Match 3 is a very complicated genre. Preliminary estimates have placed it at 3 difficult: one above match 2, but still one below match 4. Because of this aforementioned difficulty many strategies have been put in place to make it easier to have sex with drunk, barely consenting bundles of pixels.
Cross method (For beginners)
By attempting to sort the gems into a cross you can get the best possible amount of gems in a single move. This method is not however guaranteed to work.
Applied topological method (For pure mathematicians only)
The match three field can be thought of as a graph of weighted nodes. By applying a topological structure that fits the weighted node graph you can find the vertices that can lead to the highest payout with the least possible cost in potential node value (Proof left as an exercise for the reader). With this method you can easily access the sweet feline pussy (Get it, it's bestiality and you're a sick person, so it's funny).
HunieCam Studio's gameplay never changes, however, your understanding of its mechanics and ability to apply them makes up for this static, unchanging principle.
As there is no objective way to 'win' at HunieCam Studio, players often consider acquisition of the Diamond Dick Trophy to be the default victory condition. The common way for players to 'win' is to replay the game over and over, slowly but surely honing tiny micro-adjustments, increasing their total fan count with each incarnation, or 'run'.
Experimentation with different sets of girls, fetishes and items is also encouraged by the replayability aspect.
Advertisements - Your main (and best) method of acquiring fans. With each purchased advertisement, the cost (and fan yield) of future advertisements increases. Purchasing all ads each day is inadvisable, as there is a sort of bell-curve you must keep up with as to serve your core fetishes, and purchasing superfluous advertisements that will not even affect your current fetishes will serve only to jack up the pricing for future advertisements.
Stress - It is advisable to send girls to the Day Spa after acquiring ~50% stress, to offset as much relaxation time as possible to throw her back into the fray.
