This App is based on the old 1960s wooden craft game. My dad made
one of these – hours of fun ( although this was before the age of computers, video
games, and Apps). While it is a fairly simple game, it can be quite challenging.
The object of this game is to move a marble down the slalom course by tilting the
interior boards allowing the marble roll along until it gets to the end of the board and
falls to the next board. But be careful, cause if the marble is rolling to fast it roll of the
end of the board all the way to the bottom. The original wooden game had two levers
on each side to tilt the inside boards, while the app uses two sliders. This app uses the
formulas for gravity and motion to control how the marble move (simulates the actual
movement pretty well).
