Number Lock

Spin the dials and crack the code!

Number Lock is a relaxing number puzzle game from the makers of Word Lock. Every puzzle is a combination lock: swipe the golden reels to dial in the right digits, press CHECK, and watch correct locks snap shut in shiny gold.

FOUR WAYS TO CRACK THE CODE

• Number Lock: solve the sum and dial the answer. Some digits are given; work out the rest. Puzzles grow from simple addition to subtraction, times tables and division.
• Sequence Lock: what comes next? Spot the pattern (adding, doubling, square numbers, Fibonacci-style and more) and dial the next number.
• Logic Lock: follow the clues ("the digits add up to 14", "no digit is used twice"…) to find the one code that fits them all.
• Code Breaker: crack a secret code. Every CHECK locks the right digits and tells you whether each of the others is higher or lower. Can you do it in 4 checks?

A NEW DAILY CODE EVERY DAY

Crack the same 6-digit code as everyone else, once a day, for bonus stars and coins.
