After I published City of Zombies I was spending a lot of time running 'Zombie Maths Days' in school across the UK. Teachers kept asking me if I had anything to specifically help children practice the 12 times tables, so I created a mini stand alone game based on CoZ called Times Square. It was published in 2016 and can be played with or without a copy of City of Zombies. I have also designed and published Alana's Animals, a pre-school yearly years numeracy game suitable for children as young a 3, but still fun for adults to play ;) Alana's Animals is also available from Genius Games who are publishing it in the US.
