Flex entries are safer as you can still win even if up to three of your player selections are incorrect (this only applies to entries with more than 9 picks).
A 6-player selection with a Flex entry will give you 20X if you get all right, 2X if you get one wrong, and 0.4X of your money back if two picks are incorrect.
