La historia de la viborita o Snake (popularmente conocido y mas aun luego de la aparicion del Nokia 1100) es bastante interesante.
El juego aparecio en la decada del 70 donde el juego cobro popularidad y nunca se dejo de jugar. El juego consistia en una linea plana que iba creciendo en longitud conforme se iba "comiendo" los items. Luego aparecieron MILES de modificaciones de todo tipo, incluso aparecio Snake 3D que se distribuia con el telefono Nokia 6131.
Toda la historia comienza con Blockade , producido por Gremlin en 1976. La primera "viborita" que se programo en una computadora se llamaba WORM y salio a la luz en 1978 programado por P. Trefonas para la microcomputadora TRS-80 .
Año a año la viborita fue ganando popularidad hasta que llego QBasic. Este se distribuia con una version del adictivo juego llamada Nibbles (mas abajo les dejo el codigo). Desde ese momento se afianzo principalmente en el ambito de los programadores y poco a poco se fue metiendo en la cultura de todos.

Su historia en los telefonos se hizo prospera con Nokia.
La primera aparicion la hizo en el Nokia 5110 y era solamente un cuadrado sin forma. Solamente para telefonos monocromos.
Luego salio la version Snake II para el Nokia 3310 (solamente para telefonos monocromos). Aqui ya se veia una patron con forma de viborita. Luego aparecio en una larga lista de telefonos incluido el Nokia 1100.
Al tiempo salio Snake Xenzia. Para el Nokia 1600 y 1112.
Snake EX aparecio en telefonos a color. El nokia 6260 la tenia de fabrica.
Snake EX2 aparecio con la serie S-40 de Nokia.
Snakes 3D aparecio en N-Gage producida por IOMO. Permitia el modo multiplayer y venia preinstalada en toda la serie N de nokia.
Snakes III que esta re groso esta disponible en Nokia 3250, 5310 y 5610.
Snakes Subsonic salio el 22 de Mayo de 2008 para la nueva gama de telefonos Nokia.

Bueno, la verdad que todo lo que puse arriba era solamente para comentar un BUG que tiene el Snake del Nokia 1100 pero no queria que sea tan pobre jajaja. Hace muuuucho tiempo jugando me di cuenta del bug. La cosa es que el otro dia encontre mi Nokia 1100 tirado por ahi y recorde el bug y me gustaria compartirlo con ustedes.
Este bug sirve para juntar la cantidad de puntos que deseen. Hay que hacer lo siguiente.
Comenzar un juego nuevo (ejemplo: Clasico) en el nivel de dificultad que uno desee. Jugar un buen rato y sumar algunos puntos. Llegara un momento que no puedes mas y tendras que chocar indefectiblemente, en ese momento el programa hace titilar a la viborita unas 4 o 5 veces y te da el puntaje que hiciste y te dice si es un record. Aqui esta la parte importante. APENAS CHOQUES... cuando la viborita todavia esta titilando, debes apretar el boton C. Eso te mandara a un menu donde puedes jugar de nuevo, continuar, etc... presiona de nuevo la tecla C y elige el modo CAMPAÑA y comienza un nuevo juego. Apenas comiences el juego no hagas nada, no comas nada, no muevas nada, NO HAGAS NADA DE NADA. Presiona el boton C nuevamente y vuelve al modo clasico y presiona en CONTINUAR. Cuando hagas eso veras que la viborita esta chiquitita de nuevo pero el puntaje que tenias cuando chocaste sigue ahi, asi que es cuestion de seguir jugando y seguir acumulando puntos.
Este truquito lo pueden hacer MILES de veces. Asi tengo en mi celular un recor de 48.083 puntos con la viborita en modo Clasico.
ACLARACION: Este truquito solamente sirve en los primeros modelos de Nokia 1100. En los que son Gris con negro y tienen la pantalla Verde. Si intentas hacerlo en los que tienen la pantalla blanca o en los Nokia 1100b que tenian carcaza blanca y gris no te va a funcionar.
