## What is Shikaku Puzzle?

Play Shikaku with 1,150 rectangle puzzles across five difficulty levels. Start with a 4x4 grid, work up to 18x18, and solve offline at your own pace.

Shikaku is a Japanese number puzzle: draw rectangles so each one contains exactly one number and covers that many cells. Fill the whole grid without gaps or overlaps.

YOUR NEXT PUZZLE CHALLENGE
- 1,150 levels: Baby (50), Easy (100), Medium (200), Hard (300) and Expert (500)
- Grids from 4x4 to 18x18 for short breaks and longer solving sessions
- Targeted hints: choose a numbered cell to reveal its rectangle
- Undo moves, reset a board and track your solve time
- Daily and weekly missions, achievements and streaks
- Light and dark themes, with support for 46 languages

HOW TO PLAY
1. Pick a numbered cell.
2. Drag to draw a rectangle containing it.
3. Make the rectangle cover exactly as many cells as the number.
4. Cover the whole grid, with one number in each rectangle.

FOR NUMBER PUZZLE PLAYERS
Enjoy Sudoku, Nonogram or Kakuro? Try a different kind of deduction with Shikaku. The rules are short; larger grids give you more possibilities to work through.

OFFLINE PLAY AND PROGRESS
Play the puzzles without an internet connection. Optional Game Center cloud save lets you carry your progress between iPhone and iPad; syncing requires a connection.

ADS AND OPTIONAL PURCHASE
Recto is free to play. Ads may appear between levels, never while you are solving a board. Watch an optional rewarded ad to earn extra hints. An optional one-time purchase removes between-level ads. No subscription.
