【Over 50 problems per play】Trump card numbers become math problems? New 'Multiplication and Division' for competitive 'Speed' game

Analog game manufacturer TRYBE, in joint development and operation with Kids Project Inc., will release the latest work in their 'Ben-Game' card game series, 'Multiplication and Division Speed,' on May 1, 2026. The 'Ben-Game' series offers challenges in 'all genres of study' from early childhood education to university and research levels. To commemorate the launch, a limited-time sale will be held on their official EC site.

■ About 'Multiplication and Division Speed'

① Play the classic 'Speed' card game while solving math problems!

It follows the same rules as the classic 'Speed' card game, making it easy to understand. The difference is that the numbers written on the cards are 'mathematical expressions.'

Players stack cards that have the same number, or one smaller or one larger than the number currently on the field.

The first person to play all their cards wins.

② Can be combined with 'Addition and Subtraction Speed' and 'Fraction Speed'

This title is the fourth installment in the calculation series, following 'Addition and Subtraction Speed,' 'Fraction Speed,' and 'Math III Speed.' All adopt the same rules, allowing cards to be combined for play.

③ Over 50 'math problems' in 5 minutes

One play takes approximately 5 minutes, with quick決着. Although the rules are simple, each play involves over '50 calculations.' As cards are played, the field and hand constantly change, meaning an average of 5-6 calculations are performed for each card played.

Since it ends quickly, players often say 'one more time!' and their calculation speed naturally improves with repeated play.

■ What is 'Ben-Game'?

A card game series that offers challenges in 'all genres of study' from early childhood education to university and research levels.

3 Features

① All rules are based on classic card games
Subjects like Japanese, math, science, social studies, and English can be played with rules from familiar card games like Old Maid, Concentration, Speed, and Poker. Knowledge to be memorized and skills to be acquired naturally stick with players as they play. Since everyone knows the rules, no explanation is needed, and you can enjoy it immediately.

② Covers all genres from early childhood education to university and research levels
In addition to the five main subjects, the lineup expands to specialized fields like literature and Math III. Future developments include content at university/research levels such as astronomy and psychology, as well as preparation for certification exams and the bar exam.

③ The joy of competing in your得意分野 (specialized field)
As you play, you naturally learn, and the more you know, the more likely you are to win. This creates a virtuous cycle where winning leads to liking, and liking leads to becoming even better. Even in subjects you dislike, you might find yourself enjoying them a little more.
