Mario Vs. Toad in the Ultimate Race
Over five feet of track pieces.
View larger

K'NEX brings your favorite Nintendo game to life. Challenge your imagination as you create countless adventures building this set and watch Mario and Toad race through the complete, multi-level Mario Circuit Track in their super-fast motorized Wild Wing and Standard Karts. Mario and Toad zoom down and around the huge five-foot-wide course, through twists, turns, and jumps -- but they better be careful, because there are lots of moving obstacles, ready to knock those karts right off the track. Push levers to send the gaping jaws of the Piranha Plant reaching down, the growling Chain Chomp chomping across, or the mischievous Goombas waddling through, just like in the game, and watch as Mario and Toad try to speed past these obstacles to avoid getting hit for a chance at a victory.

Largest Mario Kart Wii Set

This building set includes a whopping 665 pieces -- all you will need, along with step-by-step instructions, to construct your very own scene straight out of Mario Kart Wii. Build Mario and his Wild Wing Kart and Toad in his Standard Kart, both decked out with real rubber wheels and super-fast battery-powered motors, plus four bonus collectible items from the game: a mega mushroom, golden mushroom, POW Block, and a trophy. The set also includes over fifty pieces of buildable, interconnectable track, in addition to the moving Piranha Plant, Chain Chomp, and Goombas obstacles. Colorful stickers offer even more creative opportunities to decorate the karts and track with sweet Mario -- and racing-themed art. All of the track pieces are compatible with other K'NEX Mario Kart Wii sets, so you can expand and customize your track by combining different sets for even bigger and more creative tracks. Collect and build all of the Mario Kart Wii figure, kart, bike, and track building sets -- there's a ton -- and compete with your friends on all of your favorite tracks from the game.

This set is very large, it is 5 feet in length. It has 665 pieces and it took me about 6 hours over 24 hr time period. I did it alone it would go much faster with 2 people. The instructions are just pictures and at times are not quite detailed enough. The one big suggestion I have is to open all the bags and separate the pieces with like pieces. They are not really grouped together with what they connect to. I didn't put the cars together until last and the bag looked to contain only car stuff. So all the time I was looking for the little black end caps for the guard rails and they were in that bag.

I put it together as the instructions state but I do think it would be great for kids to make up their own tracks too. If you already have K'Nex sets then these will work together. The cars go around quite fast and the track hold together well, I was afraid it may fall apart but it doesn't. The only problem if you can call it that the cars get stuck sometimes under the swinging traps.

I made a short video clip so you can see it in action after waiting 2 hrs for it to upload it told me it was too large.So you get a really fast look and not all the details I had pointed out. I had to put my ironing board by the table as it was too big for the table and I was not up to doing all that work sitting on the floor. There are so very many tiny pieces so beware of small children and pets. One of the wheels fell on the floor and my dog got it, he could have choked had I not seen it right away.

Overall this is a lot of fun. I have always enjoyed putting things together, I will admit at 56 yrs old it was a challenge at times. You will need 4 AAA batteries that are not included. My advice start early in the day to put this together.

My son loves legos and Mario, and the idea of combining the two thrilled him! He could not wait to start assembling the track when he saw this box. It really is massive, and takes up a good deal of space in his room. While the box says this is appropriate for ages six and above, I can't see the average six year old being able to tackle this project without a lot of adult help (which is part of the fun in my opinion, but beware!). The kit comes with almost 700 pieces in neatly packaged sections. The instructions are fairly straightforward - there was only one spot where we couldn't quite understand what the diagram implied. With adults and kids working together, it still took about four hours over the course of a few days. It's that big!
The track itself is neat. It comes with two cars and the means to build Mario and Toad for said cars. They are battery powered, and zip along pretty quickly along the track. The cars also zip on wood floors for added fun while the track is being tediously assembled.
Our main issue came with keeping the track assembled. The pieces just don't go together as well as traditional legos or racing track, at least with our kit. Every time my son would move the sliding piranha, that section of track would come detached. We'd get it back together and the little obstacle section would fall apart. It's good for about two laps around the track before some adjustments are needed. My son gets a little frustrated, but still says the track is a lot of fun.
Overall, it's a neat set-up. It has some twists and turns, the Mario characters and two zippy little cars. Building takes hours, but again, it's a nice project to work on together. Aside from the instability issues, I'd recommend it.

Don't get me wrong with my 3 star rating - there's absolutely nothing wrong with this Mario-themed K'nex set. The construction quality is good, the set is sturdy once assembled, and the cars and components will hold up to use over time even in the hands of rambunctious little ones. Assembling the set was fun, probably even more so for dad than for my 7 year old son, as he doesn't yet quite have the patience needed for an hour or two project getting a toy ready for play. The reason that I am not giving this a higher rating is because it simply isn't very interactive. My son was very excited when we finished building it and fired the cars up for their initial laps, and he really loved watching the cars zip around the track...for a while. But after the initial excitement wore off, I've found that he hasn't played with the set very much at all. Aside from watching the cars go round and round, there isn't really much to do with this set. There are a few pieces that you can use to "attack" the cars as they race, but all you're really doing is blocking the car so that it just stops in place. That's about all there is to do with this other than just watch the cars go.

Consider my review in light of your own child's interests and play styles and take it for what it's worth to you. My son tends to like hands-on, interactive, social play activities so this just doesn't really fit the bill for him and he has barely used it since the first day he got it. This will be one of those things he pulls out once every blue moon for a short spell and back in the box it goes. Your child may love it, but for us it's only "okay".

One last thing - the completed set is pretty big, measuring about 4' x 5 1/2'. Keep this in mind as you consider how practical it might be for you & your child.
