Play Online Blue Box
Blue Box is a puzzle where you move a little blue square from a green tile to a red tile. The screen is simple, so you can see everything without getting lost. You tap or press to slide the box in straight lines.
When the blue box moves over light-blue tiles, those tiles disappear. To win a level, you need to clear the right tiles and still reach the red goal at the end. If you move in the wrong order, you can get stuck and need to try again.
The first levels stay easy, but later ones make you think harder. There is soft music and no loud sound, so the game feels calm. If you like puzzles where you plan a path and watch it work, Blue Box gives you a neat, quiet challenge.
