I expected that Up and Down 1 would effectively have only one solution. I left Up and Down 2 a little more open-ended with the gaps on the sides. Nice to see the different approaches there. Lets see how you do when you have 4 less spaces to work with.
And krisper, welcome to the forum ! It's always good to see some new people. Don't worry about the quality of your solutions. The more solutions you do, the more you get the hang of it. These Small 'n Difficult puzzles can be real brain-wreckers sometimes, so it's an achievement to find a solution at all !
