About this game

Love logic deduction games and number puzzles like sudoku?

Riddle Stones is a game of logic that will train your brain: like crosswords but with squares and numbers. The game is based on the asian riddles known as picross, griddler and nonogram. It’s a real mind challenge wrapped in a fun experience where you need to think and use your brains to succeed.

To decipher our puzzle grids, you will use numbers indicating which squares to activate in each grid based on simple rules. Each number tells you where to add squares in a row or a column. You can compare it to sudoku or crosswords with more fun brain training. You will learn easily, progress rapidly and quickly get addicted! It will blow you mind!

Riddle Stones offers a fascinating cross-over between crosswords, sudoku and other puzzles based on numbers where you cross the hints to find which squares to activate. But be careful and think right, if you tap the wrong square, you will trigger a trap!

Fans of picross, nonogram, griddler, paint by numbers rejoice and enjoy Riddle Stones...
Solve grid cross-puzzles by logic & deduction! PLAY NOW!


Riddle Stones is completely free to play, but some in-game items such as extra lives require payment.

What! IS! HAPPENING!?!?!? The entire game changed since yesterday??? ! I got a new phone yesterday and I knew I'd go back to the beginning, but now there's a map? Tiny grids? Can only play with my phone on landscape orientation? This sucks! I have loved this game for the LONGEST. Playing boards in the 2,000's. Lately the ads have become ridiculous! 30 second commercial after every single board, that you can't back out of/dismiss. So frustrating. I'm sad that I'm losing interest because of it.

Got frustrated, it's too easy. But the controls often lead to misclicks that damage hit points. I prefer designs where it doesn't tell me if I filled in a square wrong, so if I misclicks, I just take it back and do it over. Many puzzles have x prefilled, so it's entirely too easy to find rows or columns with only one answer already spelled out. Like zero or ten columns, the puzzle gets too boring if there's too many of them. Also the tutorial lasted way too long, and didn't have options to skip if I already know how to play picross, which feels condescending. Wish I could just buy the premium Nono Logix game this developer released before, but it's not on the store anymore.

I'm really disappointed in the number of ads being shown. It takes longer to wait on ads to finish than it does to play some levels. There needs to be a significant reduction in the number of ads. To play a level with 4 boards, I get 2-3 30 sec ads. And if I make a mistake, there is another 30 sec ad. Too much.
