Logic Masters Deutschland e.V.

This is my response to Scojo's setting prompt this week, where we were asked to make a puzzle in our own style and then impersonate the style of another setter with a second puzzle the following week.

I want to give due credit to the setter who inspired this intro: my impostor (spoiler alert). Seriously, though, his puzzle in my style is stunningly clever and witty, and the idea that I could've set it is an enormously humbling compliment.

Fully Charged was actually the second draft of this idea. The first is far too similar a puzzle in terms of the main deductions required to warrant its own LMD page, and I think Fully Charged is the smoother of the two, but some of the disambiguations were a little more interesting in the other puzzle, I'd say.

Squischröquadri (first draft of Fully Charged)



Normal Squischröquadri rules apply: The grid contains four 3x3 boxes, which overlap at the dashed lines. An S-cell is a cell that contains two digits, and its value is the sum of its digits. Place one or two digits from 0-9 into every cell such that:
- No digit may repeat in a row, column or box;
- No digit may appear in more than one S-cell;
- No row, column or box may contain more than one S-cell.

Local constraints: Values in a cage sum to the given total; values on a yellow arrow sum to the value in the arrow's orb; an inequality sign points to a lower value.
