Over: more candidates allowed than the row length
Algebraic: cage totals do not have to be sums: note some of us were creating these before KenKen hit the English speaking streets
Killer: a debased way of saying samunamupure (noting of course that sudoku is a debased way of saying number place)
This is a basic Ken-Ken 6*6 however instead of the candidates being 1 to 6 they are a set of six numbers from 0 to 9 and part of the puzzle is, of course, to derive which six.
OAK 1
This is easy-peasy to get you going.
The cages without a sign are sum cages, however they can be treated as unknown-operator and the puzzle is still straightforward.
OAK 2
This one is harder. Note I allow a certain element of T&E in eliminating candidates.
The cages without a sign are sum cages.
If you wish to work on a solver use the first six rows and columns of a 12*12 Latin square.
