One of the specializations in the space in which I create deals with the field of playing in learning. Two projects in which I took part were the design of escape rooms, one at the Passage Center (a game within a game) and the other at the Beit Ariela library (the crown challenge). The process of working on each of them took about a year, most of the time was devoted to research, formulating a central theme, creating a route and formulating stations and user experience. I did the design of the game stations and the tightening of the order of operations with a professional outside party in the field of building this type of spaces The "game within a game" space allows 15-25 participants to play simultaneously and solve one big problem. It is not a closed space and the use of mobile phones is allowed, each station combines electronic and mechanical elements together with high-order thinking puzzles In the second space, the "Crown Challenge" was designed and built in the Rambam Library (a Torah library) as part of a desire to make the contents of the library accessible to the general public through a game Groups of 4-8 participants go through a route waiting for Maimonides' crown and what happened to it, which brings them to learning through play
