Random multipliers, up to x10 extra
As the wheel starts to turn, the game can drop extra multipliers onto
individual sectors. Values run from x2 to x10. If that
sector then wins, the sector's own payout is multiplied by
the extra. So a grey-fish x2 carrying an x5 pays x10. Bonus sectors work
the same way.
That's the important bit: it applies to bonus sectors as well as
fish sectors. That's how a round can theoretically go past the
advertised maximum:
x10,000
A Mega Catch hitting its x1,000 maximum while carrying an x10
random multiplier. Absurdly rare, but that's why the marketing max of
1,000x isn't a hard cap on a single round.
Why these multipliers aren't decoration
This is the mechanic people underestimate, and the sums show why. A
single fish colour covers 23 of 54 sectors and pays x2:
Nearly eleven points of the advertised return on a fish bet has to come
from random multipliers. They're doing real work. If you flat-bet a
colour through a stretch where no multiplier lands on your sector,
you're effectively on an 85% game, and the balance drops faster than
"96% RTP" makes it sound.
Working backwards, closing a 10.81-point gap with multipliers averaging
about x6 implies roughly 2.5% of winning rounds carry
one. That's our estimate, not a published figure. It still means random
multipliers are rare events doing heavy lifting, not a little extra that
shows up all the time.
