Puzzle 300: Quattro Stagioni

General Rule: Shade some cells to form a single contiguous shape. The shape doesn't form any 2x2 squares anywhere, even between boundaries. The coloured squares represent windows, the pattern of shaded and unshaded cells in the solid window must be the inverse of the pattern of shaded and unshaded cells in the dashed window of the same colour. The orientation of which stays the same.

Top Left: Nurikabe Pentominoes

1. Each lettered cell is an island cell, the letter in it indicates the pentomino it is part of.
2. Each island contains exactly one lettered cell. All unshaded cells in the top-left are part of a pentomino.
3. Pentominos must be contained completely within the top-left area and don't connect to unshaded cells in other areas.

Top Right: Nanro Signpost

1. Each area must contain at least one shaded cell.
2. Numbers in some cells count the shaded cells in that area, however that cell may not be shaded upon completion.
3. Where two shaded cells connect across a boundary between areas, the number of shaded cells in those areas must be different.

Bottom Left: Large-Squares Tapa

1. Numbers on some cells indicate the number of consecutive shaded cells around that cell, if there is more than one number then there must be at least one unshaded cell between the shaded regions, "?" is wild and can stand for any number from 1 up to the number of surrounding cells.
2. Where clues are in large areas, they relate to all cells surrounding that area.
3. Cells with numbers can never be shaded.

Bottom Right: Easy as LITS

1. No two of the same tetrominos, including rotations / reflections are allowed to touch.
2. Letters outside the grid indicate the first tetromino encountered in the corresponding direction.
