"Nimmer is a strategy game based on the game Nim, also known as the Match Game or the Marienbad Game. It pits the player against the machine. The game is turn based and consists of switching off 1, 2 or 3 lights per turn using the buttons on the metal box. The aim of the player is not to be the last to switch off a light. Nimmer was created by René Sommer over the course of a year and was exhibited at the third ""La Science appelle les Jeunes"" (english: Science calls the Young) competition in 1969. The game's title is a combination of ""Nim"" and ""Sommer"". As Nimmer was created in 1968, it is one of the earliest Swiss computer games in the CH-Ludens database. It is therefore not a video or digital game as we know it today: Nimmer comes in a PVC box measuring 40.5 cm x 30.5 cm x 13 cm, which can be transported in a suitcase. It has a number of separate logic blocks, such as the control circuit, the main memory, the calculation circuit, the input-output circuit (machine-player, player-machine communication) and the cheating detector.
