Oh no! I'm very sorry about that, I'm not sure what causes it. If you hold down the keys "E" and "Y" while pressing New Game, you can generate a generic 90%-complete save file with 2/3 puzzles solved.
For puzzle 3, your goal is to cycle 5 cards and play 61. Start by playing 21 on the left and discarding 13. Then, place 71 on the right and factor 24. From there, do what you can to play as many cycle cards as possible. Don't worry about which tiles you burn with 76, it won't matter.
