Tough one........I worked out two of the groups but not the correct four for each group in time but I would never have got the canopy one.....good work

nice one, got the canopy one, but gave the answer as types of tent

Badly designed. The groups should be more specific as Tuvalu is a polynesian island so it shouldn't be a case of clicking every combo until you find whatever combination the creator deemed, without any wit or reason so it can be rationally determined.

Duh! Jack, that's the whole point of red herrings!

Well said Christobal!

Christobal & OSSIEP9 - yes and no. Obviously, most good groups have red herrings. But I think that a perfect grid gives hints as to which combination is most likely - so if you are smart, you don't have to do as much random clicking. For example, if the other islands had been, say, Caribbean, and you knew that, then your knowledge would save you time. This is, after all, meant to be a test of general knowledge too - not just the ability to spot connections.

I thought that one was alright, actually. I did get the First group... first, so that knocked out enough red herrings to narrow the rest down.
