ゲーム詳細
Kuku Doubt
7 × 7 = 81!?
Would you believe it?
Kuku Doubt is a fast-paced bluffing game that combines multiplication with psychological mind games.
The rules are simple:
A player announces the result of multiplying two cards.
Then the next player must choose one of three actions:
Doubt / Guess the Pair / Accept
- Doubt — Challenge the announced answer
- Guess the Pair — Name the exact two-card combination
- Accept — Let it pass
If Doubt or Guess the Pair succeeds, the opponent takes damage.
Be the last player standing to win!
Why You’ll Love It
Tense from the very first turn
Kuku Doubt gives players two different ways to attack:
Doubt and Guess the Pair.
That means even a truthful answer is never completely safe.
Every turn is filled with bluffing, deduction, and suspense.
Quick to learn, quick to play
The rules are easy to understand, and the game moves fast.
Once only two players remain, the game turns into a sudden-death showdown.
It is a great choice for groups who want a short, exciting game with constant interaction.
Easy to enjoy—even if you are not confident with math
A multiplication reference chart is included,
so players can enjoy the game without worrying about mental calculation.
Even if math is not your strong suit, you can jump right in and have fun.
