Slots results are random. Where the symbols land is entirely dictated by the RNG. Which goes to say that there is nothing that you can do to influence the outcome of any round, or more specifically in answering this question, increase your winning odds when playing Lab of Lunacy.
What you can do, however, is increase your odds of triggering free spins with the various bonus buy options. In fact, with some of them, for a relatively high fee mind you, you can guarantee activation of the bonus round. This is not technically a win, but it can launch you into more free spins and more significant prize sums, especially with the multipliers.
