## What is Shikaku?

Master the Geometry of Logic.

Step into the world of Shikaku (also known as Rectangles), a classic Japanese logic puzzle reimagined for the modern era. Shikaku is a minimalist experience designed for those who find beauty in structure and peace in problem-solving.

THE GOAL Divide the grid into rectangular and square pieces such that each piece contains exactly one number. That number must represent the total area (the number of cells) of that rectangle. It’s simple to learn, but mastery requires a deep understanding of logical geometry.

WHY PLAY SHIKAKU? • Handcrafted Minimalism: A clean, distraction-free interface that lets you focus entirely on the puzzle at hand. • Daily Chapters: Every day brings a new "Chapter" with three stages of escalating difficulty. Start your morning with a light challenge and end your day with a masterclass in logic. • Infinite Endless Mode: Never run out of puzzles. Generate grids of various sizes—from quick 4x4 warm-ups to daunting large-scale grids. • Personalize Your Experience: Express yourself with over 16 vibrant themes, including Tokyo Neon, Sakura, Botanical, and Midnight. • Mastery XP System: Prove your skill. Turn off assistive features to earn 1.5x XP and climb the ranks of logic masters. • Zero Distractions: No ads. No interruptions. Just you and the grid.

Whether you’re a Sudoku veteran or a casual puzzle lover, Shikaku offers a meditative yet mentally stimulating escape.

Handcrafted with pride by De Groot Studio.

### 4/5 — great game but

*2026-07-22, version 1.1*

amazing game with no ads and fun way to kill time however there’s bugs with the master levels that include the question marks. when you fill it out sometimes it won’t say that you solved it one of them is level 144x

### 3/5 — Fun, but can’t turn sound off

*2026-07-06, version 1.1*

I really like this game, lots of fun and relaxing, but can’t play it while listening to audio books/postcasts etc as the “sound off” toggle doesn’t work and the app always has sound which stops playback from other sources on my phone :(

### 4/5 — Very enjoyable, with some road bumps

*2026-07-01, version 1.1*

The game is smooth and consistent until around puzzle 144. I had to redeem points for hints to do the entire puzzle for me because although I correctly filled out all of the boxes it wouldn’t count the puzzle as solved. I’ve hit the same problem with 152. Overall the game is great, but some of the “master” level puzzles with ?’s are broken.

### 4/5 — Love the Game, No Ads, Minor Glitches

*2026-05-30, version 1.1*

Like other reviewers, I absolutely love this game. It’s something to pass the time and no ads makes it much better than most! However, there are minor glitches when solving master level puzzles. 

Kudos to the developer on this amazing game!

### 3/5 — Great game but…

*2026-05-29, version 1.1*

Why does it not show as the game is completed when the grid is actually complete?
In the UNLIMITED MODE, I think there’s a bug as it does this all the time. 
Also, there are grids that as soon as they are displayed to start playing, I’ve noticed that some squares are IMPOSSIBLE TO FILL. I have a picture of this!
Also, another irritating bug is that when you play with sound checked off, it still plays a sound when you complete a block which means that if you want to listen to music while playing in silent mode, you can’t listen to music!!!
3 stars because of that!

### 3/5 — Buggy!  Best part, no ads

*2026-05-28, version 1.1*

The sound won’t mute — annoying.  Worse, though, the app won’t acknowledge viable solutions to some of the games — and if you exit the level, it deletes your moves and resets the level.  I’m stuck on level 136, which I’ve solved at least twice, but the app says I haven’t (I have a screenshot that proves it).  I tried contacting support but the email address doesn’t work.
Also if you try to use a hint, it’s almost impossible to see what the hint was — it just blinks and disappears.  I do love the lack of ads though.

### 5/5 — Perfect

*2026-05-05, version 1.1*

This app was exactly what I wanted. A good game with great UI, zero micro transactions, and no ads. Truly perfect in every way. Being able to unlock new themes and stuff is amazing as well. Easy 5 stars.

### 4/5 — good just some bugs!!!

*2026-04-30, version 1.1*

i really like it!! lack of ads is so incredible and the game itself is super relaxing with the ui being understandable and pretty. one thing is the audio! I tried to turn it off in settings but it is still playing it for some reason? I like playing the game with music on in the background and when the games audio comes on it pauses my music. if there is anyway to fix this the app would be perfect!!

### 4/5 — Great Ad Free Puzzle App

*2026-04-30, version 1.1*

Great app! Love that there are no ads and no annoying pop-ups. I do, however, agree with the other reviews regarding the glitches. Additionally, on the master level, there is more than one way to solve the puzzle but I can only move forward when I have the “exact” answer. This has happened a few times now, especially when there are blocks of unknown value. Unfortunately the hints don’t help too much if there are multiple spaces that aren’t “correct”. Really enjoy the game and would greatly appreciate these bugs being fixed.

### 5/5 — Unbelievably free

*2026-04-27, version 1.1*

I can’t believe this app is this good and also free!
