Lots of last minute flurry in the S household! I needed to come up with a Christmas-themed puzzle in a hurry. Fortunately, my ever-reliable spouse handed me a list labelled "last minute" and I was able to construct the following puzzle.
Divide into groups:-
ANDERLECHT | BATMAN | BOAT | BRING | BROWNING | COUCH |
DANVERS | DOWN | DREAMS | HORSEHAIR | HOT | IMPERATOR |
ISTANBUL | LINGER | NANTES | NOW | POLYFILL | RWDM |
SEED | TRAIN | UNION | US | VAN | ZOMBIE |
Do you think that they'll be pleased with this?
