Don't let ED the Evil Droyd win all the marbles...

Since "ED" the Evil Droyd is very evil, you will always go first.  The 16 gates and 2 elevators steer the marble towards one of the 6 goals.  For each marble you get to change one gate position before the marble drops.  First player to the selected number of marbles wins.  A black hole will absorb the marble and cause a loss of turn.

Black Holes:

Never = No black holes

Before = Reveal location before first marble

After =  Reveal location after first marble

Random = Change location every marble

Hints: Ed may be evil, but he doesn't know about the black holes...
