No Wiggle Room At All

This is a pretty nice puzzle. Nothing too complex, but I like how the logic works out on this one.

Not a big fan of this - it just doesn’t involve pipelining. The only thing there is to do is fill holes without losing moves.

Cute one - simple, but a good introduction to a theme.

Neat ordering idea, though a part of me is a little disappointed that the end doesn't have any pipelining.

No pipelining here. In addition to what patashu mentioned, look at lhlt by underling, it really helped me

I solved this without pipelining. :O
:))

With pipelining it should be faster, but I doubt anyone will do better than 142. :)
