Number Masters Game

Number Masters is a fast math game built around one question: can you do arithmetic quicker than everyone else at the table? Each round throws addition, subtraction, multiplication and division at you, mixed together as you go further, and you answer by picking the correct number from the choices on screen.

Getting it right extends your stairs upward and keeps you ahead of the water rising behind everyone. Miss a question or hesitate too long and the water catches up. Whoever has climbed the highest when it's over wears the crown — it's built for a quick round or two, not a long sit-down.

Controls

• Left mouse button, or tap on mobile — select the correct number

Tips

• Speed matters as much as accuracy — a fast guess can be safer than agonizing over a slow correct one if the water's close behind.
• Watch the operation, not just the numbers. Mixed rounds throw multiplication and division in among the addition and subtraction, and it's easy to answer the wrong one on reflex.
