Flip the coin. If you get heads, move one space/step/circle forward. If you get tails, move two spaces/steps/circles forward.
-There are circles on the board. In each circle, there is an expression or a piccture.-
(Are they correct? By the way, which side is heads and which side is tails?
On one side there is a number. On the other side, there is a statue of a famous person.)
On US coins, one side usually has an image of someone, while the other side usually shows an object or a scene or symbols of different states. Heads is the one with someone's image on it; tails is the other side.
PS -- watch spelling ⇒ picture
Yes, the rules you have described for the game are correct. When you flip a coin, if it lands on heads, you would move one space/step/circle forward, and if it lands on tails, you would move two spaces/steps/circles forward.
In terms of which side of the coin represents heads and tails, typically the side of the coin with a number or a picture of a person is considered the heads side, while the opposite side is considered the tails side. However, it is important to note that different coins may have different designs, so it's always a good idea to clarify which side is being referred to as heads or tails before starting the game.
