You may recall a few years ago we posted about a crowdfunded mathematical board game called Three Sticks. Well, the team behind it are at it again and have a new concept for a game, called Mind Your Numbers.

The game involves using the numbers 1 to 9, and twelve symbols (three each of +,×,-,

**÷**). The challenge is to combine the symbols and numbers in the right way to get a higher score than your opponent. It requires fast calculation, strategic thinking and a bit of luck.Their IndieGoGo campaign hopes to raise enough money to go into production, and they have 7 days left to take pre-orders and donations in return for goodies. It’s also possible to make a donation which results in not you, but a worthy school in rural India, getting a copy of the game.

Watch the video below for an idea of how it works!
