It is a game where the aim is to help a person named Biip find a way to recharge his own spaceship to return home. To give instructions to Biip, you must drag the boxes representing the actions towards the tape in the correct order.
Basically it is an example of how it works to write commands when it comes to programming something. Although the levels are simple at first, the complexity goes up a lot in recent levels of the game. Accounts with 20 levels can be completed in order or randomly selected whenever you want.

You can also create your own levels of the site, because it contains an editor that lets you compile your puzzles with all the same tools that the game uses.
You can save these levels and share them with other people through the icons created by the level editor. This part is more interesting to improve your logical skills.
