ZenBaki

A simple web-based game for your Twitch chat, no registration needed!
You will see a number in the circle and a simple operation below (+, -, *, /). Try to be the first guessing the result and write it on the chat.
You'll get points every time you guess the result, but beware! If you are  wrong you'll lose everything and the game will be over.

Notes: 

- If you guess later than others, there's no penalty.

-You have to wait 2 seconds between each try.

- Every time you fail you'll be excluded depending on your penalty count.
