A clear five-minute ritual

How Daily Lattice works

  1. 1

    Read the equations

    Each row and crossing is a complete arithmetic statement.

  2. 2

    Place every number once

    Drag the available tiles into the cells where every equation can be true.

  3. 3

    Share the result, never the answer

    Your spoiler-free result card shows time, streak, stars, and the board shape.

Fair by construction

A daily puzzle that never asks you to guess

Every Daily Lattice is checked by the same puzzle engine that verifies your solution. There is exactly one answer, and every move can be reasoned from the board.
