Daily Futoshiki

Futoshiki, also called More or Less, is a Latin square with inequality signs. On a grid of size n you place the numbers 1 to n so that each appears once in every row and once in every column. Between some neighbouring cells sits a < or > sign, and the numbers on either side must respect it. A few cells may start with a number, but most of the work comes from the signs.

Puzzle-futoshiki.com has Easy, Normal and Hard grids from 4x4 to 9x9, a Renzoku variant, and Special Daily, Weekly and Monthly puzzles. The daily is one dated grid for every player; the puzzles of 2 and 21 October 2026 were 11 by 11, and on grids bigger than 9 the site uses letters, so A follows 9 and B follows A. Pencil notes, highlighting of the current row and column, and automatic removal of notes are among the settings. The site shows ads; patrons, from 1 dollar a month, lose the ads and can go back through the last 30 dailies, 10 weeklies and 5 monthlies. The site's screens come in English and fourteen other languages, and a Hall of Fame lists the fastest solvers.

Futoshiki suits sudoku players who want a different source of clues: there are no boxes, and chains of signs do much of the work. The larger daily grids are a long solve, so it fits a weekend or a quiet evening.
