Dyseggxia (Piruletras in its Spanish version) is a mobile game that helps children with dyslexia overcome their reading and writing problems by the means of fun word games. All exercises in Dyseggxia have been scientifically designed to target reading and writing errors specific for dyslexic children.

The exercises have been evaluated by a group of users with dyslexia and are targeted to help improve difficulties caused by dyslexia. To do so, we have combined current pedagogical strategies with the results of an analysis of written errors made by children with dislexia. Dyseggxia offers:

— More than 7,500 different exercises (2,500 for English, 2,500 for German and 2,500 for Spanish).
— Five difficulty levels: initial, easy, medium, hard and expert. These have been designed according to word frequency, word length, morphological complexity of the word, and the number of similar words in language.
— Exercises in Spanish, English and German.
— Graphics showing the learning evolution.
— Accessories to customize your penguin.
— Each level contains several exercises from 6 types:

 — Insertion: a letter is missing in a word and must be inserted from the available answers.
— Omission: there is an extra letter in the word that must be deleted.
— Substitution: there is a wrong letter in the word that must be changed by one of the possible answers.
— Derivation: the user is presented with several possible endings to a word and must chose the correct option.
— Sentence separation: several words are put together, and the user must identify the breaking points between words.
— Transposition: the syllables or letters of a word are presented in disorderly, and the user must arrange them properly.

Dyseggxia now includes exercises both in Spanish and English! Easily choose the language you want to play with in the home screen.

No entiendo como una aplicación tan útil para la educación de nuestros niños no ha recibido tanta atención! Excelente trabajo, recién leí sobre el proyecto y me identifico con Luz Rello.
