Normal Sudoku rules apply: Fill the grid with the digits 1-9 so that each digit appears once in every row, column, and 3x3 region.
Tesbus Cages: A cage cannot include every digit from another cage - in other words, no cage is a subset of any other. Digits in a cage do not repeat.
Quadruples: Each digit in a circle appears in one of the four cells the circle touches.
