Puzzling InvalidD

 To prove that I can make 3 posts in one day. (I heard that this one was apparently kinda hard?) Online Play Link Nurikabe rule (from Nikoli ): Fill in the cells using the following rules. You cannot fill in cells containing numbers. A number tells the number of continuous white cells. Each area of white cells contains only one number in it and they are separated by black cells. The black cells are linked to be a continuous wall. Black cells cannot form a 2×2 square or larger.

To prove that I can indeed count to 2. Online Play Link  Shakashaka rule (from  Nikoli ): Place black triangles in the grid under the following rules. There are four kinds of black triangles you can put in the squares: You cannot place black triangles in the black squares. The parts of the grid that remain white (uncovered by black triangles) always form a rectangle or a square. The numbers indicate how many black triangles are around it, vertically and horizontally.

To prove that this place isn't forgotten. Online Play Link Masyu rule (From Nikoli ): Make a single loop with lines passing through the centers of cells, horizontally or vertically. The loop never crosses itself, branches off, or goes through the same cell twice. Lines must pass through all cells with black or white circles. Lines passing through white circles must pass straight through its cell, and make a right-angled turn in at least one of the cells next to the white circle. Lines passing through black circles must make a right-angled turn in its cell, then it must go straight through the next cell (till the middle of the second cell) on both sides.
