The time machine will ask us a question that has been answered for a year. We will have to write the year and a color code will help us guess the year. The faster you answer correctly, the more points you get.

Different questions will appear to us, the answers to these questions will always be one year. We will travel through time instead of guessing the event year of different events, inventions and actions. We will have to enter the year, as if it were a code, in a code box. But we will not be alone, when placing the numbers, a color code will tell us if each entered number is in that code or not, and if it will be in that or another place written when we are about to be. Thus, if we do not know the answer, we can guess the answer through different attempts. Once we put the year right, a brief information about that event, invention or action will appear.
