The game comes with four identical sets of ten paintings, each depicting a different scene full of small hidden objects. Each of up to four players or teams uses their own set, placed on cardboard easels. Paintings are identified by a number so that everyone can load an identical scene onto their easel. One player draw a card from the deck and the card shows a letter. Everyone gets the time of a sandglass to write down as many things beginning with that letter as they can find in the scene. Each word can be used only once also if objects with the same name can be identified inside the picture.
Once time has expired, players read through their lists. Any object on multiple lists scores just one point for those who wrote it, while any item unique to a single list scores three points.
The game, originally published by the Italian company Editrice Giochi, is now published in a multilingual version for the European market by Interlude (with Ystari as copublisher) in a very smart tin box.
All the paintings and the artworks of the game have been created by Marianna Fulvi and Elena Prette.
