What are these types of questions/quizzes called?

Okay so the theme is Battle of flowers and you have to work out answers which would be a type of flower from the given clues. e.g. winter avalanche=snowdrop, reynard's mittens=foxgloves, will i be remembered=forget-me-not, needs no gilding=lily, von trapp family flower=eldeweiss, foppish head of the jungle=dandelion, and it's perfect to feed a baby pooh bear=honeysuckle. so what are these types of questions/quizzes? because i really want to know and i have to do an activity in a few weeks and i thought this would be really good?! please help! :)
