Semideus is a rational number game engine that can be used to create games that aim to support the development of rational number conceptual knowledge and conceptual change processes. The gameplay is founded on tasks that require working with number lines implemented as walkable platforms of a mountain. In the game the player controls a character, Semideus, who tries collect gold coins that Goblin has stolen from Zeus. Goblin has hidden the coins along the trails of Mount Olympos. Semideus has discovered the locations of the coins, encrypted in mathematical symbols, and must race the goblin to retrieve the coins. Several rational number task can be included in Semideus games, for example number line estimation, magnitude comparison, magnitude ordering, and density awareness tasks. All the tasks are embedded into the game in an engaging way and games created with Semideus engine are designed to work also as non-invasive assessment instruments. Our validation studies have shown that the Semideus games can be used as assessment tools. In terms of embedded embodied interactions, the game character and other movable items can be considered as visual manipulatives that help players to concretize the mental number line and at the same time the playing behavior provides a window to player’s thought processes. Moreover, we have defined a semantic model about conceptual fraction knowledge that provides possibilities to model players’ developmental trajectories of rational number concept.

Magical (Making games in collaboration for learning) project has developed a Magos Lite game creation tool targeted for primary school pupils. Game creation with Magos Lite does not require programming skills and pupils can easily create educational games and exergames with it. Magos Lite provides tools to design side-scrolling games where action is portrayed as a side-view.
The game creation consists of deciding on the game type (fly or run) and game mode (time, survival or distance), selecting characters and other elements, creation of tasks (e.g. word matching, calculations, fractions, memory tasks), adjusting speeds and control sensitivity, and defining rules and scoring for collectibles, hazards and tasks. Game designer can also choose from predefined graphical assets to enhance game aesthetics. Games can be controlled either by traditionally clicking or by utilizing motion sensors of tablet computers by exercising (jumping or running).
Magos Lite is integrated into Magos web portal that is used for user authentication and authorization but it also provides users with access to produced games. In Games to Schools project we will continue the development of Magos portal and we will add especially game modes that support learning of fractions.
