Normal 6x6 rules apply to each grid. Place the digits 1-6 into each cell of each grid so that each digit appears once in each row/column/box. 2) Normal rules for white/black dots, XVs, arrows, renban, German Whispers, and killer cages also apply. There are no negative constraints of any kind Note that German Whispers in this puzzle require a difference of at least 5, like in a 9x9 Grid. 3) Additionally, in each grid, one cell in every row, column, and box contains a doubler. For purposes of clues, a cell with a doubler counts for twice its value. 4) No two of these six puzzles contain doublers in the same cell. Some examples with doublers: a 2 cell 8 killer cage could contain a 4 and a 2 with a doubler or a renban could contain a 3, a 3 with a doubler, a 4 and a 5.
