Brain Training App (1–10)
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.
Bubble 10
A math game where you add numbers to make 10: “Bubble 10.” Balloons with numbers rise from the bottom—tap balloons that add up to 10.
Be careful: if a balloon touches the jagged spikes at the top, the HP gauge on the left will decrease.
It’s simple brain training that even elementary school kids can play.
Don’t rush—pop the balloons steadily.
It’s a race against time!
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!
Brain Test

The game app “Brain Test” lets you enjoy plenty of trick-based puzzle games.
Popular around the world, it looks like a casual game you can play in short bursts, but it’s filled with puzzles that surprisingly require real brainpower to solve.
Even problems that seem as simple as riddles won’t yield the correct answer unless you think a little outside the box.
With many levels available, you can keep training your brain without getting bored.
It’s a game that both adults and children can enjoy, so give it a try!
Pitapon
Introducing the brain-training fitting puzzle “Pita-pon.” Pita-pon is a game where you fit a variety of prepared pieces into a square grid so they all fit within it.
It’s similar to a jigsaw puzzle, but Pita-pon isn’t straightforward because the pieces come in all sorts of shapes.
It’s a game that demands imagination and flashes of insight.
It’s simple, but once you start, it’s really fun—so give it a try!
Karakuri Korokoro
“Karakuri Korokoro” is a game where you build your own route to the goal using various contraptions.
It feels a bit like the NHK show “PythagoraSwitch.” The ball you need to deliver to the goal is affected by gravity, so if your contraptions are in equilibrium, nothing will move… it really makes you think.
It’s a highly recommended brain-training game that both kids and adults can get hooked on.
