## What is Moon?

Moon-or-Sun is logical puzzle game.
Draw a line to make a single loop following the rules.

1. A rectangle, bordered by bold lines, is called a "room". The loop goes through each room only one time. Once the loop leaves a room, it cannot return to enter this room.
2. In each room, the loop goes through all of the moon cells or all of the sun cells. The loop cannot pass through both moon cells and sun cells in one room.
3. After the loop goes through the moons in one room it has to go through all the suns in the next room it enters and visa versa.

We prepared more than 10000 puzzles in this app.
Of course, you can play the all puzzles without the payment.

### 4/5 — Love it but one little flaw!

*2016-11-17*

Just like all your other puzzle apps I absolutely love it! There's one small little flaw though. The game doesn't check if you properly filled all the boxes so a small 'square' going through two countries is enough to trick it into 'winning'.
To achieve this, just make a closed loop that goes through a sun country and then a moon and then connects back up to the sun.

Otherwise brilliant app!
