Sometimes, Puzzles can be very challenging to solve, which is why we have prepared the following advices in case you stumble on a very difficult grid to crack!


  1. Try to fill rows or columns with higher digit numbers first to have an easier visibility on the grid and easily deduct them
  2. Draw tough puzzles on either a piece of paper, or a digital document, to have an overview away from the game that may unlock the solution in your thought process
  3. If there are more than 1 possible solution, use your instinct and try your fortitude! 
  4. Use Boosters, Continues & Medkits!


If all the above doesn't help, try posting a screenshot of the Puzzle in the RiddleStones Forums where you may get help from a fellow Riddler.
