The swiss army knife of parenting!
I love the range on this App~ Wonderful graphics, voice over, sound effects and best of all, difficulty settings! I can hand this to my 3 year old niece and she is guided along as to which dots to tap in order with hint indicators and my son in Kindergarten who can run this on Hard mode without any hints. Price is right too at less than a penny a puzzle. Lots of other category and settings is nice. Not sure why you would want to turn off the display words but autoplay is a nice feature to turn off so my niece can brag about what she just created!
