Center Stage G5:
Finish a Symbol Sudoku puzzle by placing the last symbol in the exact center of the board
This achievement requires that you complete a Symbol Sudoku puzzle by placing the last symbol in the space at the exact center of the board. This must be done in Daily Challenges. First make sure to select a challenge that has symbols, instead of numbers (you can tell by the icon). When the board loads, confirm that the center space is empty. If it is not, back out and load the board again (the filled symbols move around at start). Proceed to fill in the board, except the middle space. Save that for last. If you complete the puzzle by placing the final symbol on the middle of the board, the achievement will unlock.
