Mechanics

What we know

Koi fish climb a waterfall and grow as they go. Grow them the whole way and a Must Hit cash prize is guaranteed. That is the pitch of Koi Falls: Flowing Fortune, out 22 October.

A guaranteed prize is an odd thing to build around, because it removes the question most bonus rounds exist to ask. The tension shifts from whether the prize lands to how far the fish get - a different game, and a rarer one.

The figures, all from Fantasma's own page: three builds at 96.23%, 94.4% and 92.74%, high volatility, a 5x3 grid over 243 ways. That ladder is the tightest of the seven Fantasma dates ahead of us, three and a half points end to end, against a catalogue record of twelve.

Absent: any ceiling. Fantasma publishes no maximum win for anything it makes, so the field stays blank rather than borrowed from a reviewer. The stake range printed on the page reads 0.10 to 3,000 euro and is identical on all seven titles, which makes it a platform figure rather than a game one. We leave that out too.
