Steve Wozniak found out about the money years later, long after he and Steve Jobs had built Apple together. The whole thing started with a game about bricks.

Atari wanted an arcade game where a paddle knocks a ball into a wall of bricks. Most of its games ran on more than 150 chips, and every chip cost money, so the company offered a bonus for each one a designer could cut. The job went to a young technician named Steve Jobs. Jobs couldn’t design the board himself. He called his friend Woz, offered to split the pay, and promised Atari a prototype in four days because he had a trip to Oregon coming up.
