What is 21x?
21X is a light, fast paced card game that fuses Blackjack with algebra.
Like Blackjack, you'll be dealt 2 cards with the objective of getting them to add up to 21. However, the cards you're being dealt, have a twist to them... they're algebraic formulas!
It's a perfect gift for maths loving friends and family members, a fun algebra learning tool for schools and fantastic for avid newspaper puzzlers.
