The present study investigates the effect of group gaze-cue interaction on the decisions, decision times and eye-movements of the participants in the game of beauty contest. The experiment is designed in the Group-Eye Tracking (GET) platform to create different gaze-cue sharing conditions, ranging from no gaze-cue to all gaze-cue conditions where each participant’s gaze location is visualized on all other participants’ screens. It is hypothesized that the anchoring effect, which is argued to guide the decisions in the beauty contest task, would be influenced by the increasing awareness of the participants regarding each others’ eye movements preceding their decisions. The results indicated that there was no gaze-cue sharing effect on the eye movement patterns and no significant difference was observed among the gaze-cue conditions for the decided value derived from individual choices. However, for all contest types it was found that decision times are significantly higher in the all gaze-cue condition. The indifference observed for guesses and eye-movements can be partly accounted by the reduced alertness due to repeated rounds of play. Higher decision times in the all gaze-cue condition might be due to the deception strategies that emerged and the dynamic re-anchoring of the "satisficing" guess according to other players’ behaviors revealed through their gaze-cues
