SLATEVEIL

Every panel wants something. One wants its pips all equal, one wants them all different, one wants them to add up. Set every stone so every panel is satisfied — plenty of walls will do it.

Then there is the mortar. Wherever two stones meet uneven, the seam costs the difference. The wall that fits is rarely the wall that's tight.

HOW IT WORKS

Panels carry marks

A panel marked = wants every pip inside it the same. wants them all different. A number wants them to add up to it.

Seams cost mortar

Two stones meeting five-against-one costs four. Three-against-three costs nothing. Only different stones owe — the two halves of one stone are a single piece.

Par is proved, not guessed

A solver cracked every shipped wall before it left the workshop. Hit par and you have found the tightest wall that exists.

One Daily, everyone

The same wall for every player, scored on mortar against par — and it counts whether or not you finish it. A streak a bad day can break is a streak nobody keeps.
