Spoilt means ruined, or given so much that the character suffers. A spoilt child, spoilt for choice, the food was spoilt.
Britain uses spoilt and America spoiled, and both are correct for the same word. Spoilt for choice is a fixed phrase and means having so many options that choosing is hard, which is a complaint nobody takes seriously.
