Duck River
Eight plastic ducks, one real lazy river, and about two minutes of nobody knowing who wins. Duck River isn't a graphic — it's a physical water track with rocks, rapids and a crocodile prop in the way. A camera watches the whole thing and an AI reads the finishing order once the ducks bob past the line. No shuffle, no server seed. It carries the tallest ceiling in the 155.io line-up at 289×, and it runs on its own home, ducks.io.
How a round plays out
Every couple of minutes the eight ducks get dropped onto the top of the water track, and from there it's current, not code, that decides the order. Here's the shape of a single race.
Eight ducks go in
The board opens and all 8 numbered ducks drop onto the lazy river together. Betting is live while the water carries them — this is your window to back a market before the run locks.
The river does its thing
Rocks nudge one duck wide, a set of rapids flings another forward, and the crocodile prop snags a leader. There is no RNG deciding any of it — the winner is whichever duck the current actually pushes across first.
The camera reads the finish
As the ducks bob past the line, the camera and its tracking model log the finishing order. That order settles the round: Pick Winner, Any Order or Exact Order pays out on whatever the water produced.
Three ways to back the race
Same eight ducks, three levels of precision. The tighter you call the finish, the more it pays — and the less often it lands. That trade-off is the whole game.
Name the single duck that crosses the line first. One duck out of eight — the shortest odds on the board, so it lands most often and pays the least.
Smallest of the threeCall the ducks that finish in the frame without saying which places they take. A wider net than a straight winner, a middle payout for a middle risk.
Sits between the twoName the finishing order on the nose — first, second, third and beyond, in sequence. The longest shot on the river and the one holding the 289× ceiling.

Exact Order

Be honest with yourself about Exact Order. Getting eight ducks in the right sequence past a crocodile is a genuine long shot, which is exactly why it holds the 289× ceiling — the biggest in the 155.io line-up. Stake it like the rare hit it is. If you put £5 on a winner most rounds, an Exact Order slip is a £1 flutter you can shrug off, not the bet you lean the whole session on.
Published RTP sits between 88.72% and 94.24%. Exact multipliers are set by the operator running the feed.
