So I can move between devices and don't need redo the same puzzles over and over to unlock the new ones.

I never really got into sudoku before, but since I've discovered Cracking the Cryptic's channel last week, I've become addicted to their videos! So I downloaded an free app on my phone on Monday and so far have completed 6 easy puzzles at work (during my breaks of course), but my best time was 28 minutes, the worst 75(!!) Are these games (the other 5 included) also solvable for beginner sudoku players like me? And how helpful are the hints for me?...

Okay, I'm reasonably intelligent, but these one and two star puzzles are frustrating. I wound up looking for a clue to puzzle 41. It says that after 'initial moves' R8c9 can only be a 1. R8c9 is a given digit (a two). It also says that 3 must be locked into two cells. I don't see how, there's 5 cells a 3 could be in with nothing to rule 3 out of other boxes....

Hello, I think being able to create your own puzzle and then solving it would be a great addition. Maybe also have a place where you can solve other player made puzzles as well. But I really like the UI and the tools that come with this game and would like to be able to input puzzles then able to solve them as well. I dont think you can already do this if so let me know how! Otherwise I think it was be a great thing to add....

When I mouse over a puzzle, each cell I hover over is automatically selected. From the "Tools" explanation it sounds like it's supposed to require a click and drag. Is this a problem with the Mac version? I would go try it on my PC but I only have an interest in playing this on my Macbook anyway. It also makes my laptop run hot which is ridiculous for a game that can be played in a browser......
