PolyRules is a challenging sorting game where the rules change as you play. As you progress through the game you will encounter increasingly more complicated scenarios that challenge you in ways you can't imagine. The current release is our first prototype and we will update the game semi-frequently as we move towards a design that features tried and true game design to facilitate the cognitive benefits this game aids to provide. Researchers who are interested in using this game for their own studies please reach out to us to us through our support page for more information on how to best use this App. We have several ways to support you including a central server to store logs and automatic analytics which will be implemented in the coming weeks.
Twin Game
Read full descriptionHide full description
Twin is an engaging and incredibly popular board game built on the foundation of fun and challenging tasks for your mind. The game consists of cards, each with a set of symbols. Players are tasked with quickly identifying and finding a pair of common symbols between their card and the one laid out on the table. Twin tests your attention, concentration, and observant skills while simultaneously developing communication and interaction abilities. The game is ideal for the whole family or a group of friends as it is easy to learn but leaves plenty of room for strategy and creativity.
