Rules: Combination of Star Battle and Cave. Place digits into two cells in every row, column, and region of the left grid (one cell in the example). Digits cannot touch, not even diagonally.

Theme: Logical

Author/Opus: This is the 219th puzzle from our contributing puzzlemaster Grant Fikes.

Rules: Combination of Pentominous and Star Battle. Place stars into some cells so that there are two stars in each row and column; no two stars can touch, even diagonally. Then divide the rest of the grid into 16 regions each containing 5 cells. Regions with the same shape (including rotations/reflections) cannot share an edge. A cell with a letter in it must be part of the pentomino shape normally associated with that letter; an inventory of pentominoes is given below the puzzle.

Answer String: Enter the letter associated with the pentomino occupying each cell or an asterisk (*) if it is a star in the marked rows from left to right, separating the groups with a comma. Use CAPITAL LETTERS! Example: IIIII*LFF*,TTT*PP*VVV

Time Standards (highlight to view): Grandmaster = 4:45, Master = 8:15, Expert = 16:30
