Sonic 7s is a new slots game released by Microgaming in June 2011. A 5-reel, 9 pay-line machine, the Sonic 7s offers countless extra features which add great value to the game. There are generous multipliers, power spin rounds and massive jackpots. Players can earn up to 200k coins by hitting the Sonic 7s jackpot. The coin sizes accepted by the game range from 0.01 to 0.5. Of course, in order to give yourself the best chance to hit the max jackpot, you should always play maximum coins. Also: the more pay-lines you wager on, the more you will stand to win. The top prize on the machine is a staggering $50k. The symbols used by the game are the usual ones: cherries, bar symbols, bells, the number 7.
The general color scheme is steely blue/grey and the graphics are crisp and clean. The Sonic symbol is the wild symbol. It acts as a substitute for every other symbol, except for the scatter ones. When 5 such wild symbols line up on an active pay-line, a 100k coins jackpot is won. The wild symbols act as multipliers during the power spin mode. These wild multipliers can increase one’s power spin winnings by as much as 8x. The power spin round can only be triggered when a 3x side bet is enabled.
In order to trigger the scatter wins, one needs to land at least 2 scatter symbols anywhere on the reels. If all 5 scatter symbols show up on the reels, the maximum winnings hit the 13,500 coins mark. Winning lines are counted from the left to the right, with the exception of the scatter symbols, which can land just about everywhere. The Power Spins Sonic 7s slot was considered a crowd favorite even before it was launched and it certainly did not disappoint.
