Mums and Dads, more iTots entertainment for you and your child!
iTots Memory Match is a classic game of match-the-tiles using beautiful full colour photographs, along with sounds to match.When a match is made, a voice reads out a word describing the image - your child can not only see the matches, but hear them as well!Audio is available in US, UK, AUS.
Games are timed, with the best 5 times written to a scoreboard so you can keep track of progress. If your child is finding it too easy, turn up the difficulty level - 4 levels are available, with the difficulty determined by the number of tiles displayed (10, 12, 18, 28).
