A portable handheld and/or wearable screenless electronic game (10) device with at least one proximity sensor. The proximity sensor detects a proximity of the game device (10) to an object (10b) and/or detects a proximity of the object (10b) to the game device (10), such that the game device (10) detects a relative proximity between the game device (10) and the object (10b). The game device (10b) changes game state or configuration in dependence on a proximity trigger signal, the proximity sensor providing the proximity trigger signal when the object (10b) is detected within a minimum threshold relative proximity to the game device (10).
