NUM: Bulls & Cows Number Game

Guess the hidden 3-digit number. Every call returns two clues, HIT and BLOW. Rule numbers out, think it through, and crack the code in as few calls as you can.

NUM is the classic number-guessing logic game also known as Bulls and Cows or Hit & Blow, rebuilt from the ground up for short, focused play.

HOW IT WORKS

• The answer is 3 different digits from 0 to 9, like 482.

• HIT: a digit that is right and in the right place.

• BLOW: a digit that is right but in the wrong place.

• Keep calling until you get 3 HIT.

Your first game is a guided one, so you learn the rules by playing, not by reading.

TODAY'S PUZZLE

One puzzle a day, the same for everyone. Solve it in 6 calls and build your streak. Missed a day? Your streak survives one day off.

LOOK BACK AFTER EVERY GAME

See how many candidates each call left and which of your calls was the best call. Find the moment you could have cut it shorter.

PLAY AGAINST COM

Five COM rivals, NANA, RIKU, KAEDE, SORA and TOWA, each with their own strength and habits. Their strength is shown as an average number of calls, with no hidden handicaps.

TRUMP CARDS

Turn on trump cards for a battle and each side holds one special move to use once: two attack cards that probe your opponent's number and two defense cards that rework your own.

PLAY WITH SOMEONE

• Pass one device: take turns on a single phone.

• Two devices nearby: connect two phones directly. No internet and no account needed.

A quick brain game for a coffee break, a commute, or a head-to-head with a friend.
