then, click on another number that is directly next to it (either horizontally or vertically) to create a connection. The selected numbers will merge into one with a value that is double the original number.
No, the numbers are fixed on the board. You can only move the board by clicking and connecting numbers to create new numbers or to match existing numbers.
When you connect three of the same numbers, they will merge into one with a value that is triple the original number. This new number can then connect with other numbers and merge again, increasing your score.
Increase your score by creating longer chains of the same numbers. The longer the chain, the higher the value of the new number created, leading to a larger score.
Theoretically, there is no highest score since you can keep creating larger and larger numbers by chaining them together. However, the game board has a limit, so you'll need to manage your space efficiently to keep playing and scoring points for as long as possible.
