Amazon However, six months later, they were still discussing and refining the game. This ultimately led to Leslie and Alex's dad, Mark Butler, establishing a Kickstarter to help get the game off the ground. Leslie and Mark then formally established a business to begin manufacturing the game — and they made Alex the majority shareholder, perThe Seattle Times. They began by selling it independently on Amazon, where it sold out in a week and soon became one of the top-ranked games on the site. Taco vs Burrito — which has sold 1.5 million copies on Amazon — is based on the premise of creating the "weirdest and wildest" meal possible using a variety of gameplay cards, including wild cards like "Food Fight," "Tummy Ache," and "Trash Panda," per the game'sofficial website. The game is intended for 2 to 4 players, ages 6 and up, and a round takes about 10 minutes. After over half a decade of overseeing the manufacturing and distribution of the game themselves, the family was ready to take a step back. They decided to sell the company to the Wisconsin-based company PlayMonster in a full buyout. The exact details of the sale have not been released. And how did Alex feel about the sale of his brainchild? It was seemingly all part of his plan. "It was never something that I've been attached to or anything. It's not super important to me. I just kind of wanted to get the most money out of it," Alex toldThe Seattle Times. "It was never something I wanted to do later in life," he added. https://people-app.onelink.me/HNIa/kz7l4cuf Alex — who is interested in sports, music production and video games — is currently working with his parents to invest the money made from the sale — though he jokingly told Leslie and Mark that he plans tobuy a Lamborghini, Leslie told PEOPLE.
