## What is Shikaku?

Shikaku is a pure logic puzzle from Japan, also known as Rectangles or Divide by Squares. The grid holds a scattering of numbers. Your job is to cut the whole grid into rectangles so that each rectangle contains exactly one number, and that number is the rectangle's area.

No guessing, ever. Every puzzle has exactly one solution and it can always be reached by reasoning alone. There are no lives and no mistake counter: a rectangle that breaks the rules is simply refused by the board, so you are free to try things.

FEATURES:
• Campaign — 100 handmade puzzles in five collections, from 5x5 first steps to 12x12 expert boards
• Daily Challenge — one new puzzle every day, the same board for every player
• Quick Play — endless generated puzzles, five grid sizes up to 15x15, three difficulties
• A guaranteed unique solution — the solver verifies every board before you ever see it
• Hints — a nudge when you are stuck, never the whole answer
• Achievements — nine of them, earned by playing
• Statistics and streaks — stars, completion times and your daily run
• Plays entirely offline. No account required.

Available in 7 languages: English, Spanish, French, Italian, German, Japanese and Russian.

Draw your first rectangle and see how fast the grid falls into place.
