Ratings and reviews

I was thrilled to find this game again! I originally had it on my PC in 1998 (X-SUMS98) and played it almost daily. Eventually I couldn't get it to work on my new PCs. (I think the last time I tried was around 2009). I now have successfully installed it on my phone but would love to have it on my PC again. I'm currently running Windows 10 Home. Do you have a new PC version available?

Exactly what I was looking for. I'm used to solving full page puzzles and this is the only free kakuro app that even comes close. Every other kakuro app on Play is tiny, and doesn't really reproduce the experience of playing on the page. Love it. Best kakuro in the Play store. AND, I had to come back here on my own to say so, there doesn't seem to be a rating function within the app, devs. Not a complaint, it seems every other game bugs you until you rate.

It is kind of hard to solve a puzzle if you don't know which cell is highlighted. I mean, the highlighted cell looks just slightly different shade than the other ones. I couldn't even get get around figuring the controls.
