Particularly interesting:

"Sequence Recall: Words-Visual begins with displaying a list of 2 to 10 words on the computer screen for the patient to remember in order. After a delay, one of the words is presented again and the patient must click on a numbered line to indicate its position from the original list. Correct responses produce the "TA DA" sound and incorrect responses produce a wrong chord sound. The number of correct and incorrect trials is totaled. Task difficulty is modified by changing the length of the list, the number of times a list is presented, the amount of time to study the list, and the length of the delay between the presentation of the list and the presentation of the target word.

Sequence Recall: Digits-Visual begins with a list of 2 to 10 digits displayed one at a time on the computer screen. The patient must remember the digits in order. After a delay, the patient follows the same procedure described for words. Data collection and procedures for modifying task difficulty are also the same as for the words task."

In other words, the index-of-item-on-the-list tasks, something that's not available here or in the "brain training" programs I've seen before. Also, it could be possibly enhanced by including words off the lists (to check for false memories/recognition) or words from the previous lists (to check for perseveration).
