Slateveil: Domino Puzzle

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 — that is the puzzle, and plenty of walls will do it. Then there is the mortar. Wherever two stones meet uneven, the seam costs. A five against a one costs four. A three against a three costs nothing at all. So the wall that satisfies every panel is rarely the wall that costs least, and the whole game is finding the one that does both. Every wall ships with a par that was PROVED, not guessed — a solver cracked it before the board ever left the workshop. Hit par and you have found the tightest wall that exists. Miss it and you will see by exactly how much. • 150 walls across six courses, from Footing to Capstone • One Daily, the same wall for everyone, with a streak that survives a bad day • Plumb names a stone on an optimal wall.…
