Now, just months later, he's done it - for the "first time" in 37 years, he's made a game all by himself - and he wants everyone to play it and help "spread the word". It's called 'SHOT2048' and is available on the App Store and Google Play.
So, what's it all about? Here's the official description, along with some screenshots:
"The purpose is to shot the same number to make 2048, but aim for more. Tap to move the number left or right, and release your finger to fire the number. If you hit the same number, they will be combined and the numbers will be added. The game is over when the numbers stop in the red game over area in the foreground."
Why not give it a go yourself and let us know your own thoughts in the comments.
