Weekly themes and holiday boxes

Published October 16, 2026.

A box is not just a puzzle: it is also an object with a look. The decorations change every week, and take on seasonal colours on the big holidays.

One theme per week

Each week has its theme, in rotation: Marine, Cartographer and Bookbinding. The theme changes the decoration of each face, not the difficulty: the same mechanisms hide behind a decoration of ocean, old map or bookbinding workshop. The decoration is never a pattern to count: only the symbols of a clue count.

Halloween and Christmas

Halloween takes up the period from 26 October to 1 November each year, on fixed dates: it builds towards the 31st whatever the day of the week. Christmas runs from 1 to 25 December. During a holiday, the holiday's theme replaces the week's theme.

24 December is a big box, at maximum difficulty. When the lid opens and on the end screen, a seasonal treasure awaits you.

Adapted symbols

Holiday boxes avoid certain symbols and patterns so that the decoration does not muddle the reading of clues: for example, no discs during holidays. Christmas only uses six symbols and two patterns, which does not stop the boxes from being varied.

For the fun of playing

The « For fun » section offers extra boxes, easy, medium or hard, which also pick up the current holiday's theme. They are played freely, with no effect on your streak.

Why themes?

A theme gives the week an identity: you recognise a Marine, Cartographer or Bookbinding box at first glance, by its decoration. This makes each week recognisable without changing the substance of the game: the rules, the mechanisms and the difficulty remain those of the day of the week.

A theme only changes the look: if one week's box seems harder than another, it is because of its day of the week, never its decoration. Decorations hide no clues either: what matters to solve the box is always drawn on the plates, the legends and the mechanisms themselves. Archive boxes keep the theme of their original week: you can thus find the atmosphere of a past box by replaying it.
