Hints for all three boards are below, from lightest nudge to stronger guidance. The available records do not show verified tile-by-tile placements, so this page does not invent a complete answer.
How to read these Pips hints
Try the hint for your board before reading further. Each clue identifies a useful starting region, not a confirmed sequence of domino placements.
| Board | Squares | Dominoes | Regions | Opening focus |
|---|---|---|---|---|
| Easy | 8 | 4 | 3 | One-square region marked = 2 |
| Medium | 14 | 7 | 6 | Three-square region marked = 1 |
| Hard | Not stated in the available archive summary | Not stated in the available archive summary | Not stated in the available archive summary | Four-square region marked = 13 |
Easy board hint
Start with the one-square = 2 region
That square must contain a domino half showing exactly two pips. Use that restriction to narrow which tile could cover it, then check whether the tile’s other half can fit the neighboring area. The easy board has eight squares, four dominoes and three regions; two regions have exact-sum clues and one uses a less-than clue.
Medium board hint
Work from the three-square = 1 region
A total of one across three squares strongly limits the values that can lie in the region. Consider low-valued halves first, while remembering that a domino crossing the region boundary contributes only the half inside it. Use the remaining tile inventory and board shape to rule out combinations that cannot complete the covering.

Hard board hint
Track the four-square = 13 region
Add the values on the four squares in this region, including only the relevant half of any domino that crosses its boundary. Once you have candidate combinations totaling 13, test them against the available tiles and the geometry of the neighboring spaces. This is a starting constraint, not a verified full arrangement.
How Pips works
Cover every board square with exactly one half of a domino, using each displayed domino exactly once. Then satisfy the rule shown for each connected region. Depending on the clue, a region may require equal values, distinct values, an exact total, or a total above or below a threshold. The December 16 archive describes the tiles as coming from a standard double-six set.

A practical solving method
- Find the tightest constraint. A single-square clue or a small exact total usually offers a useful starting point.
- List feasible pip values. For a total clue, enumerate values that can fit the region’s squares before committing to tile placements.
- Account for boundaries. When a domino spans two regions, each region counts the pip value on its own square.
- Check the tile inventory. Every domino is used once; a candidate that consumes a tile needed elsewhere cannot work.
- Verify the geometry. Even a numerically valid set of values must allow every square to be covered without overlap or gaps.
A physical double-six domino set is optional for practicing placements; it is not required to play the digital puzzle.
