Proven effectiveness

A joint research experimental trial was conducted by JICA and Keio University. The findings confirmed that children who used Think!Think! for the 3 month trial period improved significantly on their math scores and IQ test scores compared with the control group which did not use Think!Think!

Example Games

Shadow Light


These problems consider how a 3D object casts a shadow. Spatial awareness can be classified into four categories: perception, cross-section, projection and mental folding. This type of problem naturally fosters the ability to project by using the theme of "shadows" that children are already familiar with.

Sword Swipe


These problems consider the cross section of a 3D object when it is cut. By experiencing numerous cross-sectional views of typical solid objects such as cubes, pyramids and cylinders, the ability to visualize cross-sectional views of shapes is developed whilst having fun.

Find the Square


These problems require the user to find the vertex of a square among the points. In order to find a shape by yourself using only the points as a guide, you need the ability to plot imaginary lines. This problem will develop one's sense of being able to plot imaginary lines using squares as a theme.

Crazy Crocs

Trial and

The objective of these problems is to reach the goal without finding the crocodile. This is one of the best educational materials for developing a sense of thinking e.g., how to proceed despite taking a hit, being able to logically divide options by saying "if it's not this way, then it must be this way" and to work backwards from the goal to find a solution etc.

Photo Detective


The objective of these problems is to arrange the stuffed toys correctly using photos as clues. Because language isn't used, even children in the lower grades of elementary school can enjoy thinking logically and developing their skills by combining multiple conditions together e.g. "This must go here because of XX".

Snack monitor


These problems require the player to determine whether the number of candy pieces on the left and right are the same or not. Students are encouraged to think about the number of candy pieces on the right-hand side by moving them around in their minds and cultivates an attitude of thinking creatively and grasping number graphically.


What differences are there between Think!Think! compared with the general digital learning materials?

Think!Think! differs from many other apps which help you acquire skills and knowledge in subjects such as calculation. Think!Think! is an educational material with a core design that fosters "thinking sense" and "motivation to learn".

"Thinking sense" is a very important ability for effective learning. For example, a child with good "thinking sense" will realise that when learning multiplication and division, they are in fact "dealing with the same thing" but from a different angle. From this, the child will be able to independently grow rapidly. Furthermore, as we live in a generation where anything can be learned online, and rather inexpensively, there is a large difference in academic performance depending on one's level of motivation. Think!Think! fosters "thinking sense" along with "motivation to learn" by tackling high-quality puzzles and three-dimensional and graphic problems, all whilst having fun.

Can a digital application be more effective for learning than paper-based content?

Yes! While using Think!Think!, users are able to take full advantage of being digital and exceed the limitations of paper-based materials. The convenient format ensures that anyone is able to improve their skills.

In order to develop thinking sense, for example, to "assemble a 3D shape mentally in one's head", it is necessary to have that ability as a sense. Think!Think! reproduces the sense that "a person with a good sense of thinking" has, and with movement, this enables anyone to visualize what was once difficult to understand on paper. This is an innovation in educational materials with thanks to the evolution of technology. In addition, by taking advantage of the merits of app based technology, such as the presentation of problems tailored to each person, "real time" feedback that suits the characteristics of young learners, and a system that appears to be a game on first glance, you can expect greater educational effects than paper based materials.

Of course, paper-based materials have their own merits. At Wonderfy, we believe that it is important to recognize the advantages of both paper-based and app-based educational materials. Given that, we have also created our "WonderBox" service, a STEAM education home learning material that combines analogue materials with digital learning. Please feel free to check it out.

I'm not good with critical thinking or STEAM subjects, so I have little confidence in my ability to teach them to children.

The strength of our app materials is that children can work on them totally by themselves. There's no requirement for a parent or guardian to explain anything.

Think!Think! is designed so that rules can be understood intuitively, and the problems are tailored to each child's individual level and thus, explanations from parents or guardians are not necessary. Should your child have a hard time with a particular question, you can guide them towards the "hint" button on the screen.
Each time your children solves a puzzle, they can see a real time representation on the screen. For example, how a 3D object is cut to make a cross-section, or how a net is assembled. Even if at first, the concept is difficult to understand, they will gradually be able to visualize abstract ideas and concepts in their head by themself.
If you're a parent or guardian, please encourage your children's efforts by saying "That's great! Keep trying!".
