Big Bang Theory fans, this one is for you! Six years after the pair last appeared on screen together, Leonard and Penny are back and this time they’re swapping science for strategy and going to war over mobile game night.
The Big Bang Theory co-stars, Kaley Cuoco and Johnny Galecki, have reunited in a playful new commercial for Royal Kingdom, a mobile strategy game that promises big action without the need for Wi-Fi — or a credit card.

The 60-second spot, shared by Royal Kingdom on Instagram, opens with the pair gearing up for a traditional board game night. But Galecki suggests trying something different — and from there, everything goes off-script. Board games fly, routers are unplugged, and the living room transforms into a full-blown celebration of mobile gaming freedom.
While it’s a fun ad for the game, the real treat is watching Cuoco and Galecki slip back into their familiar on-screen rhythm. Their chemistry is effortless, with over-the-top reactions and comic timing that call back to their sitcom days — no laugh track needed.
The spot also gave die-hard Leonard and Penny fans a glimpse into the couple’s life post show, with the couple happy and seemingly set up in a family home away from the apartment block that was central to their lives in the show.
It’s Galecki’s first on-screen role since The Big Bang Theory ended in 2019, making the commercial feel like a small but satisfying reunion for longtime fans. Cuoco posted about the shoot on Instagram, writing, “This was so fun to shoot! Back together with my buddy JG,” with Galecki replying, “I adored this day with you, my dear. XO!”
It might only run for 60 seconds, but for Big Bang Theory fans — especially Team Leonard and Penny — it’s a punchy hit of nostalgia with just the right amount of chaos.
