If you take it as a challenge, it can very well challenge you. If you consider it as your guide, it can act as a trainer, who will always stand by you while improving your memorization skills.
A little on the background of this game..
The digit span task exercises your verbal working memory. Scientists refer to working memory as the cognitive system that allows the temporary storage and manipulation of information. Verbal working memory is involved in many everyday tasks, from remembering your friend's telephone number while you enter it into your phone, to understanding long and difficult sentences. Think about it; how could you understand a whole sentence if you couldn't remember the words at the beginning long enough to connect with the words at the end! Verbal working memory is also thought to be one of the elements underlying intelligence (or 'IQ'); thus, the digit span task is a common component of many IQ tests, including the widely used WAIS (Wechsler Adult Intelligence Scales).
Performance on the digit span task is also closely linked to language learning abilities; improving your verbal memory capacities may therefore help you to master a new language or to expand your vocabulary. Though the purpose of this activity is improvement in Memorization, many people feel that improving this index has compounding benefits for working memory as a whole and even improves behavior which includes paying attention, staying on task and avoiding distractions.
The average digit span for normal adults without error is seven plus or minus two. But a lot more is possible with a trained memory. Solomon Veniaminovich Shereshevsky (1886–1958) had an amazing digit span of over 70.
