Funded by the Hong Kong Jockey Club Charities Trust — Chief Executive's Community Projects, the e123 website (www.e123.hk), which is dedicated to the elderly and their carers, revamped to enhance its interactive functions in 2019. In 2020, we have further developed a new set of cognitive training games.Over the years, SAGE has been working unremittingly to produce cognitive training games with our professional team. As early as 2007, the first online game — "Brain Gym" was launched. It is the first-ever website in the Chinese society that advocates cognitive health of elderly people. With the success of Brain Gym, e123 has further developed 25 new cognitive training games, Exercise Your Brain, with more interesting elements, attractive graphics and multi-training functions. From character and graphic design to game content, the 25 new games enable players to experience the authentic Hong Kong. Images of signature local places and iconic items are shown in the games to help elderly players recall their precious memories and boost cognitive function. Meanwhile, the life-like tasks in the games also train players' with daily living skills and self-care ability.
