Best DOS puzzle games

What do you think were the best PC Dos puzzle games?

For me, it would be:

Lemmings
Incredible Machine

I'll have to go with Lemmings, had lots of fun playing that and solving the puzzles there.

I did play Incredible Machine as well, good game but not as fun as lemmings in my opinion.

Lemmings is a classic!

I also liked a (less known) DOS game called "Loader Larry" which had some pretty cool puzzles
