Tula is like a traditional card solitaire ported to piecepack. I found it so and so. I played four games and completed it once. Once I got only one tile after the first free tile. I had to use the mercy swapping rule twice, and it’s highly recommended unless you like to shuffle the tiles a lot. It’s a nice little solitaire game that’s easy to play, so I can see myself playing it again.
One Man Thrag has an interesting concept: it’s solitaire dungeon crawling game. That’s cool, and it works well, too. The game is rather luck-heavy, so it might not be for everyone’s tastes; I’m not completely sure how much I like it. Still, the theme works and it was fun to play, so I might actually try it again one day.
