All 1050 puzzles from the original ("Classic") game have been included, but arranged a bit differently. The puzzles have been grouped into puzzle packs under the 'Puzzle Packs' menu. The original game's main puzzles are in the "Classic" pack. The rest are included from the manual for the original game and have been grouped by difficulty, with "Six Move Puzzles" being the easiest and "Fifteen Move Puzzles" being the hardest. Beginners are advised to attempt the Classic pack before trying the others. Note that you may switch from one puzzle pack to another and not lose the progress you have made. You may also re-play any puzzle you have already solved by choosing it from the 'Levels' menu. The Classic pack features 50 puzzles, and the others host 100 each.
When you press a button, you turn it off or on, just like a light switch. Additionally, any button above, below, or beside the button you have pushed is also switched on or off.
