"Number 7" Game

Number 7 is a logic game with unusual gameplay. You need to move cells with the same digits to assemble a block of three elements. At the same time the cells will unite and give as a result one cell with a bigger digit. For example, match three cells with the digit 1 and get one cell with the digit 2. As the game progresses new cells appear on the field and you can match more and more digits to get to 7. This is the maximum number in this game that will give you a bonus. You must keep matching cells to get cells with the number 7 until all cells are filled with sevens. It's a simple game, but it's not easy to complete. You will need all your logic and strategic thinking to move the numbers as efficiently as possible. If the field is filled with numbers that can't be moved and matched, you lose.

Move a numbered block to another cell.
Merge three or more numbers to get higher numbers.
‘7’ is the final number. When you make it you get a bonus!
