Great for little tikes.
My 4 year old took this package of games and started it by himself and has not put it down for a week now. He is very excited at what he can create and he challenges family and friends to competitions with his game and he usually wins.

Great to keep him occupied on long trips! No adult intervention needed, so I highly recommend this for the kids under 7 and it is good for boys and girls.

good game for my 4 yr old
My son really liked the mini games on here. It's not his favorite...he loves mariokart and cooking mama but he still comes back to this one now and again. very simple and basic minigames and very age appropriate for 3-4 year olds, great for younger children new to the ds.

Two boys' review: Safe, simple and fun games for the youngest DS players
Both of my young boys have a Nintendo DS. I bought this game to rotate between marathons of Mario Kart DS and superhero games.

My kids weren't interested in this game at first, but quickly warmed up when they tried the piano playing mini-game. They also enjoy the drawing and coloring mini-games.

This is a good game for young players. I like that there are many mini-games, so this isn't a one-trick pony. However, I can't imagine kids over 8- or 9-years old would find this engaging.

If you are looking for more games for young boys, check out my Amazon Listmania List, "Young boys' Nintendo DS games."

great game!
My five year old son loves this game! We need to limit the amount of time he can play it he loves it so much. It is very creative and not your typical video game. A+

A great game, but buy Smart Kids: Playroom and get this game and Smart Girls: Playhouse for just a little bit more.
This game is a lot of fun and your 3-4 year old will love it, whether you have a girl or a boy. Your 2.5 year old might like it, too - but it might be too easy for your 5 year old. Regardless of the gender of your child, you should consider shelling out a little more for Smart Kid's: Gameclub, which contains this game, Smart Boys: Gameroom and Smart Girls: Playhouse.

At any rate, the mini-games in this game are:
play the piano
picture match
free drawing
color a pre-printed picture
find the differences in two pictures
put together the puzzle
bop the monsters
play instruments
match the sounds (sort of an easy "Simon")
picture match
counting
train station (my daughter's favorite, your kid will love it if her or she likes Thomas!)
car driving (use a map to drive the car to your destination)

The games sort of range in the fun factor, and none of them track performance or save any pictures or music beyond the end of the mini-game. I find this sort of frustrating but my 3-year-old doesn't seem to care.

The best part is the free drawing game - I've been looking for one of these since she first held my DS stylus and tried to draw in signature box in BrainAge!
