Good

Not 'very easy' like the name suggests. Should be under 'fiendish'.

too hard to be fun

Really clever but stupidly hard.

I wouldn't call it particularly clever to use two sets of rivers.

requires specific geographical knowledge as opposed to reasoning power. If the knowledge is in place then it is very straightforward, with no crossovers or herrings. If it is not, then there is little chance you can think your way through the puzzle to solve it. That is why it is not enjoyable.

Agree. This was.... not great.

The bass group sticks out like a sore thumb - I can't see how it was intended to interact with the rest of the grid. thereafter it's a test of world geography with the only chance of insight being guessing that there are 8 rivers rather than 5 or 6. Crossovers were thin on the ground.

Better rivers might have been those that could be easily mistaken for something else - eg Amazon, Po, Darling, Colorado, Yellow ( though they have been done before... ). yes Amur is also a forest or a tiger, but a) as such it was all on its lonesome and b) Theyre all geography based.

Pretty poor tbh, as mentioned, too much specific knowledge required, no crossovers, and using the same grouping twice albeit slightly changed is pretty lazy

Excellently summed up by haywood

What a stupid, irritating grid - unless you're a Hindu geographer it's awful.
