This is a number puzzle where you must guess the hidden "mathematical equation" within 6 tries.
■ How to Play
When you enter a valid equation (e.g., 12 + 35 = 47), you'll receive a hint based on the color of the square.
Green… Both the number and its position are correct.
Yellow… The number is used in the equation, but its position is incorrect.
Gray… The number is not used.
Use the colors to narrow down the candidates and guess the hidden equation.
Only equations that make a calculation can be entered. Incorrect equations cannot be determined, so
**accidental entries do not reduce your number of tries.**
■ A New Puzzle at Midnight Every Day
The puzzle is determined by the date. Therefore, players all over the world will be tackling the same puzzle each day.
Once you solve it, you can share your result using an emoji grid. The answer itself is not shown, so
it won't bother those who haven't solved it yet.
■ The More You Continue, the More Fun It Gets: "Consecutive Day Record"
Your consecutive days increase only on the days you attempt the challenge (success or failure doesn't matter).
Even if you accidentally miss a day, the "lucky charm" will protect your record.
The calendar will show whether you succeeded or failed that day.
■ Another Question on Weekends
On Saturdays and Sundays, you'll receive a "Weekend Challenge" consisting of a 9-square grid with two operators.
This is separate from your usual single question, so you can maintain your weekday pace.
