It runs fine on a tablet and ok on a phone- they load DOSBox for you, and you may have to answer a question or two about your monitor capabilities (Hello, throwback) but you'll have access to one of the largest libraries of really good, really old school games know to man.
The best part? You don't have to download. You just click, it loads, and you play. Perfect for when you're away from home or just want to climb into the way back machine. I've already found six games I used to love, and played them all over again. If I get tired of it, I just hop to the next game.
So if you need a major mental break, surf on over. You won't be disappointed :). YW.
