One of Playtech's more recent slot games, the Dolphin Cash game doesn't initially jump out at you but actualy, it's a very playable game. It has the Xtra Win concept which Playtech first introduced in the Pharaoh's Secrets slot game and coupled with the new 'Shifting Wild' thing (explained below) can add up to some nice wins.
As with all the games on freeslots24.7.net, the Dolphin Cash slot has a free spin feature which shows off 12 spins at 3x but it can't be retriggered. There is also a Dolphin Cash bonus when the Bonus symbol symbol lands on reels 1+5 but that's pretty average. Reminiscent of the Smash Bonus on The Incredible Hulk game in terms of trigger but not as good.
The 'shifting wild' is the interesting and innovative central feature of Dolphin Cash. When the wild symbol lands on reel 5, it can shift up or down, the left to reel 4 for a spin, then to 3, 2 and 1. Obviously if during those spins it appears on reel 5 again you get another coming over. Add into the mix that with 'Xtra Win' turned on (costs 50% extra per spin to activate) you then get a wild on the centre reel that shifts up or down and the potential for big wins from the shifting wild are obvious. Especially at 3x in the free spins.
The game itself isn't as volatile as slots such as the similarly themed Great Blue game or the Marvel-themed Iron Man 2 but offers much more opportunity to get something decent than the feature-stuffed The Mummy slot for example. Good game.
