Thunder Cash Online Slot: Experience Huge Bonus Wins via Free Games with Locking Wilds
Thunder Cash, a popular land-based slot game by Ainsworth, finally arrives as an online video slot at web-based casinos supported by the NYX/NextGen Gaming platform. The game sports a typical Vegas-style theme, built with 20 paylines in a standard 5-reel grid. The appearance of Wild Symbols in the center reels are the only features to count on as win-boosting elements.
Although seemingly a run-of-the-mill type of slot game, players though could bank on those Wilds during free games. Any Wild that comes into view locks in place, until completion of the bonus round. The probability of landing on huge amounts of bonus wins is high, as the bonus game center-reels are rich with Wild Symbols. The great news is that the Scatter Symbols activating the bonus round are not hard to come by either, allowing players to trigger, and even retrigger the free games over and over again.

The Number 7 is the highest paying icon; awarding cash rewards on as few as two (2) matching Number 7s. Two, three, four, or five 7 Symbols lining up in a payline starting from the first reel, respectively award a cash prize equivalent to 5x, 20x, 100x, or 500x the amount wagered per line. Other images include a sparkling Blue Diamond, s Stack of Gold Chips, a pair of Dice, and the usual A, K, Q, J, 10 and 9 card symbols.

The Wild icon appears as a tile with a Lightning Bolt image. This symbol though emerges only in Reels 2, 3, and/ or 4, whilst usable as alternative component. That being the case, one-of-a-kind symbols that align with a Wild in the same payline, can easily complete a grouping or expand into the longest, highest-paying arrangement.
In the Free-Spins Round, every Lightning Bolt Wilds that appears in any of the three (3) center reels, lock in place.

The Thunder Cash Logo represents the Scatter Symbol capable of activating the Free-Spins Bonus Round. Five, four, or three Logo icons spread throughout the slot screen, initiate the loading of the bonus game reels. In addition to the bonus spins awarded, cash rewards equivalent to 5x, 20x, or 100x the Total Bet triggering the bonus feature. Total Bet being the amount wagered per line multiplied by 20 paylines.
Thunder Cash Game Info states that the Bonus Reels are configured with as many as 15 Scatter Symbols, making it possible for players to land on another winning Scatter combination.
Thunder Cash Online Slot: Free-Spins Bonus Round
Each Bonus Round activated awards eight (8) bet-free spins. If another set of three, four, or five Thunder Cash Logo icons occurs as outcome of a bonus spin, five (5) additional free-spins will extend the round. Since the Bonus Reels are configured with an abundance of Logo Symbols, retriggering the round several times over is a likely possibility. According to Game Info, the most number of free-spins that can be played in a single bonus session is up to 600.
Here, Reels 2, 3, and 4 retain all Lightning Bolt Wilds that appear, holding them in place until completion of the round, and even through Bonus Round extensions.
