I have been stuck on 2005 for days and I just (SURPRISNGLY) completed it with the 12 moves and 3 starting boosters. I may have woken my partner while he was sleeping because I was that excited to have done it (oh well). But IT CAN BE DONE with 12 moves!!!
It is not supposed to be 50. Surprisingly, you CAN do it with 12. It took me many tries but I did it. I used the boosters at the beginning and it worked just fine with 12. These guys won’t give you anything that can’t be done! It just may take longer than other levels.
