Thunderbird 3D Slot Review
Features and Bonus Games: 2
Thunderbird is a colorful 3D slot with an Aztec design and offers up to 50 lines of profitable chances. Each bet that you make on those 50 lines can be multiplied by either increasing your bet (up to 10x) or by just waiting for the random 2x multiplier to fall during your normal spin. Not only is the 2x multiplier a way to get 2x your bet per spin, but it is also a wild Thunderbird symbol that will replace any other symbol that falls to form a winning line. The theme has a purple base that is a fine mix of attractive colors that fits well with the Aztec mythology.
During normal spins on the Thunderbird slot, if you can get the three feathered symbol to land 5 times across the board, you will win 1,000 credits which makes this one of the best paying symbols. Don’t forget the 2x multiplier! So if you can get one of those 5 feather symbols to land as a Thunderbird wild symbol, that will bump your winning spin up to 2,000 credits!
The red and brown free spin symbol can appear anywhere from 3-5 times across the entire board to activate the free bonus spin round. If you land 3 across the board, this will give you 10 free spins, if you land 4 symbols, this will give you 20 free spins and if you can land 5 symbols, you will get 50 free spins!
Super Spirit Round
During your free spins previously activated, the same exact symbol as listed above can fall and give you additional free spins. Only during the free spins will see you this symbol yellow and green in color. Getting 3 of these symbols during the free spin bonus round will activate another 5 free spins. Getting 4 of these symbols during the free spin round will activate an additional 20 spins and getting 5 yellow and green symbols will activate another 75 free spins!
When your Super Spirit Round is over, you will be able to finish out your original free spins that were activated with the red and brown symbol. Something else that is pretty cool about this Super Spirit Round is that the first reel will be a locked expanding wild symbol that will stay put during the entire Super Spirit Round!
During the free spins only will you see expanding wilds appearing on reels 1,2,3 or 4. Whenever it is possible to form a winning line, the reels will expand the entire length of the reel for additional win and this excludes scatter plays.
