A game to find a path to erase all balls by tapping them. There are rules for the order of erasing. Rules. - Do not go slantwise - Do not go back the route you came. 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. In-App Purchase - Additional stages - The function to record the stages you have started - Remove the ad 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.
