You are given a large collection of pieces of different shapes and sizes. Some of them are bigger than others, and some of them are smaller. All of them are mixed in a certain ratio, so it is impossible to determine their sizes and shapes. You have to assemble a real fire truck from these pieces.

The objective of the game is to create a picture of a fire truck. You can move the pieces around and zoom in to get a better look at them. You can also use a hint to help you in case you get stuck. The game is simple and fun to play, but it gets harder as you progress.

You can also change the shape of the fire truck by moving the pieces around.
