Gamification tools are any software environment or platform used to implement game mechanics in non-game contexts in order to increase engagement. There are certain open-source software such as eThink LMS, Chamilo and Docebo, but without a deep understanding of the specifics of gamification, their use will be ineffective. If you are planning to introduce gamification for the first time, then the best way would be to contact an experienced gamification agency that not only knows how to work with the necessary tools, but also has extensive gaming experience.
