If you're a particular fan of the original Sweet 16 Blast! game and would like to try it with a different them then Shelltastic Wins might be for you. Given that the Shelltastic Wins offers nothing new except for a facelift, it does appear to be a somewhat lazy release from the designers at SpinLogic. Shelltastic Wins is a perfectly enjoyable slot with definite potential to pack a punch when you hit the bonus round (which you can of course buy) and if you prefer fishy graphics to candy then maybe this is the slot for you. Play Shelltastic Wins @ Grande Vegas : Platinum Reels : SpinoVerse Bonus Buy cost: x30/x40/x50 stake Game description: Tiger's Luck - Hold & Win is a quality designed, ferocious and featured packed bonus buy slot by Betsoft. Part of the Red Dragon Series of Asian inspired games, Tiger's Luck is a very high volatility slot with 5 reels, 4 rows and 100 paylines. East Asian animals are the stars of the show with the South China tiger taking the lead as the top paying symbol as you'd expect. Joining the menacing tiger is the black bear, alligator and red panda. You'll also find traditional Chinese symbols; the trio of Feng shui coins to bring good luck and wealth and the red lantern.

This can keep happening over and over meaning more and more winnings added to your overall haul. This boldly designed slot comes with an equally bold Bonus Buy feature. Not your typical bonus free spins buy but the option to trigger the Hold & Win feature with the choice of paying for one, two or three re-spins. You'll be paying quite a hefty sum with one re-spin costing x30 your bet, e.g. betting at £/$/€ 2.00 and buying one re-spin will cost you £/$/€ 60.00.

However, you will continue to get re-spins as long as symbols keep landing just like as if you'd not bought the bonus feature, though the amount of re-spins after a symbol/s lands will depend on how many you've bought. While trying out Tiger's Luck - Hold & Win at a stake of 2.00 and having opted to buy the bonus with one re-spin, we automatically started off with the triggering six symbols totalling 45.00 (one with the value of 40 and the rest 1.00). Our one guaranteed re-spin bought in another 1.00 prized symbol along with a red collect all, as more coins had landed this set off our last re-spin and we ending up with a total win of 94.00. Beware, don't get too cocky as you could pay for three re-spins and get a board full of piddly prize amounts... remember, Tiger's Luck is a very high volatility slot and is not for the faint-hearted.

Depending on each casino's individual bet/stake limits, a huge amount can be spent to buy the feature; the highest of which is at a stake of £/$/€ 60.00 for the guaranteed three re-spins, costing a whopping £/$/€ 3000! This is a nail-biting, fun feature especially if you're betting a high stakes - try it out in free play mode to get a feel to see if you think it's worth buying or 'simply' triggering it the standard way. If the tiger's luck is on your side you'll start off with a board of more than six prosperity symbols along with at least one or two with big values attached, then you'll be off to a good start and know that even if no more drop in it won't be a complete disaster!

Sticky wilds add to the intensity of the game with each that land sticking in place for your next two spins. Six or more Chinese prosperity symbols will trigger the Hold & Win bonus feature. This feature works like most Hold & Win bonuses; you'll be set off with three re-spins in the hope of continuing to spin in symbols, each with its individual prize attached and pocketed when the re-spins are used up or the board is filled up.

Popular Bonus Buy slots include "Sweet Bonanza," "Gates of Olympus," and "Dead or Alive 2."

Usually Hold & Win features will offer up a jackpot/s for completely filling the board or landing a jackpot symbol/coin, unfortunately Tiger's Luck does not but instead brings a collect all symbol into the mix. As your re-spins go along, if you land a red prosperity symbol all prizes on the board thus far will be collected. This can keep happening over and over meaning more and more winnings added to your overall haul.
