I’ like to introduce the how-to-play and tips of each Think!Think!(Hanamaru lab.) game in this blog.


This post is for OrangeOthello.

We can play this in the Standard Plan.


Description / How-to-play

The rule of this game is, so to speak, Othello.

The color is different from original Othello(black & white), but we will flip the purple stone all over with the orange stone.


Just for very beginner of Othello, the purple stones sandwiched between 2 orange stones will change to orange in all.


In this OrangeOthello, the number of stones usable is displayed on the right side of the screen.

Let’s change all purple stones on the screen to orange in a limited number of steps.

The tips for small children is to master the rules firmly.

What is different from ordinary Othello is that you can use multiple stones and turn over purple stones all.


The point is to predict what kind of placement pattern will be after the first step.

And, to find out where you can turn more stones looking at vertical, horizontal and diagonal lines.


It is important to practice a lot in the Think!Think!.

Of course, enjoying the actual Othello with your family is also effective.
