# Gamification and Immersive Experiences: A Gamified Approach for Promoting Active Aging
## 3. Gamified Platform for Active Aging
### Gameful Experiences  
The application Twist enables users to engage in various activities, earning points and achieving victories based on their performance in the experiences offered. As users accumulate points, they advance in rankings, level up, and unlock achievements, encouraging sustained activity on the platform. Additionally, a forum feature allows users to connect, fostering a sense of community. The platform offers two main types of experiences:  
* Games: These quiz-style activities address various topics, providing immediate feedback on users' answers. Designed to stimulate cognitive function, promote positivity, and entertain, these games contribute to users' mental well-being. Upon completion, users earn points and victories if they score the highest. * Challenges: These immersive experiences feature 360-degree virtual tours, providing information about visited locations and concluding with a brief questionnaire to enhance attention, memory, and concentration. These challenges aim to create sensory-rich experiences that transport users to different environments, engagingly stimulating cognitive function. The application offers six games and challenges: Enigma, Tandem, Triviland, Matquiz, Strolling the Streets, and Strolling the Clouds. We present the developed games and challenges as follows:  
* Enigma: focuses on improving verbal skills, maintaining cognitive alertness, and reducing the risk of cognitive decline by leveraging the brain's language capabilities. This activity combines word games with puzzles. Three of the five questions presented involve crosswords, requiring users to fill in blanks with letters that align horizontally and vertically to form words. The remaining two questions are puzzles promoting memory, patience, relaxation, and stress relief. Users drag words onto images displayed on the screen, completing the puzzles interactively (Figure 1). * Tandem: One of the most well-known games for exercising memory is the matching game, also known as \"memotest.\" Tandem is a card-matching game where the user flips two cards simultaneously. If the images on the cards match, they remain face-up; if not, they are turned back over, and the user tries again. The objective is to remember the location of the images to match them successfully. The cards feature images of famous landscapes from the Canary Islands, adding an educational and nostalgic dimension. Users who recognize these places engage their ability to evoke memories and personal experiences, enhancing both cognitive stimulation and motivation (Figure 2). * Triviland: a general culture quiz combining true-or-false, multiple-choice, and puzzles. One of the puzzles focuses on popular proverbs from Spain, which is particularly effective as these savings are widely recognized among older adults. This activity helps users recall familiar proverbs, stimulating and enhancing their memory (Figure 3). * Matquiz: Mathematical games are excellent for stimulating the mind, exercising memory, and enhancing the intellectual activity of older adults, contributing to the prevention of cognitive decline. For this reason, Matquiz is designed as a mathematical game that combines simple arithmetic questions with mathematical puzzles (Figure 4). * Strolling the streets: Immersive experiences significantly enhance cognitive stimulation. Strolling the Streets is one of the challenges featured in the application. This interactive virtual tour uses 360-degree images of the city of San Cristobal de La Laguna on the island of Tenerife. As users progress through the tour, they encounter points with information and interesting facts about the locations they visit. At the end of the activity, a quiz on the tour's information is conducted to determine the user's score for the challenge. This experience helps improve attention, memory, and concentration. Additionally, if users recognize the places they visit, their motivation increases, as seen in the Tandem game, making the experience more engaging and enjoyable (Figure 5).
