There are 3,000 coins available on The Love Boat, which you get when you rotate 5 Wild symbols to any active payline. Free spins are caused by scattering, which are very special because they not only have a variety of small sub-features, but they also get more victories than you usually do in the base game.
The showdown bonus is really simple, matching the handsome guy and the chick to give yourself some free cash and multipliers up to x5.
