“Weight Sense,” a game where you identify weights across seven levels. (7 types × 4 pieces each)
Small boxes that differ slightly in weight. Use the weight as a clue to guess the number. There are various ways to play, including original games and card games like Memory. It’s a simple yet deep game that anyone can enjoy—one that doesn’t rely on memory or strategy.




Poker You Build Yourself
Instead of playing poker by relying solely on luck, use the card values as clues to find the numbers you need to make a strong hand.

Pig’s Tail
Here’s a video showing how to play the tactile game “Pig’s Tail” (full version from start to finish). “Pig’s Tail” is a tactile game where strategy comes into play. Your hand is the key—could there be a dramatic comeback!? It takes about 20–30 minutes to play, but as the game progresses, the pile in the center grows higher and higher, making for a nerve-wracking experience. Sharpen your senses and do your best not to end up with the towering pile in the center…!
Indian Poker
You guess your number based on its weight. It’s a game of chance where you use weight as a clue. When a parent’s guess is way off, is that a chance?
Cooperative Games
“Cooperative Game” is a game where players arrange numbers 1 through 7 in order based on their weight. It feels a bit like being a batter in the batter’s box. When you get it right, everyone goes, “Ooh!”; when you miss, everyone goes, “Aah” or bursts into laughter.
