If Homer scored 400 points on the first try, he scored 400 - 70 = 330 points on the second try. The total number of points that Homer scored in the game after two tries are 400 + 330 = 730. On the third try of the Candy crush game, Homer scored twice the number of points she scored on the second try, a total of 2 * 330 = 660 points. In all the tries of the game, Homer scored 660 + 730 = 1390 points.
The final answer: 1390.
