Relationships have been left in tatters and wars have been waged, with many a dinner table erupting into violence over a simple game called UNO.
Keeping us entertained on long car journeys, rainy camping trips, and flights abroad since 1971, we've had 55 years of UNO to occupy our time.
Developed by Merle Robbins in Reading, Ohio, UNO's appeal is its fast-paced action, relatively easy rules, and those signature bright colors.
We've seen the game evolve a lot over the years, with a scrapped game show, a movie in production, and the beloved card game even being inducted into the National Toy Hall of Fame alongside pinball and the Magic 8 Ball in 2018.

The first official UNO World Championship took place in 2021, with one lucky victor walking away $50,000 richer.
Now, you can get your hands on another $50,000, just by playing UNO on your smartphone. We know how addictive gaming can be, and for those who have the UNO app, they'll know how easy it is to sink hours into it while constantly muttering, "I'll just have one more game."Calling for wannabe winners to register now, the UNO World Championship is asking for anyone, anywhere to enter. There are three in-person qualifying tournaments, taking place in Orlando on October 3, Chicago on October 10, and Los Angeles on October 17.
Still, you can enter from the comfort of your own armchair, with qualification also available via the UNO app.
While there's an element of luck to UNO due to what cards you're given in the first place, it quickly turns into a game of skill as you race to get rid of your cards.
The UNO World Championship is said to turn the classic card game "into an adrenaline-fueled tournament with the unpredictable, chaotic fun that has made UNO a true cultural phenomenon.”
As we're a modern age of technology, the November 11 finale will be streamed on Twitch, live from the floor in Los Angeles.
Telling us to shuffle the deck, Katie Buford, VP and global head of Mattel Games, cheered this year's competition and said: "At its core, UNO has always been about creating unforgettable moments around the table from epic comebacks to game-changing Draw 4s."

“The 2026 UNO Championship Series Tournament brings that excitement to the biggest stage yet, giving fans around the world a front-row seat as elite players battle it out to become this year’s UNO Champion.”
To celebrate the upcoming competition, Mattel has also launched a special line of Championship Series products, which even includes a championship belt so you can crown your own winner among you and your loved ones.
As the UNO name continues to expand, you can buy sets based on everything from KPop Demon Hunters to The Nightmare Before Christmas, X-Men to Wednesday.
Finally, there are free weekly tournaments being held on the UNO Mobile app until September 27, so you can brush up on your skills and see whether you've got what it takes to become the next champion of champions.
Let's just hope you get dealt a good hand.
