Hint #1: 16-Across and 24-Down loosely describe the mechanism... the game mentioned in 60-Across is worth looking up... and beware of falling into 8-Down
Hint #2: Study all the clues carefully
Hint #3: Note that there are lots of repeated words... spectrum, gambling, curry... this can't be a coincidence can it?
Hint#4: The last word of a clue would lead you to the first word of another clue - example: 1A Ingredient in a bhindi masala curry leads you to 26-Down curry favor... then the new last word favor will lead you to a new clue that starts with that word and so on
Hint 5: You will end up with a 21-word chain... take the first letters of the entries in this chain... it's up to you to determine where the chain starts
