Lots in Space: Deconstructica

Not graded: we can’t read all its rules yet
  • Modular lines

The brief

The space station Deconstructica is formed of nine separate 3x3 modules, connected to each other with teal modular tether lines. Their locations are to be deduced.

Each 3x3 module must contain the digits 1-9 once each. If a cell on a modular tether lies in the vacuum of space (between modules), it contains a zero. All other space cells should be left empty. The digits 1-9 may not repeat in a row or column (but zeros can repeat).

Modular tethers: Each tether's endpoints are located somewhere within two different 3x3 modules. Any group of 3 adjacent cells along a tether must contain one digit from each of the modular groups [147], [258], and [0369].

Parity Change Lots: A digit in a red circle indicates the number of parity changes [i.e. from odd to even or vice versa] between adjacent digits along the attached tether.

German Whisper Lots: A digit in a green diamond indicates how many pairs of adjacent digits along the attached tether have a difference of 5 or more.

Adjacent Sum Lots: A digit in a blue square looks at the sums of each pair of adjacent digits along the attached tether, and indicates how many distinct sums there are.
