Dig into the bonuses and JiGong starts to stand out. A progressive jackpot adds a wildcard payout that can land at any time. Look out for scatter symbols that unlock free spins and extra bonus rounds. Its medium high variance balances steady wins with the odd larger payout. All told, it's a solid entry in the SimplePlay catalogue.
At 95.48%, the RTP is slightly below the industry average of ~96%. While this is typical for many popular slots, players should be aware of the slightly lower theoretical return.
Medium-high volatility means wins come less frequently but tend to be larger when they hit. Players should be prepared for dry spells between bigger wins, requiring a moderate bankroll.
About 1 in 3 spins results in a win. This is a moderate hit frequency that balances win frequency with payout size.
JiGong features scatter symbols that can trigger free spins rounds. Landing the required number of scatter symbols anywhere on the reels activates the free spins feature, giving you extra chances to win without additional bets. During free spins, special modifiers may apply to boost your winning potential.
JiGong features a progressive jackpot that grows with every spin placed by players across the network. The jackpot can be triggered randomly or through a special bonus feature, offering the chance to win a life-changing sum. The jackpot continues to grow until one lucky player hits the winning combination.
