No Worries

The No Worries symbol is the wild, and it will substitute for all the missing symbols, except the Boomerang and the Tasmanian devil, which are the 2 scatters.
 
5 Boomerangs scattered anywhere on the reels will activate the Boomerang bonus game. Select symbols on the Boomerang to reveal number of free spins won and the multipliers. Boomerangs come in many shapes and sizes depending on their geographic or tribal origins and intended function. Returning boomerangs were used as decoy birds of prey, thrown above long grass in order to frighten game birds into flight into waiting nets.
 
After the free spin bonus game, the Pick a Prize bonus game starts. Choose one of three prizes. Forfeit the winnings of the free spins, take your winnings, or take a mystery prize. The mystery prize will be a multiplier of between 2 and 150 times the triggering bet. After each win you will have the opportunity to play the additional bonus game. This game is entirely optional.
 
Typical Australian animal symbols in this slot are; the Tasmanian devil, which was declared to be endangered since May 2009, the Platypus, the only mammal that lay eggs instead of giving birth; the Wombat, since 2005 October 22 associated with an aboriginal holiday, near the beginning of Spring planting season; the Kookaburra, a large to very large kingfisher best known for echoing human laughter; the Wallaby, better known as “joeys”; and the Koala, broadly similar to the wombat, but has a thicker coat, much larger ear, and longer limbs.
 
This is a great fun game from Microgaming with excellent graphics and side effects, and payouts that seem to be quite regular.
