After all three yellow\nLEDs have flashed, the red LED lights up indicating the start of the game\nyour task is to press the buttons corresponding to each LED in order to\nget the value that will be displayed. There is a catch however! Each button\ncan only be pressed once as subsequent presses have no effect on the value.\nThe game can be solved with a maximum number of 3 unique button pushes\nand as little as one button push.\nGood luck!\n");
