Use arrow keys to control flagman and copy the pattern flagman shows you after he says "Go!". When a foot or flag is already out, it will go back in if it's key is pressed, and vice versa. Click the "Click when done" button to lock in your movement and see if you copied the pattern correctly. Basically, this game is like Simon Says. Have Fun!
Thanks to the Mr. Game and Watch Flagman game for inspiration. Fun fact! This was the second game released in the Mr. Game and Watch series!
