## What is Masyu puzzle?

Masyu is popular puzzle game in Japan.

Masyu is played on a rectangular grid of squares, some of which contain circles; each circle is either "white" (empty) or "black" (filled). The goal is to draw a single continuous non-intersecting loop that properly passes through all circled cells. The loop must "enter" each cell it passes through from the center of one of its four sides and "exit" from a different side; all turns are therefore 90 degrees.

The two varieties of circle have differing requirements for how the loop must pass through them:

White circles must be traveled straight through, but the loop must turn in the previous and/or next cell in its path;
Black circles must be turned upon, but the loop must travel straight through the next and previous cells in its path.

## Key features

- Draw a continuous loop
- Pass through all circled cells
- White circle rules
- Black circle rules
- 90-degree turns
- Rectangular grid

### 1/5 — Frustrating

*2021-07-30*

All of the puzzles are the same difficulty, so the only challenging part is getting the unbelievably terrible controls to work. The app also crashes sometimes for no reason.

### 2/5 — Crashes frequently and controls are bad

*2019-11-21*

The app crashes frequently during use. Fortunately, progress is maintained so it’s easy to go back to the level.

The controls don’t appear to support drawing a continuous line. Instead each segment must be drawn individually.

After completing a level, you’re taken back to the start screen rather than to the level select.

With some fixes, this could be a fun puzzle app but as is, the crashes make it a lot less fun.

### 1/5 — Poorly designed

*2019-04-22*

Crashes often, annoying to use. Better off just using an online puzzle generator.

### 1/5 — Not so good for precision...

*2019-02-01*

I’m sorry to say this, but the colors clash in the background, and when I completed it, it wouldn’t say anything like ‘You Finished!’, and such. One last thing, when I tried to connect the lines, it was slightly laggy and difficult to do with precision.

### 1/5 — Crashes

*2018-06-13*

Crashes...
