Brain math game!

[Rule 1]. If three or more same numbers are attached horizontally / vertically 3 or more, we have earned a score.

(The amount of acquired score increases in proportion to the number size .ex.7 + 7 + 7 = 21, 1 + 1 + 1 = 3)

[Rule 2]. I calculate the touched number as the calculation item.

(However, computation can not be performed when there are no numerals whose computed values are 1 to 9.)

[Rule 3]. Given ten opportunities (count), if you earn a score, count increments by 1, and if you do not score, count decrements by 1. (When count reaches 0, the game ends.)
