I never completed a crossword puzzle in my life, but I have become addicted to this one. It is completely intuitive and its pattern recognition can't be beat. Its L/R buttons move through the puzzle initially horizontally and on a second pass vertically. I suspect that is the way crossword aficionados operate. As a neophyte. I usually go through the puzzle a couple times this way and then switch to completing areas.I spend one to two hours each evening unwinding with this game.
