How to play Numbers Chain?

Numbers Chain is a fast-thinking math challenge:
Start with the first number, then keep applying the new operation shown on the screen before time runs out.


How it works:

• Game begins with a single number (e.g. 10).
• The next screen shows a math operation (e.g. +2). You must enter the result (12).
• That result becomes your new starting number for the next step (e.g. if the next operation is /4, you must type 3).
• Submit each answer before the timer runs out or the game ends.
• If you enter the wrong answer: game over.

Earn points for every correct step. The longer your chain, the higher your score!
