TapAllBalls

This app is a game where you tap and erase multiple balls arranged geometrically.

All you have to do is tap to erase the balls, but the restriction on the order in which you erase them makes the game interesting.

Rules.
- You can start with any ball
- You should not go over balls that have not tapped yet
- You should not go slantwise
- You can go to the distant ball
- You can go through places where you have tapped a ball
- You should not return

Interesting as a deciphering puzzle
In simple stages, you may reach the goal by accident, but in more complex stages, you have to find the correct solution by omitting the route one by one logically.

The Interest of 3-Dimensionalization
It's complicated by the 3-dimensionalization of the ball placement. In 2D, everything can be grasped at a glance, whereas in 3D, it is difficult to grasp the whole picture. It is necessary to rotate the stage and look at it from various angles to figure out its placement. Of course, there are also two-dimensional stages.

Tutorial
There are a few rules, so I've created a tutorial to illustrate them.

There are quite a few levels of difficulty
The difficulty of the game is roughly proportional to the number of balls you have. When you increase the number of balls, the stage usually gets bigger, but if the stage is too big to fit on the screen, the balls get smaller and the operation gets worse. I'd have to design the game within its operable range, but even the limits of the operability made the game difficult enough. As a result, I handle a wide range of easy to difficult stages.

One type of solution
If you create a stage with the rules above, there is not a single solution for every arrangement. Many stages with multiple solutions are also generated. However, I have tried to adopt many of the one type of solution methods. It's also interesting to realize that there's only one way to solve a puzzle when you're solving it.

The reason for creating it
This game is based on an old puzzle called "Goishihiroi", which is a puzzle played with Go stones on a board. I found it quite interesting, so I considered making it into an app. But someone else had already made another one. I thought I'd add something new and came up with the idea of making it 3-dimensional. Even if the rules were the same, I felt that 3D would make it even more interesting. I started development.
