Legend of Thanh Giong by Gameplay Interactive uses a 5x3 reel layout with 25 fixed paylines. The slot combines Vietnamese folklore imagery with standard card symbols, including 10, J, Q and K, alongside themed icons such as a Wild horse-head symbol and a Scatter character. A paytable and payline screen explain how winning combinations are formed from the leftmost reel across active lines.
The game includes a free spins feature that is triggered by 3 or more Scatter symbols, awarding 6 free spins. The top banner also shows MINI, MINOR, MAJOR and MEGA booster values, while landing 6 or more boosters activates a respin feature with 3 respins. These mechanics are shown in the demo version, allowing players to understand the rules and practice before playing for real money.
Controls include Spin, Auto Spin and Max Bet options, with balance and bet readouts displayed on the interface. The presentation uses bright colours and decorative Asian-inspired framing, while the information screens outline payout rules, symbol values and the conditions for bonus rounds.
