How to unlock the 20 Leagues Under the Ground achievement in Microsoft Minesweeper - Definitive Guide

This took me many tries until I found a surefire method to make it past level 20. There's no way to guide you, but I can offer some tips and advice.

1. Always horde your pickaxes, dynamite, and maps until you absolutely need them. I found myself with 10 pickaxes and 40 dynamite on level 20, so I easily cheesed my way through it.

2. Identify patterns with number combinations. Two really common ones are 1-2-1 and 1-2-2-1. With the former, there's always going to be one trap parallel to each of the 1s. With the latter, there will always be one trap parallel to each of the 2s. There are others, but I won't list them here for the sake of simplicity.

3. Clear out as much of each level as you can in case you find extra hearts, shields, pickaxes, dynamite, or maps. Sometimes you will have to guess where the trap is, so make sure to do this after you have reached the exit in case you end up low on hearts.

4. For levels 1-10, you can probably cheese your way through by just clicking the exit and having your character automatically dig to it. I found this out while grinding for doors and monsters.

5. Most of all, don't forget to take breaks. My first real attempt I made it to 20 and died right next to the exit, which made me furious. If you're like me, anger makes you impatient, and thus you're more likely to make mistakes. You can exit during a level, and it'll save your progress for next time.

I also want to point out that you can use the Windows 8 version to unlock this achievement. Then when you load up the Windows 10 version, it'll automatically unlock.

We go into adventure mode and go through the first 20 levels, it’s better not to rush and collect everything on your way, opening doors and killing monsters. It is better to take care of things and use them only as a last resort. If you reach the exit with 1 heart, the next one will be 4 again. Take Sheets only when the entire level is completely open, they go to the next one in full. Once you pass level 20 you will receive an achievement.
