Here are our top five picks among the best and most popular online slots that will make you happy this summer!

1. Jewell Action: made by Novomatic’s sub company Astra, this is a 3×3 reel slot machine with 10 paylines laid out in all sorts of unique ways. Moreover, Jewel Action features a mystery chest prize and a gem streak free spin where you are guaranteed to win several times. The latter is triggered if 3 key symbols appear during the same spin. The former is awarded when 3 scatter chests appear anywhere on the reels. There is also a jester symbol and a wild symbol, just to increase your chances of winning spins.
2. Copy Cats: 5 reels and 25 pay-lines video slot powered by Net Entertainment software. This is a bright, cat themed slot with amusing cartoonish graphics and sound effects. There are four types of cat symbols: a red, a pink, a blue and a golden cat (the Wild symbol). A full stack of any of the cat symbols (3 on a reel) or a Stacked Wild on reel 1 activates the Copy Cats feature, where all cat symbols on reels 2, 3, 4 and 5 turn into the same cat symbol as the one that triggered the feature. In addition, you can activate 10 free spins if you get 3 Bonus symbols on reels 1, 3 and 5.
3. Satoshi’s Secret: a beautifully designed video slot with 6 reels and 20 pay-lines powered by Endorphina. 4 or more Bitcoin symbols appearing on reels 2, 3, 4 and 5 trigger the Trading bonus feature, awarding the player with x30 total bets that can be collected or used for trading during the Bonus Game that follows. In this game, you trade currencies until you decide that the market has reached it’s top. Another bonus game is activated when symbols QWERTY appear on the reels in the proper alignment. In this game, you get to hack bank accounts before security alarm interrupts you. With every win, you get yet another chance to increase your winnings in the Risk Game, where you gamble your winnings to beat dealer’s card by choosing one of four closed cards. Innovative gameplay, complex system of awards and frequent bonuses in this Bitcoin-themed game guarantee excitement!
4. Spina Colada: 5 reel, 25 payline slot powered by Yggdrasil. This is a gorgeously designed slot with a true summer theme. Frozen feature offers more chances for bigger wins.
