The aim of LineIt is to earn points, as much as you can. You have to move jewel through free cells on the board. When 4 or more jewels with same colour will be connected in a row (horisontal, vertical or diagonal), these jewels will be deleted from the board and you will earn points (4 points for 4 jewels, 8 points for 5 jewels, 16 points for 6 jewels). New 3 jewels appear each time you move any jewel. Game over when there are no place for new 3 jewels.
