It was way back on the 19th of March 1932 that the Sydney Harbour Bridge opened, and since that day literally millions of people have made the crossing across that bridge cutting out the once required long detour required to get from one side of the city to the other.

It is in fact a bridge that accommodates trains, vehicles and pedestrians too and as such is a structure that many people do rely on to get out and about in that major Australian city.

To celebrate the opening of that bridge you may fancy playing some Australian themed slot machines today online, and whilst there are more than enough of them for you to get stuck into playing, one slot does stand out.

That is the No Worries slot game which is one of Microgaming’s more unusual 9 optional pay-line slots, on which players can send into play up to 10 coins per pay-line per spin, making a maximum stake spin 90 coins on their chosen coin value setting.

The bonus game which is probably the one part of that slot you will be most interested to learn more about is a set of free spins however you do need to spin in a Boomerang scatter symbol anywhere on all five video reels of the slot to trigger that bonus feature round.

Once triggered you then have to click onto one of the five highlighted parts of the onscreen Boomerang to discover just how many free spins you have been awarded with, and up to 25 free spins can be awarded via that initial picking game on x2 multipliers.

What makes that bonus game very unusual and somewhat exciting to play off is that each time the Beer Can symbol spins in on the end reel the multiplier increases in value by x1, and at the end of the free spins feature round players can opt to collect their winnings take a gamble and be awarded with a randomly selected amount of cash instead or play off their free spins a second time!

The base game jackpot on offer on the No Worries slot is 5000 coins per coin per line wagered.
