The rules are simple! Guess your opponent''s number in turns. The first
player to make a correct guess wins!
Use the hints and make accurate guesses quickly and with the least
number of turns. This is a simple, but intellectually demanding
1.Set your own number (Play Number)
2.Guess your opponent''s Play Number using 10 numbers (0~9), and press CALL. (Choose 3 numbers if you''re playing 3 digit mode)
3.A hint will be provided each turn based on your guesses.
4.Based on your hints, make the correct guess before your opponent does, and aim for Numer0n (a correct guess)!!
~Types of Hints~
EAT…Both the guessed number and its position in use are correct.
BITE…The guessed number is correct, but not its position.
If the answer is 730
Guessing 137: 1 EAT, because 3 is being used, and in the correct
position (second digit).
1 BITE, because 7 is being used, but the position you guessed is not
correct (it''s being used in the first digit, but you guessed its being
used in third digit)
1 is not used, so it''s neither an EAT nor a BITE.
Therefore, the hint "1 EAT 1 BITE" will be provided to you.
*You won''t know which number is an EAT or BITE. Figure it out based on
your previous guesses!
*The same number will not be used more than once in a Play Number.
