Scratch

Can somebody please help me -- Develop a program that simulates the game of Two-Up. In this game, a player enters either “Heads” or “Tails” before the program simulates the tossing of two coins. If the player enters “Heads” and both coins come up Heads, then the program announces that the player won and 10 points are added to a score that is displayed. Similarly, if the player enters “Tails” and both coins come up Tails then 10 points are added to their score. The player loses 10 points if they guess incorrectly or if one coin displays “Heads” and the other coin displays “Tails”.-- Im new to scratch and i wasnt sure on how to do this.. please help!

thanks guyss
