Making a track car desktop game from cardboard is a fun and creative way to make a game for yourself or your family. First, you will need to gather some supplies. You will need cardboard, scissors, glue, markers, and a ruler. Once you have all of your supplies, you will need to measure and cut out the pieces of cardboard that will make up the track. You can use the ruler to make sure that the pieces are all the same size and shape. Once you have the track pieces cut out, you will need to glue them together to form the track. Once the track is assembled, you can use markers to draw the lanes and other details on the track. Finally, you will need to make the cars. You can use cardboard, markers, and glue to make the cars. Once the cars are made, you can place them on the track and start playing. Have fun!
