Kalina,
"it would be more fun...." .to study that way. I have used Anki for the past 3 years, and review the words almost every day. At the moment I am reviewing 50 - 70 words a day, which only take 10 minutes. I uploaded another 30 new words today, and the frequency seems to be review a first time, then on the 3rd day, 5th day, and then longer intervals.
Some people put the audio file on the flash cards, but I find it takes too much time to create.
