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.
