Bests & Worsts Reviews from Amazon

I bought both these items for my 3.5 yo - so this review is based on this age range. While the concepts are similar, my son (and I) like Mighty Mind better than MindWare Imaginets for the following reasons: Mighty Mind cards are numbered to show increasing difficulty Mighty Mind comes with cards that are numbered. As the numbers progress, so does the difficulty. This is important for younger children because it starts them off with the easier ones and helps build confidence. They can progress without getting too frustrated in the beginning and giving up. Imaginets cards are not numbered. Yes, you can flip through the stack and kind of see which ones are easier, but the numbering system of Mighty Mind is really helpful for gradual progression and confidence building. Mighty Mind is actually a puzzle that encourages creative reasoning Imaginets comes with cards that show exactly which tiles go where to create the picture on the card. The child simply needs to find the matching block and put it in the right place as shown on the card. Mighty Mind only shows the OUTLINE of the image you are trying to create. It is up the to child to figure out how to fit the pieces together to create the picture. Mighty Mind is more like a real puzzle, where Imaginets is just rote recreation of an existing lay out. Mighty Mind has multiple "solutions" Imaginets has only one solution, which is to re-create the exact picture on the card. Mighty Mind can have multiple solutions to each puzzle (especially with the more difficult cards), depending on how the child fits the pieces together. Mighty Mind is more like tangram, Imaginets is more like art The tiles in MM are basic: squares, triangles, rectangles, circles in various colors and sizes. Imaginets has "odd" shapes, like zig zags and curves. I think Imaginets would be better for an older child that is creative and wants to make free form art pictures with the tiles. My son is not there yet. The amount of tiles overwhelms him and most of the cards are too difficult for him so he loses interest quickly. Magnetic board of Imaginets was too strong I loved the idea of the magnetic board, but in reality it ended up being a hinderance to my son being able to use this toy. The magnets were too strong, so it was very hard for him to move the pieces around the board. Also, it was hard for his small fingers to pull the tiles off the board because they stuck so well. Obviously, this would not be an issue for an older child, but my son is within the recommended age range, and it was an issue for him so that's why I'm mentioning it. One thing to keep in mind: if your child is a "perfectionist" and/or does not have highly developed fine motor skills and manual dexterity, s/he might get frustrated because the tiles can move outside the lines and the child is trying to butt them up against each other. This is especially true if your child is used to working with puzzles that "lock" together, like jig saw puzzles. There have been multiple times where my son figured out where all the pieces went, but would get upset when he would lay a tile down and the adjacent tile would get pushed outside the lines. Not a huge deal - it will ultimately teach him refinement of his fine motor skills, but it can be frustrating. As such, this is not yet a toy that he can work on independently for very long. But that will come with time and increased skill.
