Shade some empty cells so that no two shaded cells are orthogonally adjacent and the remaining unshaded cells form one orthogonally connected area. No complete loop of cells may be unshaded (including 2x2s). An arrow indicates the only direction in which one could begin a path to the star without going through a shaded cell or backtracking.

The Chains That Bind Us

Pairdoku Playground
by myShoggoth
Normal sudoku rules apply. Pairdoku - there are two different grids with the same solution, but not enough information to solve alone. Two solvers work together by sharing information on what digits are constrained, but not what the constraints are nor describing their grid. The grids are blurred above so too much information is not given out ahead of the solve. Each grid has information about its own constraints. These grids are generally domino constraints and killer cages.
