Horrible I tried it and it was horrible and hard to use it does not deserve that one star I gave them

Charlotte Livings

Rubbish On any device it is absolutely rubbish! I did not get it and i even read the instructions! I prefer chicken coop fractions get that instead! This game is NOT useful when your teacher said you need to work on your fractions! I would do - 100000000000000000000 if i could!!!!!!

## Fractions

Fractions is an original game of reflexion combining mental calculation and speed.

At start, a grid is generated randomly and has squares with each 4 values under differents forms (fractions, percentage, integer, decimal, subtraction, addition).

For exemple, value 0.6 can be represented like that in Fractions :

- 3/5

- 6/10

- 12/20

- 9-8.4

- 7-6.4

- 60%

- …

All of theses forms are an equality in Fractions.

Thus, solve a Fractions grid consists to find all equalities between squares’ values in contact on the grid.

To do that, you should make roll values of squares clockwise by clicking on it.

For players that want more complexity in game, levels 4, 5 and 6 will be a perfect challenge since grid’s squares are shuffled at game start. So, to solve grid you should also make drag and drop with squares !

To solve grid as fast as possible with least possible actions will let you to realize high score between Fractions players around the world.

Fractions has also the following functionalities :

* Share high scores throungh the world

* Configure your player name thanks to Preferences menu available on Fractions home screen

* Consult Fractions high scores around the world with your personal ranking displayed

* Consult stats during grid resolution

* Help for levels 4, 5 and 6 to mark squares well placed by a little orange square and squares well placed with values in good order thanks to little green square at left top of squares.

* An elegant help menu lets you to see how to play to Fractions. Changes between screens are realized thanks to edges that are in bottom of the screen or by flip on screen right to left or left to right respectively to go to previous screen or next screen.

## 2048 Infernal

We are pleased to introduce a new sensational and original edition of the famous "2048".

This version will make you go crazy! Here we present the rules.

This version will make you go crazy! Here we present the rules.

The game takes place in a grid of 25 cells (5x5).

You can add the whole numbers in the sequence:

2 → 4 → 8 → 16 → 32 → 64 → 128 → 256 → 512 → 1024 → 2048

You can combine the fractions:

½ → ¼ → ⅛ → 1/16 → 1/32 → 1/64 → 1/128 → 1/256 → 1/512 → 1/1024 → 1/2048

You can not combine numbers and fractions together: this is a great news! Basically it's like to play two games within the same grid!

To win you have to reach "2048", or the fraction "1/2048".

Are you ready to face this new incredible challenge?

What are you waiting for? Download the game and accepts the challenge now!

Challenge your friends and compare your score with that of the best players from around the world!

## Right Brain × Left Brain

"Let's promote collaboration between your right brain and left brain!"

What is the secret of cleverness?

Is it that the right brain which manages intuition is developed?

Or is it that the left brain which manages logic is developed?

In fact, the secret of cleverness is not that one brain is developed, but that both brains can cooperate smoothly.

It is said that that Dr. Einstein had the remarkable cooperation between the right brain and left brain.

"Right Brain x Left Brain" is a game which enhances cooperation between your right brain and left brain.

【Game Introduction】

(1)Color × Character

This is a game which enhances cooperation between the "color cognition" which is a domain of the right brain and the "character cognition" which is the domains of the left brain.

Can you choose correctly, without mixing up the contents and the color of a character?

(2)Figure × Calculation

This is a game which enhances cooperation between the "pattern cognition" which is a domain of the right brain and the "calculating ability" which is the domains of the left brain.

Unlike the usual numerical calculation, the number is replaced with the figure.

If it is a number, you are an easy numerical calculation, but can you solve?

(3)Number × Numeral

This is a game which enhances cooperation between the "number cognition" which is a domain of the right brain and the "numeral cognition" which is the domains of the left brain.

Can you recognize the number of a numeral and numeral quickly, and touch it?

The content was developed to help students to explore quantities, learn numbers symbols, compare numbers, and skip count . The technological innovation for Everybody Counts: Learning Numbers with the MOTO Family far exceeds any digital publication on the market and includes:

• instructional animated video segments featuring the MOTO family -- four engaging characters that portray computational math symbols,

• dozens of interactive learning opportunities,

• digital manipulatives and games,

• a specifically developed writing/drawing tool to allow students to complete interactive tasks and show their progress without leaving the iPad environment,

• Teacher Notes on every page that guide teachers on how to get the most of each page and task,

• technology that allows students to practice key skills, put answers directly on the page, and get instant teacher feedback, and

• the capability for multiple students, each with an individual password, to share the same iPad.
