Place the digits 1-7 exactly once in every row and column. Place 8 polyominoes (an L pentomino, an N pentomino, a P pentomino, a U pentomino, a V pentomino, a Y pentomino, a Z pentomino and a 2x3 rectangle) exactly once in such a way that only the cells with grey text in them are not covered by one of the shapes (ie the "8", the "Jun" and 6 cells with "X" in them), so the grid spells out 8 June (Simon's Birthday). The polyominoes can be reflected and rotated as required. Each cage is part of a polyomino and no polyomino can have more than one cage. This cage can be anywhere in the polyomino. The small number in the top left of the cage gives the sum of the digits of that polyomino and digits can't repeat within a polyomino. The digits along the pointed diagonal sum to 45. There are some cells with oddballs in the puzzle, which have odd digits in it. These are put in, because Simon is a bit of an oddball, in the most positive way: an eccentric and exceptional character.
