7-Eleven, Inc. and The Tetris Company have teamed up to celebrate the 40th anniversary of the Tetris game, inviting customers to visit their nearby 7-Eleven, Speedway, and Stripes store to snack and stack.

Beginning today, customers across the United States who purchase participating products via 7Rewards, Speedy Rewards or 7NOW Delivery will have a chance to win one of 20,000 limited edition Tetris handheld gaming devices, designed and manufactured by My Arcade and shaped like a 7-Eleven Slurpee drink.

7-Eleven has also unveiled limited edition co-branded merchandise including retro t-shirts, hoodies, hats, stickers, keychains and totes—all available on the retailer’s online merchandise store, 7Collection. A limited quantity of gaming devices will also be available for purchase.

“As we mark the milestone 40th anniversary of Tetris, we are excited to announce our partnership with 7-Eleven, another iconic brand beloved across generations,” said Maya Rogers, CEO of Tetris. “This collaboration celebrates our spirit of innovation and delivers fans with a new, fun way to experience Tetris.”

Loyalty members who want even more chances to win can score seven extra entries by purchasing items like Slurpee drinks, Big Gulp and Big Bite hot dogs, as well as any variety of Red Bull, including the original energy drink, sugar-free, and the new Red Bull summer edition Caruba elderflower.
