The game was developed by SUNFOX Games, a Playtech company, and right from the intro it's clear we're dealing with an excellent game. The theme is not so much about bowling as it is about the 50s rockabilly period, which is an excellent addition to the theme. The board is a large one, 5x4, and it has 40 fixed paylines. Interestingly, you can play the game for as little as €0.10, while the maximum bet is whopping €500. Main game and paytable The paytable is pretty decent, as the two main characters pay 800 and 400 coins respectively for five-of-a-kind, which is 20x and 10x your total bet. The Pink Cadillac symbol belongs in the same range with a 300 coin prize, while Bowling Shoes and Fast Food are closer to card symbols that pay from 120 to 40 coins. There are ten symbols total, plus a Wild and a Scatter. Bonus features Above the middle three reels you'll see some bowling pins. There are 10 spots above each reel and you'll fill them up with bowling pins by landing Scatters on the respective reel, and each Scatter will add one, two or three bowling pins. When you collect all 10, you trigger the feature. The bowling ball will hit the pins to decide how many stacked Wilds are awarded on that reel during the 10-Pin Respins feature that will follow. The 10-Pin Respins feature is played with cascading reels, as winning symbols are removed and replaced by new symbols that fall from above. Respins end when there are no more stacked Wilds left. When you land three or more Scatters you'll get to choose among three features. High Wins Free Games will give 10, 15 or 25 free spins for three, four or five Scatters respectively, and only the high-win symbols – all symbols except for card symbols – can land on the reels. Multiplier Free Games will give 10, 15 or 30 free spins, and Wilds will have a multiplier on them. Finally, Kingpin Cash Bonus will give you two attempts as you throw the bowling ball at the pins, and you get up to 100x total bet on the first try and a win multiplier of up to x25 on the second try. The more Scatters you get the more chances you have to win big, so it could make sense to choose this feature and not the others when you land all five Scatters. It's almost certain the High Wins Free Games is the worst choice as only three of those five high-win symbols can produce big wins. In any case, your choice will matter. Bowling Frenzy Slots RTP Theoretical return to player (RTP) is 95.60%, which is actually ok, especially as this game plays well and has tons of bonus features that can award you a huge win anytime. It's still very much a classic slot as you play the base game in hope of triggering the bonus features, and it's an excellent mix. The game does have higher variance, and it's meant to played in longer playing sessions. Conclusion It's always good to have a game in which your choices as a player make a difference, and this is the case when you land three or more Scatters. If you choose the most rewarding feature you'll be winning more, so give it a try. You can play this game for real money at Playtech online casinos, and you definitely should play it as it's one of the better games released in the first half of 2019.
