Rival Gaming’s new 5-reel, 50-line slot, Thunderbird, is inspired by Native American cultures. The design features ornate native art, four-tiered totem poles, traditional drums and animal carvings, including a carving of the powerful thunderbird. According to Native American mythology, the thunderbird is a colossal creature with a big-enough wingspan to create thunder. The bird certainly triggers some high-paying storms in the 5-reel slot game.
The thunderbird is the central figure in the Rival game. It primarily serves as a wild and multiplier, and becomes increasingly valuable in Free Spins Mode and the Super Spirit Bonus Round. To trigger Free Spins Mode, players must land at least three Free Spin icons (the Red Salmon symbol), and depending on how many are landed, you get one of three free spin clusters: 10 free spins (for three Salmon), 20 free spins (for four Salmon), and 50 free spins (for five Salmon).
Once in Free Spins Mode, the thunderbird transforms from a standard wild to an expanding wild. It fills Reels No. 1 to 4 when doing so creates a winning line. The only symbol the wild doesn’t substitute for is the scatter symbol. But fortunately, you get a second scatter symbol in Free Spins Mode: A Gold Salmon scatter. As is the case with most Rival scatter symbols, the Gold Salmon scatter icons have stars on the top-right corner. Three of them trigger the game’s Super Spirit Bonus Round.
The thunderbird is most powerful (and helpful) during the bonus round. At this point, the mood of the game alters; a thunderstorm replaces the bright moon in the backdrop, and lightning bolts start to soar. Charged with electrical currents, the thunderbird zaps Reel No. 1, making the entire thing wild for the five spins that make up the bonus round. This is a great opportunity to bump up the bankroll.
Thunderbird is straightforward enough for beginners and also dynamic enough for seasoned players. The game uses standard features – wilds, scatters, multipliers – in a way that creates a refreshing twist on traditional slot gameplay, making it a must-spin for all slots enthusiasts.
