I'd like to think that my "handheld radar" is pretty good these days, seeing as I have made hundreds of videos on them and likely written thousands of articles, too.
But this is one that slipped under the radar, and if you, too, are not familiar with it, then I hate to say it, but we've both missed the boat on this device.
This is a limited edition handheld made by MyArcade in collaboration with Tetris and Red Bull to celebrate the championships that happened in Dubai in December 2025.
During this event, Red Bull was doing a wide range of promotions, such as the world's first Tetris game in the sky, which is what took most of the attention in all honesty.

But this little handheld flew under the radar. 7,000 units were given to attendees of the final in Dubai, and 3,000 units were allocated to the online store, retailing for €34.99 on November 27th, which, as you can imagine, sold out in days.
So, there are only 10,000 of these made, which makes it highly collectable for handheld enthusiasts like myself. They are currently on eBay for around €75/$90.

Oddly, the handhelds for sale on eBay are all located in Germany and a couple of surrounding countries. I can see none for sale in the United Kingdom or the United States, making me believe that the majority was given to Europeans... or scalpers got most of them.

That said, this device plays a singular version of Tetris, comes numbered out of 10,000, features a 1.55" display, two action buttons that flip the shapes and takes 3x AA batteries.
The reason it went under my radar is that it had very limited marketing around the device. Red Bull & Tetris had enough on their plates during the month of December, and I completely missed anything mentioned about this device, like many of us.
But, it seems like the 3,000 people who ordered (or the handful of scalpers) are getting theirs delivered, and gamers are getting to experience what Tetris would feel like inside of a Red Bull Can. It's an absurd gaming handheld for sure... but that's kinda why I want it.
