## What is Art of Sudoku · Lightkeeper?

Art of Sudoku invites you to open a glass-lit museum of puzzles – a tranquil space where logic and creativity flow into one another.

Play the glasslight classic on the canvas of logic and discover the art within numbers.

Dive into four hand-curated collections, where every puzzle becomes a work of art – uniting emotion, thought, and sensation in a silent stream of poetry.

Glasslit Hall – icons from the great museums of the world, from the Belvedere in Vienna to The Met in New York. Featuring Gustav Klimt, Egon Schiele, Amedeo Modigliani, and Robert Delaunay.

Vivid Shine – a journey through the vivid colors of modernism, with paintings by Henri Matisse, Edvard Munch, Franz Marc, Paul Gauguin, and Vincent van Gogh.

Her Brilliance – an hommage to creators such as Paula Modersohn-Becker, Marianne von Werefkin, and Helene Schjerfbeck – echoes of warmth, empathy, and strength.

Pure Refraction – from Alexej von Jawlensky through Wassily Kandinsky to Paul Klee – where form is perfection.

Play lightfully.
