Logic Masters Deutschland e.V.

Set for a Scojo Setting Saturday prompt challenge given by gdc about Mad Fold-in puzzles. Thanks to all that tested!

If you want a version with the folded region next to the full grid to make it easier to visualize, you can get that here but it is not recommended unless you are struggling as part of the fun is visualizing the folded part from the unfolded.

• Fillomino:

  • Divide the grid into regions, such that no two orthogonally adjacent regions have the same size.
  • Write the size of its region into each cell as that cell's value.

• Mad Fold-in:

  • If the cells between the dashed columns are removed, all regions and clues fold into valid regions and clues in the resulting 4x9 grid.

All feedback (positive or critical) appreciated!
