Math Games with Bad Drawings: 75 1/4 Simple, Challenging, Go-Anywhere Games―And Why They Matter

This is quite a fun book. I like it because it is full of very fascinating games, though it contains a few hard ones, such as “Quantum tick-tack-toe”. The author also wrote “Math with Bad drawings” and “Change is the only constant”, both of them are very engaging. By the way, his drawings aren’t really that bad. A few of them contain the funniest jokes I’ve seen in my life! I would recommend you to start reading “Math Games with Bad Drawings” after you turn 10.
