LOCO Sudoku changes both the layout and the rules. A single puzzle can combine Jigsaw, Diagonal, Killer, Outside, Hyper, Frame, and other Sudoku variants, with each sub-grid following its own constraint system.
For advanced variant solvers who are comfortable switching rules and using the overlaps to carry deductions between very different Sudoku types.
These puzzles deliberately mix Sudoku rule systems. Different grids or sections may use different constraints, while shared cells connect the rules into a single puzzle. Success depends on identifying which rule applies where and carrying deductions across the overlaps.

The physical edition contains 101 puzzles across 116 pages in a 8 x 10 inches trim size. That format is part of the buying decision: compare it with the neighboring DJAPE volumes by quantity, difficulty, and working space rather than by title alone.
