Buttery Biscuit Base
(Published on 24. October 2021, 20:17 by fjam)
- Normal Sudoku rules apply.
- Clues outside the grid give the sum of the digits sandwiched between the 1 and 9 in their respective row/column.
- The digit placed next to the 1 inside a sandwich is the butter. Every sandwich clue is given in the numerical base of the butter.
Normally numbers are written in base 10, for example:
3576 = 3×103 + 5×102 + 7×101 + 6×100
In a different base, any number is expressed similarly. Using 61 as an example in base 3, 5 and 7:
61 = 54 + 6 + 1 = 2×33 + 0×32 + 2×31 + 1×30 = 2021 in base 3
61 = 50 + 10 + 1 = 2×52 + 2×51 + 1×50 = 221 in base 5
61 = 49 + 7 + 5 = 1×72 + 1×71 + 5×70 = 115 in base 7

This is a fantastic puzzle! Loved every second of it, one of those puzzles I wish I could play for the first time again.

Easy to get lost along the way if you're not careful, but the logic is there if you can spot it. Solid puzzle
