Theme: Logical

Rules: Variation of Fillomino rules where regions with the same shape must avoid each other instead of regions with the same size (all regions in a pentominous puzzle are pentominoes).

Specifically, divide the grid into 20 pentominoes so that no two pentominoes of the same shape (including rotations/reflections) share an edge. A cell with a letter in it must be part of the pentomino shape normally associated with that letter as given below the grid. Not all pentomino shapes need appear.

Answer String: Enter the letter associated with the pentomino occupying each cell in the two marked rows from left to right, separating the rows with a comma. Use CAPITAL LETTERS!

Theme: Trapped in A box

Rules: Either shade or add a single letter (A, B, or C) to each square so that each row and column contains exactly one A, one B, one C, and the rest shaded squares. Cells in the grid already marked with a letter can be shaded or remain unchanged.

Letters outside the grid indicate the first letter seen from that direction.

Numbers outside the grid describe the size of groups of consecutive shaded squares in that row or column in order. There must be at least one unshaded square between groups.

Or, see here.

Answer String: Enter the number of the column where the B is placed in each row, starting with the top row and proceeding to the bottom.
