User reviews

Love it but small problem

The new puzzle 2492 is impossible to solve. It requires a sum of 23 in 7 digits but the absolute minimum of 7 digits is 28. Solving the puzzle for a sum of 28 works, it appears to be a typo.

Easy to use

Tried several Kakuro games, and this is the best in my opinion. Been playing it for a few years.

This version is easy to use. Visually clear. Well defined buttons. Have found no problems with it. LOVE that you continue to add puzzles!

Ads every 2 seconds

This game used to be very good, but now there are ads constantly every couple of seconds during the game - makes the game very unplayable. There are even ads for this game during the game - pretty stupid. Good example of greedy developers ruining a game.

Ads while playing are evil

I loved this game for years. The ads in between puzzles are not a big deal, but now they’ve added adds in the middle of the game ? I can’t stand it so I have to delete the app. It’s not playable.

Ads!

Please offer a no ads purchase. This is the only issue with the game and the slightly annoying hidden 9 on the mobile version.
