A 15-year-old from Seattle, USA, has struck gold after selling a card game he invented as a child — turning an idea born during family game night into a multi-million-naira fortune.

Alex Butler was just seven when he dreamed up Taco vs. Burrito, a quirky, food-themed card game. This year, he sold the rights to Wisconsin-based toy company PlayMonster, the makers of popular titles like Farkle and 5 Second Rule. 

The sale figure remains undisclosed, but Alex admits he’s already thinking about investments and maybe a flashy Lamborghini.

“It’s not that important to me,” he told The Seattle Times. “I just wanted to get the most value out of it.”

Interestingly, when he created the game, Alex wasn’t even a fan of tacos or burritos. Inspired by hits like Exploding Kittens, he began testing prototypes at local coffee shops, with his parents, Leslie Pierson and Mark Butler, cheering him on.

Pierson, a seasoned entrepreneur who once pitched a product on Shark Tank, launched a crowdfunding campaign that pulled in $25,000 — far above their expectations. With about $30,000 worth of stock, they listed the game on Amazon, and it took off, raking in $1.1 million in its first year.

Over the years, Taco vs. Burrito sold more than 1.5 million copies, topped Amazon’s game charts, and inspired two expansion packs. But managing the growing demand became overwhelming, prompting the family to sell.

“We’ve had offers before, but PlayMonster shared our vision,” Pierson said.

PlayMonster CEO Jonathan Berkowitz was stunned when he learned the game’s creator was a child. “The characters are brilliant, the gameplay is fun for all ages — and it’s rare for kids to beat their parents in a game the parents still enjoy,” he noted.

For Alex, teenage life goes on — only now with a millionaire’s bank account. “I just want to invest… and maybe get that Lambo,” he said with a grin.
