Blackcat - my elder DD really did learn the multiplication facts completely and thoroughly with bigbrainz. She became the best in her class at competitive games with multiplication and she has retained that knowledge for a couple of years now. But she never ever managed to complete the final retention and she would end up a screaming teary mess. She doesn't find the graphics distracting at all (none of my kids do). But the noises are extremely stress/doom inducing, for me anyway... She'd end up too busy feeling panicky to actually respond fast enough.
