Duck River Review: 155.io Duck Counting Game
Duck River is not a classic slot. You bet on how many rubber ducks an AI counts in one lane of a river course filmed by cameras. This review covers the rules, payouts, RTP, max win, demo and availability.
6.1out of 10
Quick verdict: the same bets and payouts as Rush Hour, played on a staged duck course instead of a public scene. It adds no new feature, and its sources contradict each other on release and availability. It suits players who like the theme.

Duck River review: what kind of game is it?
Duck River is a round-based prediction game from the studio 155.io. It is listed among the studio's CCTV Games, the family that includes Rush Hour and Snow Run. It has no reels, no paylines and no symbols. Players may search for it as a "Duck River slot", but it is not one.
The setting is the main difference. Rush Hour and Snow Run watch public places. Duck River, according to a catalog description, films a real, purpose-built river course. You count rubber ducks in one lane. The game picks a level at random each round. The sources do not say what a level changes.
This page follows the provider documentation first, then catalog and press entries. We have not run test sessions, and we have not seen the game's own rules screen. Where sources disagree, we show both numbers.

"Per docs" means the provider documentation at docs.155.io, read in October 2026. The docs say Duck River, Rush Hour and Snow Run share the same base RTP and maximums. We have not checked Duck River's own rules screen, so confirm every number at your casino.
Duck River rules: how a round works
The round follows the CCTV Game idea. You see a camera view and two boundary numbers. A timer runs while you place bets. When it ends, bets lock. The AI counts the ducks in the lane, and every bet settles on that final count.
We have not confirmed the phase lengths for Duck River, and we do not copy the Rush Hour timing to it. Our how to play guide walks through a round in steps.
A staged course, not a public scene
This is where Duck River departs from its siblings. A road or a ski slope exists whether or not a game films it. A purpose-built course exists for the game. That makes it closer to a produced event with a camera than to a window on the world.
It also raises a fair question about how much the footage decides. We found no explanation from the provider on how the random level and the duck flow connect to the result. So we do not claim that the ducks alone decide it. What we can say is that the game shows footage, an AI counts, and every bet pays at a fixed multiplier.
The AI count is final. If two ducks overlap or one leaves the lane, the AI may count differently than you do. Counting along on your own screen proves nothing about the result.
Frame reserved: Duck River betting screen with the river camera, two boundary numbers and bet buttons. No game screenshots have been captured yet.
Duck River bets and payouts
Duck River has no symbols, so it has no symbol paytable. The list of bets is the closest thing. Each bet pays a fixed multiplier of your stake. A 3x multiplier means the game returns three times your bet in total, stake included.
| Bet | You win when the AI count is | Multiplier | Returns on $0.20 | Returns on $1 | Implied chance |
|---|---|---|---|---|---|
| Under | below the lower number | 3x | $0.60 | $3.00 | 30% |
| Range | between the two numbers | 2.25x | $0.45 | $2.25 | 40% |
| Over | above the upper number | 3.6x | $0.72 | $3.60 | 25% |
| Exact | equal to either number | 18x | $3.60 | $18.00 | 5% |
Multipliers: provider documentation (docs.155.io), October 2026, and a catalog entry that lists the same four. "Implied chance" is our own arithmetic, the 90% base RTP divided by the multiplier. The provider does not publish these chances. Returns include the stake and ignore any Lightning boost.
The four bets cover every possible count, and their implied chances add up to 100%. Range pays the least because it is the most likely. Exact pays the most because it is the least likely.
Round example: boundaries 6 and 9
The screen shows 6 and 9. A $1 bet on Range wins if the count is 7 or 8. It returns $2.25, a profit of $1.25. A $1 bet on Under wins at 5 or fewer and returns $3. Over wins at 10 or more and returns $3.60. Exact wins at 6 or 9 and returns $18. The boundary numbers are an illustration. The multipliers come from the docs.
You can place several bets in one round. Under, Range and Over together lose only on the two boundary counts, but their combined payout is lower than the combined stake. No mix of bets removes the house edge.
Duck River features
The docs give Duck River the same payout figures as its siblings, and they name one boost. Extras that Rush Hour has, such as streak multipliers or player levels, are not confirmed for this title. We list only what a source states.
Lightning boost
The docs give a maximum of 90x for Duck River with a Lightning boost, against 36x without it. They do not give the boost sizes or the odds for this game, so we print none. Treat the 90x as a rare event, not a target.
Round example
A boost hits Exact in a round and your $1 Exact bet wins. Without the boost it returns $18. At the 90x maximum it can return up to $90. At $0.20 the same bet returns $3.60 or up to $18.
Auto-bet
A page about Duck River describes an auto-bet that repeats the same bet until you stop it. Availability depends on the casino and on local law, since some regulated markets restrict autoplay. Repeating a bet fast makes spending easy to lose track of, so set a limit before you turn it on.
What the game does not have
No bonus buy, free spins, ante bet, gamble feature or jackpot appear in the sources we read. Casino bonuses that include free spins are the casino's offer, not a feature of this game.

Try Duck RiverDuck River RTP, volatility and max win
RTP: 90% or 93.5%?
The provider docs (game payouts page, read October 2026) give a 90% base RTP for Duck River. With Lightning boosts the effective RTP is 90% to 92.16%. A 90% base RTP means a 10% house edge.
Slotcatalog and several reviews quote 91.5% to 93.5% for the three CCTV Games. These entries look like copies of one template. We use the provider's number and flag the gap. The game's info screen at your casino settles it. Our RTP guide covers the sources in detail.
What 90% means in money
RTP is a long-run average across all players, not a promise for one session. Out of $1,000 staked in $1 rounds, the expected return is $900. At $0.20 a round, $200 staked returns $180 on average. A single session can end far above or far below that.
Volatility
Neither the provider nor the catalog publishes a volatility rating, so we print none as a fact. Our own reading follows from the table. Range has an implied chance near 40% and pays 2.25x, so wins come often and stay small. Exact has an implied chance near 5% and pays 18x, so it goes quiet for long stretches.
Max win in money
The docs say 36x, and 90x with a Lightning boost. Reviews often say 18x, which matches the plain Exact payout. Here is what each figure means on a $0.20 and a $1 bet.
| Figure | Where it comes from | At $0.20 | At $1 |
|---|---|---|---|
| 18x | Plain Exact bet; reviews often call it the max | $3.60 | $18 |
| 36x | Base maximum, per the docs | $7.20 | $36 |
| 90x | With a Lightning boost, per the docs | $18 | $90 |
Totals include the stake. Bet limits are set by each casino, so the largest payout you can reach depends on your casino's maximum bet. A catalog lists a bet range for Duck River, but limits are set by the operator, so we do not print it.
Our view: the course changes the story, not the odds
Duck River has the same published math as Rush Hour and Snow Run. Same four bets, same multipliers, same 90% base RTP per the docs. The staged course is therefore a matter of theme. We find it the least convincing of the three as a "window on the world", because a course built for the game is not a street or a mountain.
That is a judgment about the concept, not about fairness. A staged course may even be easier to run reliably. But the appeal of the format is watching something you did not arrange, and Duck River gives some of that up. This is why we score its gameplay below the road and slope games, at 6.5 against 7.0 and 7.5.
The sources are also the least consistent of the three. One catalog page says the game is available in 18 countries and not available in Germany. The release date is marked approximate. Nobody states whether Duck River replaced Ducks.io. A reader who cares about checking facts has more to verify here, and the final score reflects that.
Duck River on mobile
Rush Hour is an HTML5 game that runs in a phone browser. The studio builds its CCTV Games the same way, so Duck River likely does too. No source we read confirms it for this title. No official Duck River app is known. A casino may offer its own app that includes the game.
The game depends on a live video feed, so a weak connection can stall it. We have not checked the phone screen, so we make no claims about button size, layout or load time.
Frame reserved: Duck River in a phone browser, portrait. No phone screen has been captured yet.
Duck River demo: how to try it for free
We found no standalone public Duck River demo. Some casinos offer a fun mode with play money, but that depends on the operator and your country. One catalog page says the demo is currently unavailable while showing a demo image. Those two things do not fit together, so do not rely on the note.
A demo uses the same rules as the real game, with play money. It shows the pace of rounds and the layout. It does not teach you to win, since no skill beats the count. We do not embed a demo on this site. See our demo guide for what to check first.

Games like Duck River
If you like betting on a count, the first two games below are the closest. Both belong to the same CCTV Game format from 155.io.
Rush Hour
Similar: the same four bets and the same docs figures. Different: you count vehicles on a live road scene, and the sources describe more extras.
Snow Run
Similar: the same bets and payouts per the docs. Different: you count skiers and snowboarders on slope cameras.
Ducks.io
Similar: also from 155.io, with a duck theme. Different: a plastic-duck race where you bet on the winner, not on a count. Do not mix it up with Duck River.
Rolling Dunes
Similar: a round-based 155.io game. Different: a marble race with a max win of 288.96x per the docs. It is not a CCTV Game, although some press calls it one.

Duck River pros and cons
Pros
- Simple rules: four bets that cover every outcome.
- The same published payouts as Rush Hour, so the odds are easy to read.
- A light theme that suits short sessions.
- No bonus buy or ante bet that could push you to spend more.
- Low entry stakes where a casino allows small bets.
Cons
- The top payout is modest: 36x, or 90x on a boost.
- The 90% base RTP means a 10% house edge, and sources disagree on it.
- It adds no feature that Rush Hour lacks.
- The release date and the country list are unclear in the sources.
- A staged course feels less like live footage than a public scene.
- The name is easy to confuse with Ducks.io, a different game.
Is Duck River worth playing? Verdict and scores
Duck River is a quick game with simple rules and a light theme. If you want short sessions at small stakes and like ducks, it fits. If you want a bonus round or a large top payout, look elsewhere. The house edge is the same on every bet, so no market is smarter than another.
Our scores come from four criteria. They rest on provider documents and published reviews, not on test sessions, and the site owner approved them. "Design and sound" is the weakest-grounded score, since we have not seen the screens or heard the sound.
| Criterion | Score | Bar | Why |
|---|---|---|---|
| Bonus feature | 6.0 | A Lightning boost per the docs, but no free spins or bonus buy | |
| Win potential | 5.5 | 36x per the docs, 90x on a boost | |
| Gameplay | 6.5 | Simple bets; a staged course is less live | |
| Design and sound | 6.5 | Clear concept; not seen by us | |
| Overall | 6.1 | Average of the four, 6.125 rounded |
Scores can change once we have checked the game screens. We recheck each review every three months.
