You got the Goblin's first 2 rules wrong Stix, so you get the Gong!

OK, My turn:
Rule 1 - The horse finished fifth or worse at its last start.
Rule 2 - The horse was placed at its 3 starts before that.
Rule 3 - must be a racing against own sex [or better].
Rule 4 - must be 3rd up. [2.3.X. 2.7 as a formline example]
Rule 5 - must have a D, T, or C next to it's name
Rule 6 - must not be going up or down more than 2kgs.

Piece of cake!
