The Geogame The Green Treasure is a mobile trading card game for families with children aged 6-12. The game can be played all over Germany during a walk of about one hour. Plants with special characteristics should be found in this game. These grow in completely different places - they just have to be found.
The characteristics are different values on things like curability, if you can eat it, aesthetics and others. These characteristics show deliberate parallels to discussed criteria in nature conservation.
The players use the photo-function on their smartphone or tablet to document their discoveries, to get a digital trading card and to sort them into different treasure chests.
The value of the discovered plant can’t be known from the start. This is different to other collection games. The value depends on the perspective. The Foxglove might be a valuable medical plant, but is unsuitable as a food product. Even the dandelion can still surprise the player with unexpected values. The aim is to fill several treasure chests with suitable discoveries, for example fill the curability-chest with medically valuable plants.
Every discovery can surprise: in which aspect is the plant especially valuable? To answer this, the game’s website can be helpful. It can be visited from everywhere with your smartphone or tablet.
But every discovery also requires a decision: into which treasure chest should you sort the discovered plant? Finally every treasure chest should be filled.
For the ideal use of a discovery you have to consider which chests can be filled easier and which chests are difficult to fill within this area. In addition you have to consider which other plant discoveries are to expect. The game mechanics leads the player to engage properly with the characteristics and the discovered species and consequently getting to know local biodiversity.
