Combining
The hexagonal grid is held up by six posts. By swiping, you will raise one of the posts and all the tiles will slide in the direction you swiped and will travel as far as they can go across the grid.
When the tiles finish moving, connected sequences of tiles will combine. To combine, the highest numbered tile will increment by one and the remaining tiles will disappear. If one of those tiles contains an egg, the egg will hatch and the baby sea turtle will follow the numbers down to the 1 where it will drop into the ocean. Your goal is to hatch all the eggs in the level to advance to the next level.
