How Numrist works

Two puzzles in one grid

It's Sudoku first. Every row, column, and box holds each digit exactly once.

There are two kinds of line. Heavy black ones are the Sudoku boxes. Thin teal dashes set inside the squares mark cages — they never sit on the black grid, so the two never get mixed up.

Those two cells sit in one cage: 3 + 4 = 7, target met, green. Only a cage's top-left cell carries the label, so a blank cell always belongs to whichever outline encloses it. Tap any cell and its cage lights up gold.

The twist: two cages that touch edge-to-edge never share the same operation. Every grid is built that way.

A cage turns green when its digits hit the target, red when it's full but wrong — or when a digit repeats in a row, column, or box.

Signed in, a solve scores points: higher tiers are worth far more, finishing faster than typical scores more, and each hint used scores less. Your best score per tier shows on Rankings and in My Board.
