How to cite

Slot Summary

Rubber ducks racing along a purpose-made river become the subject of Duck River, a live prediction game from 155.io. It belongs to the studio's CCTV Game series and carries its real-world format into a playful racing setting. The central appeal is watching a physical event resolve a prediction, with the duck count taking the place normally occupied by a reel result.

How It Plays

Choose an Under, Over, Range, or Exact prediction for the duck count. These options change the condition your bet needs to satisfy, from crossing a threshold to matching a particular total.

The round resolves through physical duck movement and video analysis. AI or computer vision counts ducks passing the marked zone or finish line, so the result comes from the filmed event rather than a generated reel combination.

How this works

Each simulated spin either misses or returns a win drawn from a log-normal distribution, with the hit rate and spread set by the slot's volatility tier (Medium). The model is calibrated so the average return equals this slot's published RTP (93.50%), with wins capped at its top multiplier (18×).

This is a simplified, parametric model of the game's math — not its real paytable. It exists to make the house edge visible over many sessions, so the numbers above are averages across thousands of runs, never a forecast of one.

This is math, not a prediction. Real sessions vary wildly, and no strategy changes a game's built-in house edge. Play for fun, set limits, and never bet more than you can afford to lose.
