4 days, 4 puzzles

Hi guys,
I figured I have some spare keys/gifts that I'd like to give away. I'll post here 4 puzzles, the rules are as usual, no sharing, hints etc. I'll tell you the name of the games though.

If you know this kind of puzzle it should be a walk in the park, the only hint I'll give you is that the second character is a number.

Solution: the rules of this game are simple: number represents the number of surrounding lines, the solution must bi one connected line. Unfortunately I made a little mistake but the puzzle was still solvable, you have the solution here, orange line shows you alternate solution, I think we can agree that you can recognize A with both solutions.

Another similar one. Have fun solving it.

Solution: you should fill the grid with coloring the squares, how you color them is determined by the numbers, 2-3 would mean that you need to color two squares together, have at least one free and than color three together, solution should look like this: solution

This time it's just a simple matter of connect the dots. With a twist.

Solution: as I said, it was connect the dots but instead of connection numbers like in primary school you had to connect the numbers in Fibonacci series, the hint was in two 1s. Anyway, here's the solution

(2,0)(0,4) (2,0)(4,4)
(5,0)(5,3) (5,0)(6,1) (6,1)(5,2)
(9,0)(7,4) (9,0)(11,4)
(12,0)(12,4) (12,0)(15,0) (12,2)(14,2) (12,4)(15,4)
(16,0)(16,4) (16,0)(18,0)
Solution is as always a 5 char giveaway ID.

I'll bump the thread when I add a new puzzle.
