Latin Square: Fill the full grid so that each column contains the digits 1 through 9 without repetition.

Squishdoku: The central 7x7 square contains the digits 1 through 9 such that no digit repeats in any row, column or 3x3 box as marked out by the dotted lines.

Green Dots: A green dot separates two digits which differ by 5 or more.

Skyscrapers: The outermost cell in a row or column marked with a skyscraper is a skyscraper clue for the central 7x7 grid. It counts how many of the seven cells in that row or column have no larger cell than themselves in between them and the skyscraper clue.

Full Rank: The outermost cell in a row or column marked with a ranking symbol is a full rank clue for the central 7x7 grid. If the 28 seven-digit numbers starting from each outside edge of the 7x7 grid (seven from the left side, seven from the top and so on) are ranked in ascending order from 1 to 28, the full-rank clue tells you where in this order that seven-digit number sits.
