The games

All the games in one place

Kakuro, Futoshiki, Skyscrapers, and Calcudoku: four number puzzles, four pages, four sets of best times. Each has its own illustrated rules and its own daily challenge, and each runs entirely in your browser — no account, no download, no ads.

  • Kakuro tile: the game's motif in wood and greens.
    Cross-sums

    Kakuro

    Fill the white cells with 1 to 9 so that each block reaches its sum, never repeating a digit within the same block. A few cells are already filled in.

    Play

  • Futoshiki tile: the game's motif in wood and greens.
    Grid and inequalities

    Futoshiki

    Place 1 to N once per row and column while respecting the chevrons: the point of the sign always aims at the smaller number.

    Play

  • Skyscrapers tile: the game's motif in wood and greens.
    Heights and lines of sight

    Skyscrapers

    Place towers of different heights so that each edge sees the right number of skyscrapers, with taller ones hiding shorter ones.

    Play

  • Calcudoku tile: the game's motif in wood and greens.
    Latin square and arithmetic

    Calcudoku

    Fill the grid with no repeats in any row or column, and make each cage match its result and its operation.

    Play

What all four share

The same rules for every game

  • Every grid is generated and then run through a solver: one solution, and only one.
  • One daily challenge per game, drawn from the date, the same for everyone until midnight.
  • Mouse, touchscreen, and keyboard all work, and nothing depends on color alone.
  • Best times stay in this browser, and only if you accepted the “Preferences” category.
