Guriddo is a great puzzle concept that anyone who likes number puzzles should try. If you like sudoku but want something new, try this game. There is a bit of a learning curve at first, but put a little bit of time into it and it starts to come naturally. It has such a good challenge and the daily and weekly puzzles are a great way to keep me coming back for more.

I'm not a fan of the redesign (not seen in the preview pictures above). The AI-generated backgrounds on the home page make the game feel cheap. The background from launch (as seen in previews above) wasn't in need of improvement. Edit: I'm glad that the developers fixed the contrast issue. Looking at it now, my review was a bit mean-spirited. I'm not the biggest fan of change, and the contrast issue was probably the final straw. Thanks for listening!

Hi Christie. The animations and the note contrast have been re-worked in version 1.18.0. But the home screen backgrounds? Come on, you see them for about three seconds before you're back in a grid of numbers 😄 They never touch the board itself.

This game really needs to gain traction. It's a very fun and challenging game for people who like more advanced sudoku/nonograms style puzzles where you have to think ahead 3-5 steps and consider how moves impact relationships with other parts of the grid in various ways. It's also a very clean interface, and the daily challenges tracking is enjoyable.
