Palindrome Quiz

A “palindrome” is a phrase that reads the same forward and backward.
For example, “gake de kega” (“injured on a cliff”) in Japanese.
A palindrome quiz is a game where you look at an illustration and come up with a palindrome related to it.
It sounds simple, but it’s surprisingly challenging! Still, the feeling when you nail one is amazing, so try playing with friends or as a parent-child activity.
You might even discover a brand-new correct answer.
Brain Training App (1–10)
Matchstick Puzzle

The classic “matchstick puzzle” that everyone’s tried at least once is now available as a smartphone app, so you can play anytime, anywhere.
It used to be featured on TV shows quite often, too.
It’s a game where you move a set number of matchsticks to transform them into a specified shape—but unless you think flexibly, it can be hard to find the correct answer.
Give it a try with friends while you’re waiting around!
Roll the Ball
“Roll the Ball” is a game where you rearrange the path tiles within a 4×4 grid so that the ball in the top-left corner can roll to the goal.
It’s simple, but it gets progressively harder with each level, so you’ll need to use your brain to solve it.
It’s also a solo, focus-friendly brain-training game, perfect for filling small pockets of time.
2048

The brain-training game “2048” is, as the name suggests, a game where you aim to make 2048.
In a grid of 16 squares, numbered tiles appear at random.
By combining these numbers, your goal is to ultimately create a 2048 tile.
When tiles collide, they multiply and merge into a single tile.
In other words, colliding two 2s becomes a 4 tile.
The game is over when every square in the grid is filled with number tiles.
It’s a mobile game you can quietly enjoy on your own.
Fill One-Stroke Puzzle Game

“Fill One-Stroke Puzzle Game” is a game where you trace various shapes in a single stroke from start to goal.
If you like mazes, you’ll probably enjoy it.
The difficulty increases with each level, so rack your brains to find the single path.
If you’re confident, try tackling the harder levels right from the start!
