How River Dragons Works
There are 5 reels. The first and last show 3 symbols and the three in the middle show 4, which gives the 3-4-4-4-3 shape. There are no paylines. You win when the same symbol appears on neighboring reels, and this game pays in both directions, from the left side and from the right side.
AGS calls the system PowerXStream. If a winning symbol shows up more than once on the same reel, the prize is multiplied, so stacked symbols matter. The top regular symbol is the game logo, and the koi fish symbols are the ones tied to the features. Bets run from 0.88 to 88 credits per spin.
During Reel Surge the three middle reels grow taller and fill the space above the main game. More symbols on those reels means more possible matches, which is how the count rises from 576 ways to 4,608. That is eight times the number of possible matches in the standard layout.
River Dragons Bonus Features
Reel Surge
When the red and white koi symbols appear, the three middle reels expand upward into the space above the game. That raises the number of ways to win from 576 to 4,608 for the spin.
Free Spins
Koi scatters landing together on the three middle reels trigger the bonus. The base award is 8 free games, and that number is multiplied by how many scatters sit on each reel, up to a top award of 128 free games.
PowerXStream pays
Wins are paid for matching symbols on neighboring reels, in both directions. When a winning symbol appears more than once on a reel, the prize is multiplied, so a screen with stacked matching symbols pays far more than a single line of them.
