BiDictionary game introduces user generated word space to grow, maintain and explore. Users navigate 2D / 3D word space to add / delete words of the language or link / unlink the words for 2 chosen languages or to learn words of other languages (foreign words), etc.
There is also alternative input method (besides keyboard) by navigating in 2D / 3D dictionary matrix like surfing in word space and inserting BiSound / pair of BiSounds respectively.
User can either choose BiWord or get random one to guess / uncover its BiSounds and gain score. Different kind of hints are provided to guess current covered BiSound (universal phoneme) of the BiWord - a hint showing distance between chosen and covered BiSounds in colour value, a hint showing the direction from one to another and both hints together. Also extra hints are BiWord size (the number of BiSounds in the BiWord), uncovered BiSounds (previously guessed or uncovered by the Enter key of the keyboard) and the width of covered BiSound letter, which is different for each BiSound alphabet (there are 4 BiSound alphabets available - BiLatin, BiCyrillic, BiArmenian & BiSlashes).
If user doesnt want to see disclosed BiWord at all, the disclosure parameter must be set to 0 in the settings. User also can guess the BiSound by pronunciation, using microphone (instead of the keyboard).
