Taken as a simple and cheap "solitaire" (i.e single player) game, Poisoft Thud Card is enjoyable, easy playing. I do say that as someone who spent many, many hours playing Hearts on my old Windows PCs over the years, though. I like time wasting card games. As such I'll probably keep coming back to Thud Card as long as I have my Switch. Or, at least, until a developer releases a Hearts game on the console.
Thud Card is a complicated card game with very poor instructions and a lack of interesting reasons to return to the game, it's hard to see anyone having an enjoyable time with this game and as such I couldn't recommend anyone going out of their way to try Thud Card.
Poisoft Thud Card is a card game that is simple enough to learn quickly and behaves like most card games do. Unfortunately it quickly becomes dull, as its lack of content stands out after a while and the fun provided quickly runs out. For a game that is supposed to fill empty moments with fun bouts of play, Poisoft Thud Card does the opposite.
Poisoft Thud Card is one of those kinds of terrible games that is bad in a way because it's boring and that it requires others to suffer in order to get any mileage out of it. Sometimes a broken game can be a worthwhile experience because they can create really amusing moments. Poisoft Thud Card goes past the standard for being bad; it becomes anti-entertainment.
