I don't usually bother with puzzles with as many 1s but I wanted to see what it was! Top and bottom rows are irresistibly obvious leaving no challenge.

I like 1s. They are salt and pepper of hanjies.

Completely logical - and yes, I do remember these !

Very nice puzzle! Thank you!

Sadly, I have to use one of these at work. My boss is technophobic.

Yes - I remember - but it's not an animal ;-)

Fully logical despite all the 1's. Well done!

Thanks.
