The concepts of heaven and hell for Hinduism in this article are not entirely accurate. 'Samsara' merely means the world. Hindu's do have concepts of heaven and hell. Hell or 'Narak' is a place ruled by the God Yama. Unlike other religions, Yama is not 'Satan', but a God, i.e he is not evil. He is virtuous and torments evil doers and lets good humans pass to heaven. He is assisted by an 'accountant of doings' called Chitragupta.
Heaven is more complicated. According to Hinduism, there are 7 levels of heaven. Samsara being the lowest level, that is the mortal earth. The level that all other religions associate with heaven is called 'Swarg' which is place of plenty and happiness. The highest level is God or 'Brahman' himself, when the spirit becomes one with God, and is thus relieved from the cycle of birth and death, i.e attains 'Moksha'.
