Copperkoi Fernery

A rock waterfall spills into the koi pool beneath arching tree ferns. Winning pictures are swept off the reels, newcomers fall into their places, and every further fall in the chain is worth more than the one before.

About this world

Copperkoi Fernery

Copperkoi Fernery is the boldest room in the glasshouse, with the swings to match. Every win sweeps its pictures off the reels and lets new ones splash down from above, so one spin can run on for several falls while the multiplier rises towards five times. The Bronze Turtle and the Copper Koi carry most of the value, which means dry spells can stretch out between the splashes. Three Rock Falls trigger ten free spins where each chained win is also doubled, four trigger fifteen and five trigger twenty-five.

Waterfall Chain. Pictures on a winning line are swept away, those above slide down and new ones fall from the top; the first result pays x1, the second fall x2, the third x3 and each one after x5. Rock Falls scatters always stay.

The honest part

Coins of the glasshouse, never money

All play in this glasshouse uses free virtual coins. Real-money gambling is absent, no win has real-world value, and there are no in-app purchases. Outcomes are set by a random number generator, and no past spin influences the next.

Measured by running this page's own engine for 5,000,000 spins: coin RTP 97.0%, hit frequency 34.1%, free spins about once in 132 spins, a win of 10x your stake or more about once in 80 spins. Coin figures only — no money is staked or returned.

How to play

Copperkoi Fernery in three steps

1

Sign in, take the fern-shaded path to the koi pool and pick a stake.

2

Spin. Winning pictures are swept away, the rest settle lower and new ones splash in; the opening result pays x1, the next fall x2, the third x3 and all later falls x5.

3

Three Rock Falls give ten free spins with doubled wins stacked on the chain, while four bring fifteen and a full five bring twenty-five.

Who it suits

Steady-nerved players who will happily wait out a lull in exchange for the odd chain that refuses to stop falling.

What to expect

The biggest ups and downs under the glass. With the turtle and the koi holding so much of the value, rewards tend to arrive in sudden splashes, not a gentle drizzle.

Questions

About Copperkoi Fernery

No. The scatters hold their ground while winning line pictures are cleared from around them.

Wins in the free round count double, and the waterfall chain multiplier is applied on top as each new fall lands.

It is designed to be swingy. A larger share of value lives with the rare pictures, and no win is ever held back or rationed.
