The aim of this game is to simulate a waterfall using numbers. The waterfall is considered well-formed only if:

- The sum of the numbers that form the waterfall is equal to the goal.

- The marked numbers should be adjacent horizontal, vertical and diagonally. That is, there is no empty line union.

- There are 2 numbers marked on each row.

Also available a challenges section, where different challenges and variations of the game appear. In both cases, there are two levels: normal and difficult. In the normal level, the sum of the waterfall numbers is shown, however, in the difficult level, you will have to sum them mentally because it disappears.

Sum and subtract. Sharpen up your mind.

This game is compatible with Android Wear

这个游戏的目的是模拟使用数字瀑布。瀑布都被认为是结构良好的前提：

- 形成瀑布的数字的总和等于目标。

- 被标记的数字应该是相邻的水平，垂直和对角线。也就是说，没有空行结合。

- 有标注在每行2号。

同时还提供一个挑战部分，在这里不同的挑战和游戏的变化出现。在这两种情况下，有两个级别：正常和困难的。在正常水平，瀑布数的总和却显示，在困难的水平，你必须在精神上总结他们，因为它消失。

总和减去。锐化你的心。

本场比赛是与Android Wear兼容
