Sonic Boom is a classic slot with an aviation theme. The fighter aircraft portrayed on one of the symbols and under the reels looks like a legendary F-16 Falcon breaking the sound barrier with a loud boom. As for all other aspects, the slot is a typical three-reeler ginned up with a wild symbol. There is also nothing new about the betting system that has two settings in the slot: the number of coins (one or two) and a coin value ($0.25 to $5). As the gameplay involves a single line across the center of the reels, the minimum and maximum bets are $0.50 and $10.

The images displayed on the reels are cherries, bar variations, F-16 and the Logo. The paytable is split into two columns showing combinations and winnings for a one- and two-coin bet. Cherries and bars act in a way that is consistent with their traditional behavior in most 3-reel slots: cherries pay when 1, 2 or 3 appear on the line, and bars are able to complete mixed combinations, e.g., 1-bar/2-bar/2-bar. Sure, the best outcome is when you get three matching symbols – in this case you get x20 times a bet for cherries and up to x60 for triple bars.

A Fighting Falcon is the central themed symbol in the slot but not the key moneymaker. Getting three of them along the line pays x120 or $1200 at max. The jackpot symbol in the game is the Sonic Boom logo and it pays back x1200 per one coin wagered. If you place the maximum two coins, you get a x2500 payback for that combination, which translates into a gorgeous $12,500 so it is always better to put two coins into play to maximize the payback percentage and hit the jackpot.

Bonus features

There is only one bonus feature in the slot; this is a wild symbol represented by the Logo. First, it substitutes for other symbols and, second, it multiplies payouts by x2 or x4 when one or two wilds take part in a combination.
