This Booster slot game though has no Wild Symbol, rendering the Lightning Bolt Scatter as the only special reel element gracing the slot screen. However, it may take some time and quite a number of spins before a 3-symbol Lightning Bolt grouping land as winning combination.
Placing minimum, medium, or maximum stakes does not increase chances of triggering the Bonus Feature. Booster slot players may opt for a low-risk play by betting the 0.01 minimum, which equates to a 0.25 bet covering all paylines. After all, every Bonus Feature is arbitrarily selected.
Yet if by chance a player gets to win the 6,000 coin-win via a Max Bet of 1.00 per line or 25.00 per spin, the value of such windfall could likely compensate for the related costs.
Booster Online Slot: Scatter Symbol
The Lightning Bolt icon emerges as outcome in any reel. When three or more of the symbol are in view, the scattered grouping initiates the loading of the Bonus Game panel.
The longest Lightning Bolt combination occurring after a bonus spin, merits a Scatter Reward. Three, four, or five Lightning Bolt Symbols in any row or reel garners a bonus prize equivalent to 2x, 15x, or 30x the current Total Bet.
Booster Online Slot : Reel Elements
The 3 x 5 slot grid contains traditional Vegas slot machine motifs. In the lead is a Pink Diamond totem, being the highest paying symbol of this game. Two, three, four, or five Diamond images lined up consecutively from the leftmost position of a payline, pay coin wins of 5, 50, 500, or 2,000.
Other Booster symbols start paying on at least three (3) identical images. The Red 7 awards 50, 100, or 500 coin credits on the longest of a standard payline match. The Blue 7 pays less, at 25, 75, or 200 coins, on a 3, 4, or 5 symbol match. A noteworthy observation is that Blue 7 symbols appear at a more frequent rate than the Red 7 Symbol.
Star Symbols are likewise often visible. Three or more Star icons occurring as winning combination, correspondingly award 20, 50, or 150 coin credits. Here, the 3-BAR, 2-BAR, and 1-BAR symbols represent low-win elements. Coin prizes paid for one-of-a-kind BAR combinations range from as low as 5, to as many as 100 coin credits.
Booster is an online slot with an extensive array of prizes to award as random bonus feature. The most lucrative of which includes a round of free games comprising 100 free-spins, and a 6,000-coin instant bonus.
