The schedule of rewards and penalties in the four decks of cards of the IGT, as introduced in [20]: The first block of 10 selections from each of the decks (out of 6 blocks).

Note: The average gains and losses are across all 10 selections. The gains on each trial range from $80-$120 for decks Dis50 and Dis90 (normally distributed in discrete steps of $10) and from $40-$60 for decks Adv50 and Adv90 (normally distributed in discrete steps of $5). In addition, the difference between the decks’ expected values increases with time. That is, after each 10 selections the average gain for the disadvantageous decks increases by $10 while the average loss increases by $25. At the same time, the average gain for the advantageous decks increases by $5 while the average loss increases by only $2.5.
