Thunderstruck was one of Microgaming's most popular video slots ever, and it drastically changed how all software companies thought about slots. Their Summertime video slot is a similar game with a similar set of features because it came out following Thunderstruck's success and how that single game shook the industry. This game has a light-hearted tone and a theme based on classic slots with bells, lucky sevens, cherries, diamonds and other typical classic slot symbols. This game has a medium volatility with a large jackpot and a chance to take down an extremely valuable bonus feature.

The format of Summertime is designed to make it really easy to pick out the bet sizes that you want. It has nine paylines with five reels, and the coins range from a super-low $0.01 each up to a moderate $1.00 each. What gives this game so many options when it comes to bet sizes is the ability to bet up to five coins on each individual payline. This means that you can bet anywhere from $0.09 to $45 per spin with several options between. You won't have any trouble finding a bet size that fits your bankroll perfectly with Summertime.

The Summertime symbol is wild in this game, and five of them on an activated payline will get you the top 10,000x jackpot on top of whatever other payouts you get because of the multiple wilds on the screen. Four wilds gets you a 2,000x secondary jackpot, and it's impressive to consider that this game's second-highest payout is twice as large as the top jackpot for many games. You can win anywhere from 2x to 500x your entire bet with the scatter payouts, and that's the equivalent of a 4,500x line bet prize for five scatters.

Three or more of the scatters trigger what was once one of the biggest and baddest bonus features that the video slot world had ever seen. You get 15 free spins, and all of your wins on those free spins are multiplied by a factor of three. That means that the top jackpot becomes an enormous 30,000x for getting five wild symbols lined up on the same payline. Needless to say, that's an absolutely huge win, and it's one of the reasons why Summertime will have you coming back for more over and over again. Overall, it's a great slot that has a fun theme and excellent prizes.
