Color Lines NG

A remake of the game "Color Lines" with a classic interface but using modern technologies.
Game rules:
The game is played on a 9×9 celled board where differently colored balls will appear.
Your goal is to get the highest score before the board is filled.
You earn points by making a line of 5 or more same colored balls either horizontally, vertically, or diagonally. The longer the line — the more points you'll get.
Each turn three balls appear in random cells of the game field, except on turns where you made a line of 5 or more same colored balls. In this case, the line of balls disappears.
To move a ball you need to tap it then tap an empty cell. The ball can't be moved if its path is blocked by other balls. Balls can only move horizontally and vertically.
Once the field is filled with balls the game ends.
You can also get bonus points if you disable the next colors hint (on the top) in the Settings menu.
