Reversi Puzzle

Pressing a 'tile' will also 'flip' the surrounding 'tiles'.
You can 'Clear' when all tiles turn black.
You can restart by pressing 'Reset' button.
The count drops every time you 'Flip', and you must 'Clear' it before it reaches zero.
This game has three stages: "Rectangle", "Hexagon", and "Cube".
'Clear' each puzzle to get the best score.
