Rules:
Sudoku: Fill every row, column and 3x3 box with the digits 1-9.
Sandwich: A clue outside the grid gives the sum of the digits sandwiched between the 1 and the 9 in the corresponding row or column.
Lockout Lines: Digits on a line must fall 'outside' the range of their diamond shaped endpoints (eg. endpoints 1 and 8 only allow 9 on the line connecting them). Each endpoint value must differ by at least 4 from other directly connected endpoints. Digits on a line may repeat if allowed by other rules.
Have fun solving!

Not too hard but very, very fun! The sandwich clues were used beautifully.
