The puzzle starts with two random numbers between 2 to 9 in an empty 6x6 grid. When you drag a number in the empty slots in the grid, all matching numbers are removed and total is added to your score. After each drag 2 more random numbers are added to the available empty slots. The game ends when all slots are filled.
Hint: In each turn try to remove as many numbers as possible. Higher numbers should be removed on priority.
