Wild Booster slot by Pragmatic Play is a simple yet potentially rewarding game. You have a plain background and synth music with retro symbols here as the theme and all developers seem to use the retro look at least once. A good example is iSoftBet's Hot Spin Deluxe which I thought a decent slot, then there's Probability Jones' great Red Hot Win Spin slot (my favourite of the genre!) and even Big Time Gaming's Lucky Streak 2 slot has made use of the nostalgic feeling. So can we get a boost for our bankroll here or will it be a wild ride downhill?
Single symbols over 5 reel of 3 rows apiece with 20 pay lines is the structure of this Wild Booster slot. The pays for 5-of-a-kind wins are 30x bet 7's, 15x Lemons, 10x Strawberries, 7.5x Orange, 5x Cherries and finally 4 card suits awarding either 3 or 2.5x for each full line. Wilds can appear on all reels and these have some significance as we'll soon see, with the final symbol also appearing on all reels in the form of a diamond scatter.
Any wins incorporating a Wild can randomly trigger this, whereby the win will be paid at any one of 12 multiplier levels, from 2x, 3x up to 50 and 100x.
You can select from two volatility rounds here.
Mega Boost - 5 free games and a 2x Wild Boost multiplier. You have a meter to fill with 5 scatters, you'll get a head start with how many scatters you triggered the round with. Fill the meter to increase your Wild Boost multiplier to 5x, then your next boost is 10x and finally 100x, whereupon the scatters will not retrigger it. Each meter retrigger will add 5 spins, to be played when your current multiplier's 5 spins are over. There are less scatters on the reels in this round but it has more potential than Ultra Boost.
Ultra Boost - same as above but you start at 3x Wild Boost and the retrigger multipliers are 6x, 12x and finally 50x. You get more scatters on the reels here. Your win total for any spin is capped at 5,000x including the feature yield.
You cannot fault Wild Booster slot with its 96.47% RTP and colourful appearance. It has decent potential both in the base game and bonus with a good win frequency and aside from the background music it's not tiresome to play. The free games are quite exciting though it's disappointing missing retriggers by one scatter which often happens as if you don't get to the top 50 or 100x spins in either feature, you likely won't be getting a big pay. That said, Wilds are plentiful so you'll get some wins and the bonus isn't hard to trigger either. Whether it boosts your balance or not, this isn't a bad game to try...
