padding can be added to move objects away from the edge of the element container.

main.py

import kivy
kivy.require('1.9.0')

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout

class Sample(BoxLayout):
    pass

class SampleApp(App):
    def build(self):
        # return the boxlayout class defined above
        return Sample()

if __name__ == '__main__':
    SampleApp().run()

<Sample>:
    orientation: 'vertical'
    button_font_size: '30sp'
    padding: root.width * 0.02, root.height * 0.02 #<=== 2% padding
    Label:
        text: 'Guess N sampling game!'
        size_hint: 1, None
        height: self.texture_size[1]
        font_size: '45sp'
    Label:
        text: 'Game info to go here...'
        size_hint: 1, 1
    TextInput:
        text: 'Guess N...'
        padding: root.width *0.05, root.height * 0.05 # <=== 5% padding
    BoxLayout:
        orientation: 'horizontal'
        size_hint: 1, None
        Button:
            text: 'Clear'
            size_hint: None, None
            font_size: root.button_font_size
        Button:
            text: 'Guess!'
            size_hint: 1, None
            font_size: root.button_font_size
        Button:
            text: 'Quit'
            size_hint: None, None
            font_size: root.button_font_size

Output
Note the addition of spacing around the edge of the boxlayout. Also notice that this didn't add spacing between buttons or other elements.
