In some embodiments, the disclosed subject matter involves a system and method relating to dynamically sending local visual landmark information from multiple end user devices to a central server that is controlling an augmented reality (AR) experience. The local landmarks enable better alignment of the AR representations across devices. Multiple players may dynamically synchronize on shared landmarks that “anchor” the AR experience. The landmarks may be dynamic, transitory, and do not require pre-modelling of a location. Other embodiments are described and claimed.
