Sandbox games are all about building a Finnish one-family house according to Finnish construction standards. The situations, rules, conflicts, conditions, behaviour and programed tasks are all genuine and reflect real construction site situations and standards as closely

We first build the foundations of the house and then in Sandbox II we continue finishing the house from the foundations to the roof. Games are developed into RealXtend which is the Finnish virtual world platform.

Sandbox games are funded by The Finnish National Board of Education (FNBE). Read more:



The objective of the game is to better apprehend the construction of a house foundation for young students. The 3D environment is an ideal way to learn the building technique of a house. This a risk-free environment allowing errors. Learning from them the students have a better comprehension of construction technique and the real construction site.

Game is founded by The Finnish National Board of Education and developed by Koulutuskeskus Salpaus and LudoCraft
