Lattice: Daily Logic Puzzles

Lattice is a calm daily set of four hand-crafted logic puzzles. A fresh grid every day at midnight.

SHIKAKU Carve the grid into rectangles, each holding exactly one number that equals its area.

ZIP Draw one continuous line that visits every cell in order, from 1 to the end.

TANGO Fill the grid with suns and moons. Balance every row and column, and never three of a kind in a row.

QUEENS Place one crown in every row, column, and colored region, with none touching.
