Puzzle by Nikoli X Sudoku achievement guide (Windows 8)

Puzzle by Nikoli X Sudoku for Windows 8 has five achievements for 200 gamerscore. All of the achievements can be unlocked in the demo or the full version of the game. This guide will walk you through unlocking all five of the achievements as easily as possible. 

The first achievement can be unlocked by quickly scrolling all the way through the help menu. The next achievement is unlocked by clearing five puzzles in shuffle mode. These puzzles will count toward the next two achievements for clearing ten and twenty of the game's twenty unchanging puzzles. After clearing shuffle mode move on to clearing the other fifteen puzzles in the game. Each cleared puzzle will have a crown under the puzzle number. The achievements for clearing ten and twenty puzzles are misleading. They actually require you to clear ten and twenty different puzzles. The twenty puzzles in the game do not change and the solutions are all listed below. The achievement you will likely unlock last is the achievement that requires you to have a total play time of one hour. This achievement is buggy and usually does not unlock at one hour. It usually unlocks closer to two hours. If it has not unlocked by the time you have finished all of the other achievements you can simply let your device idle until it unlocks.
