HOW TO PLAY

How to play Polarity Parcel

Cycle each pair on a fixed 4×4 board through unknown, positive–negative, negative–positive, or neutral. Once every pair is explicit, check row and column pole totals and orthogonal neighbors across distinct dominoes. Solve four parcels in sequence.

Controls

  • Click or focus a domino button, then press Enter or Space to cycle its state.
  • Use Undo, Restart, Check Parcel, and Next Parcel.
  • Choose one of six interface languages.

Tips

  1. Unknown is not neutral; set every domino explicitly.
  2. Row and column clues list positive and negative targets.
  3. Only matching poles across distinct dominoes are forbidden; neutral cells count toward neither total.
