These are by far the best recent Nintendo Entertainment System games available today! Each game is completely different from the others, only related in theme. Each game is better than the last.
Gruniożerca 3 is my favorite NES game. The puzzles are smart, varied, and not too hard. The progression is smooth, although, some of the final boards to seem to jump in difficulty. The simple "password" save is cute and easy to remember. Well worth the price just for this one game.
