What are binary puzzles?
A binary puzzle is a logic puzzle in which numbers should be placed in boxes. Most grids consist of 10x10 boxes, but there are also 6x6, 8x8, 12x12 and 14x14 grids. The aim is to fill a grid with ones and zeros. In a given puzzle are already some boxes filled. You must fill in the remaining boxes which must respect the following rules:


RULES
1. Each box should contain a "1" or a "0".
2. No more than two similar numbers next to each other in a row.
3. Each row should contain an equal number of zeros and ones (14x14 grids at each row/column 7 ones and 7 zeros).
4. Each row and each column is unique (No two rows and columns are the same).

Every binary puzzle has only one correct solution, this solution can always be found without gambling!

The first click on the empty field sets the field to "0", a second click to "1", a third click empties the field.

Simple rules but hours of puzzle fun.

TIPS
Find duos (2 same numbers)
Because no more than two of the same digits may be next to or placed under each other, duos can be complemented by the other digit.

Avoid trios (3 same numbers)
If two cells contain the same figure with an empty cell in between, this empty cell can be filled in with the other digit.

Fill rows and columns
Each row and each column has the same number of zeroes and ones. If the maximum number of zeroes has been reached in a row or column it can be filled in a one in the other cells, and vice versa.

Eliminate other impossible combinations
Make sure that certain combinations may or may not be possible in rows or columns.

### 3/5 — À améliorer

*2025-10-29, version 1.7.7*

Les différents niveaux sont très bien mais il y a des grilles à au moins 2 solutions qui respectent les règles et si ce n’est pas la solution qui est prévue le jeu ne l’accepte pas. Deuxièmement il est impossible de revenir au jeu à la fin de la pub il faut quitter l’application et la réouvrir pour recommencer un jeu. La petite croix sur l’écran de la pub est inefficace

### 4/5 — Logic challenge

*2025-08-12, version 1.7.7*

This puzzle is great. Each game doesn't take that long but it gets you thinking and feels so good when you get it out. This version is very easy to use...helps if you get absolutely stuck and doesn't inundate you with ads. Highly recommend

### 3/5 — Still ads after buying

*2025-07-23, version 1.7.7*

I bought the game, but every time I start it I need to restore purchase or else I keep getting ads. Really annoying. The game itself is very good.

### 5/5 — Tamazu

*2025-04-04, version 1.7.4*

J’adore… peu importe le nom!

### 5/5 — love it

*2025-01-29, version 1.7.3*

fun game, good for my brain, love how few ads there are

### 5/5 — Top puzzel

*2024-12-21, version 1.7.3*

Heb reeds enkele levels gespeeld en ervaar geen enkel probleem .. toppie dus

### 5/5 — Great puzzle.

*2024-10-11, version 1.7.2*

Never heard of it before, but once started I want to keep challenging myself.

### 1/5 — Slechte puzzels

*2024-09-18, version 1.7.2*

Puzzels zijn verkeerd ontworpen, rijen en kolommen kunnen niet uniek opgelost worden, of oplossing wordt niet aanvaard door de app (wordt dan niet gezien als opgelost)
Zeker NIET aan te raden!!!

### 3/5 — Adverts even after paying

*2024-06-05, version 1.7.0*

Even after paying unless you go to setting and restore purchase every time it’s opened,  it defaults to unpaid and shows adverts!

### 5/5 — Binero

*2024-05-02, version 1.7.0*

C’est génial
