A schematic illustration of the game interface.
In each round, players place 12 columns of dice (three dice per column) into 4 slots one by one. They win points in a slot if a horizontal or a diagonal line of the slot contains the same dice. The points from all 4 slots are added up and converted into monetary prizes (win or loss).

Behavioral expressions of within-session chasing.
(A) when to stop, (B) probability of changing stake, (C) change in stake size, and (D) speed of play. For panel (A), relative likelihoods are the conditional probabilities of stopping after a loss and after a win, normalized per player by the overall probability to stop, e.g. p(stop|loss)/p(stop − overall) and p(stop|win)/p(stop − overall). Error bars stand for 95% within-subject confidence intervals.
