UK PM Puzzle

Score points by matching pairs of UK Prime Ministers with their dates in office while learning the British Prime Ministers History.

There were 75 British Prime Ministers elected up to date, some more than onces, altogether 52 men and 1 woman, so we have split them up into 7 groups in numerical order of their premiership.

You will see a grid of cards, tap two cards to find a match. The matching pair will then disappear.
Continue until all pairs have disappeared
