The Doppit Almanac · No. 21
Summit, a daily Calcudoku
Fill 1 to N so every cage hits its number
What it is
Summit is Doppit's daily Calcudoku, the caged arithmetic puzzle. It climbs at No. 21. Every cell takes a number from 1 to N, the width of the grid, and every row and every column must hold each number exactly once. The diagonals answer to nobody.
Over the top lie outlined cages, each with a small demand in its corner. The numbers inside must hit that figure by the printed operation. The grid does the ordering; the cages do the arguing.
How it plays
The route card reads as follows.
- Each row and each column holds every number from 1 to N once.
- A + cage adds its numbers to the target; a × cage multiplies them.
- Minus and division sit on two-cell cages only: bigger minus smaller, or bigger divided by smaller.
- A cage may repeat a number when its cells share no row or column.
- Easy boards open with a few numbers locked in. Pick a chip, tap to place, let Notes pencil your candidates; clashes glow red.
The difficulties
Three ascents are roped daily. Easy is a four-wide grid of plus and minus cages, summited in thirty seconds to a minute. Medium is four wide as well and takes one to three minutes of sums and differences. Hard steps up to five wide and puts times and divide in the cages, three to six minutes with thin air the whole way. Expert is six wide with the same four operations, thirty-six cells to fill. A new board is fixed every day, and there is no guide fee. Expert is not fixed daily; it is rigged and left for practice.
