Bonus slot machine is a game that has 5 virtual wheels. Players spin the wheels that contain symbols. Each wheel has a few special symbols that will trigger a bonus game. Bonus games are typically entertaining and offer special prizes. Bonus slot machines are an upgrade from the old school three wheel machines made decades ago. Some players still prefer the older models but most find the bonus games much more entertaining and rewarding. Most bonuses offer free spins which can be redundant for a home owner. Free spins are welcome in a casino because that is essentially free money. Homeowners play for free so free spins are not that inspiring.
