Microgaming has been in the "online gaming" scene (read: gambling on your phone or tablet) for a while now. At Mobile World Congress, though, it's showing its portfolio of titles for smartwatches.
I went hands-on with the tech, and can confirm that it all totally works.
With a quick tap on your smartwatch, you spin a roulette wheel. As you can imagine, you either win or lose real money (depending on how lucky or unlucky you are that day).
I'm personally not a gambling man, but it's clear that gambling on a smartwatch is possible if the control system for the game is simple enough.
It doesn't look half bad, either.
