Using tilt and steadiness, roll the 7 Marbles onto each of the 7 white markers.
When a marble is close enough to a marker, the marker will have a slight pull on it and keep it in place. Be careful though, the pull on the marker is weak so be mindful the marble could sling off as you try to position the remaining marbles on the other markers.
When all 7 marbles are positioned on each of the 7 markers, you win!
