Hint 1 of 5:

Same as the Novice level, flip the START switch to begin.

Hint 2 of 5:

At this level, Dr.Brain's ideas are coming faster and there are a few more of
them.

Hint 3 of 5:

some colour-coded, i.e. only a blue idea can ride the blue rails.

Hint 4 of 5:

Again, don't let the ideas collide or send the wrong colour into the loading
dock.

Hint 5 of 5:

Flip the STOP switch to freeze the game.
