How to unlock the Researcher achievement in Jewel Quest - Definitive Guide
But the most important aspect of this is you can lose as many times as you want as you have unlimited continues; if you're having a nightmare just click restart the level on the pause menu. If you do this within the first 8 moves then you won't lose a life. (Thanks to cherryontop420 for that) It will get slightly easier the next time and just complete the whole run through one final time and your achievement will pop.
Unfortunately after all these levels and you get one screen of text and nothing more to celebrate your grind through this long, long game!
Try and only play a few levels at a time or your brain will frazzle, it's extremely tiring!
You will get this achievement upon completion of the game for the 5th and final time. On your fifth time through (oh what a nightmare) you will have the black faces, and you will have the broken pieces making this time through pretty tough. On top of that, you do not have the option to buy your way to the next level after 3 failed attempts. Good luck on this achievement. Here's a small tip: Before making your first move, look at the way the puzzle is set up with the broken pieces. If it looks like it will be too much trouble, quit and try again... you will not lose a life. Keep doing this until you find a puzzle that is set up nicely to your needs.
Infinite lives trick
Here is a little trick for infinite lives which will help with the game as well as the Game Master achievement. This was found by Skuff in the forums: "Every 50,000 points gets you an extra life, simply get close to that amount, i.e 49,850, 99,850, 149,850, and so on... then on purpose lose a life... start the next round, do 2 - 3 moves till you get your extra life, then restart round, your score will reset to the previous amount, i.e 49.850 but you will keep the extra life, simply rinse and repeat.
