EQUAL

EQUAL is a quick mathematical challenge between 2 players using just a standard deck of cards.

By combining cards, players attempt to form a calculation to equal, or get the closest possible to, a randomly generated target number.
Drawing additional cards may help but, the more cards a player takes, the more they have to give to their opponent.

The rules are just a single page. 

The rules suggest using 2 dice to keep score but this can also be done with pen and paper (or even in your head).
