SIEVE:Prime Number Game
I thought a game where you guess prime numbers might be fun, so I made it on impulse.
目次
What kind of game is it?
It’s a game where you choose the prime number from four options.
The other three numbers are all composite numbers.
Since there’s a time limit, the game maintains a constant sense of tension.
You need to efficiently eliminate the wrong choices, so while the rules are simple, solid calculation skills are required.
It might be just right as a brain-training game.
There are four special abilities called skills that give you advantages as you progress through the game.
Because each skill has a cooldown, there’s a layer of strategy in deciding whether to save them or use them aggressively.
How to Play
Basics
- Press Start Game
- Click (or tap) the prime numbers
That’s the minimum set of rules.

Advice
One of the three characters will point out which number is prime.
I don’t really get prime numbers…
but guessing one out of four?
Leave that to me!
It’s fine while the numbers are small,
but once the digits pile up, that’s just impossible.
Prime numbers?
Too easy.
50/50
Reduces the choices to two options.
Check
You can make one mistake without triggering a game over.
However, the effect disappears even if you answer correctly.
Time +
Extends the time limit.
Impressions
Since play time is recorded, it’s also fun to play the game as a kind of RTA (real-time attack).
That said, its resistance to cheating is extremely low.
Because it’s possible to cheat in almost any way, serious competition among a large number of players would probably only work offline.
