The Adventures of Lolo 3 is pretty much the same as the older games in the series, but with a couple of minor changes, the biggest one is that the passwords are way more complicated, so there's no simply swapping some letters around to jump ahead if you get stuck.

But you can see some of the later levels if you get stuck early on.

Go to the password screen and put in the password as all 2s

Now when you walk into Levels 1-3, you'll immediately finish them without having to solve anything!

Then you can start puzzle-solving at Level 4, where the game starts to ramp up its difficulty.

But, since you skipped the first part of the game, you won't be able to proceed past Level 8, that's where your 'preview' ends. Which is just as well, those later puzzles are real brain-benders.
