Read regions first, then expose the most constrained pairs.
Read each rule
A region may require a total, a minimum, a maximum, matching values, or different values.
Follow both tile halves
A decision affects two cells because every lettered domino is a fixed pair.
Reveal only when stuck
Use the next-pair control as a graduated hint or reveal the completed practice board.
Pips Solver and Domino Logic Trainer FAQ
Is this today's official NYT Pips puzzle?
No. These are original practice boards that explain the same broad style of domino constraints without reproducing a current copyrighted puzzle.
What does the not-equal symbol mean?
The values inside that colored region must not all be identical.
Does clicking one cell reveal both halves?
Yes. A Pips-style tile is a pair, so both linked cells are shown together.
