Play the puzzle on Sudokupad
I have spent the past three weeks fighting against myself to find a way to make a 16x16
Still Life
puzzle that resolves uniquely despite having digits higher than 9. After a successful construction using rules that only applied to the small digits I decided to give the diamond symbol a different effect when containing digits higher than nine.
I must admit
Leviathan
has been somewhat of an inspiration, and is probably helpful when solving this puzzle.
More puzzles using this ruleset were popularized by
Kafkapharnaum
and
Sktx.
Check out the
complete list of all the Still Life puzzles!
Rules:
Normal (hexadecimal) sudoku rules apply
Place the digits 0 to 15 in each row, column, and 4x4 box. Use the letters A to F for the digits 10 to 15 for the sudokupad completion and the solution code.
Still Life
Shade some cells green ("live cells") such that the – up to – eight cells neighboring each green cell contain exactly 2 or 3 other green cells and the neighbors of each 'unshaded' – or grey – cell ("dead cells") do not contain exactly 3 green cells
DIAMONDS
Consider a cell in the grid marked with a diamond. Call
A3 the 3x3 region centered on the diamond and
A5 the 5x5 region centered on the diamond.
Consider the sets of cells
S1 and
S2 defined as such:
S1 is given by the cells of
A3 inside the grid
S2 is given by the cells of
A5 not in
A3 and inside the grid.
in the following picture
S1 is marked red and
S2 is marked blue.
A cell in a diamond may be any number from 0 to F.
If the digit X in a diamond is between 0 and 9 (0≤X≤9), then there must be exactly X cells in
S1 that are alive, or exactly X cells in
S1 that are dead.
If the digit X in a diamond is between A and F (10≤X≤15), then there must be exactly X cells in
S2 that are alive, or exactly X cells in
S2 that are dead.
Note: the following rules completely reproduce the behaviour of the diamonds in
Leviathan, and only differ for large digits.
