Got all 35 - I did brute forcing with a few rules: 1) Don't worry about the colors at all, because you can usually shuffle them around to get the right order. 2) If there's a particularly cute combo, it's probably part of the solution. 3) Work out the most likely last few moves, going backwards from a winning position.
