Bonus features


Pays for himself. Appears on all reels (only during free game). Substitute for all symbols except SCATTER.



Does not pay for himself. Appears on any reels during base game. 3 Scatters give 10 FS, 4 scatters – 15, 5 – 20.


Fish Moneys

Game has money symbol – Fish. Each fish at screen can have some moneys award.

Players get award only if fisherman appears at screen. If few fishermen at screen – each will collect fishes. For example – if we have 5 fishes with total prize 100 and 2 fishermen – win will be 100 + 100 = 200.


Free Games

Free game starts if 3 or more scatters appears at screen. During free game we have 4 stages.

Stages control by total count of fisherman during FG Each 4 fishermen increase stage (raising the level happens only at last free spin of current level – if we have enough fishermen). To control total count of fishermen and levels – we use 2 accumulative. The diff between level – it is multiplier at fisherman for fish money value. 1x for level 1, 2x – for level 2, 3x for level 3 and 10x for level 4. On each level up we get +10FS.


Dynamite feature

Another part of the bonus is to only spin a single fisherman in view with no fish, the fisherman then throws a stick of dynamite and some symbols in view will change to fish and pay as normal. From server side it is Symbol Replacement feature. This is “Smoke and mirror” – because in fact fishes was at screen from beginning – and we just make fake symbol replacement.
