"Marble Race and Gravity War" is a simulation game that can work in two modes. The modes are best represented by the questions that are answered by the final result of the marble competition. And these are the following:

1) Which country will touch the "winner" banner first?
2) Which country will be the last on the racing board?

The balls representing the countries will start randomly from the empty space at the top of the racing board. Below them is a brick wall. The balls bouncing on the bricks gradually break down the wall. In the first mode, the country that touches the "winner" banner first wins. And in the second, the one who stays on the racing board the longest wins.

Starting the simulations is the "Why one is first?" and "Which is the last?" with buttons. It does not require human intervention while running.

In the "Options" menu, you can set the number of countries competing on the racing board, which can be between 25 and 75. By default, 50 countries will compete.

In the "Your favorite country" menu, you can choose your favorite country, which will be indicated by a white circle drawn around the marble on the racing board.
