Kraciak (Łamaniec)
Cut the day's grid into rectangles, each holding one number equal to its area, with colour clues for the shape.
Every day: A new shikaku grid each day (a 7x7 board on 3 October 2026), the same for every player, with earlier days in an archive. New puzzle: Midnight local time.

Kraciak is the daily shikaku puzzle on Łamaniec, a Polish puzzle site. You divide the board into rectangles so that each one contains exactly one number and covers that many cells; the colour of each number tells you whether its rectangle is a square, tall, wide or any shape.
About Kraciak (Łamaniec)
Kraciak is one of the daily games on Łamaniec, alongside Szarada, Literada, Fraziak and Mini Sudoku. It is a version of the Japanese puzzle shikaku, and the interface is in Polish.
The board is a grid with numbered cells scattered across it. You split the whole grid into rectangles: every rectangle must contain exactly one number, and its area must equal that number. Kraciak adds a colour hint to each number. A green number means the rectangle is a square, a blue one a vertical rectangle, a purple one a horizontal rectangle, and a number with a dashed red frame can take any proportions.
You draw a rectangle by dragging across the board or by tapping two opposite corners, and tap a finished rectangle to remove it. A counter shows how many cells you have covered, and a hint button helps when you are stuck. A new grid appears each day, and earlier ones are in the archive.
It suits fans of shikaku and other region-dividing puzzles; the shape colours make it a little gentler and quicker than the classic form.

Tips
- Start with numbers whose rectangle can only fit one way, such as squares near a corner.
- Large numbers next to the edge often have very few options.
