Sample puzzles
Why these puzzles?
Samurai (Gattai-5) joins five classic grids: the four corner grids share their inner 3x3 box with the center grid. The shared boxes couple everything, so progress in one grid unlocks the others — a longer, more strategic solve than any single 9x9.

Solving tips
Start with the center grid: its four shared boxes receive information from every corner. When a grid stalls, switch to a neighbour — a digit placed in a shared box works in both grids at once.
