Fishin' Madness QuadGrows by Posh Monkey Studios takes place beneath the sea, where Fish symbols carry prizes and a Fisherman collects their combined value. The QUADGROWS system gradually expands the grid from three to seven rows.
Available at BetVictor, it adds long term progression to familiar fishing themed slot games, unlocking more paylines, larger Fish values and stronger collection multipliers.
The game uses colourful cartoon artwork set among seaweed, coral and underwater machinery. Its symbols include a yellow submersible, diving helmet, oxygen tank and small purple sea creatures, alongside brightly coloured card ranks.
Four rows begin covered by seaweed. These layers disappear as QUADGROWS levels are completed, making the expanding grid a visible part of the underwater setting.
| Symbol Name | 2x | 3x | 4x | 5x |
|---|---|---|---|---|
| Yellow Submersible | 0.25x | 0.50x | 1x | 50x |
| Diving Helmet | - | 0.15x | 0.30x | 7.50x |
| Oxygen Tank | - | 0.15x | 0.30x | 7.50x |
| Treasure | - | 0.10x | 0.25x | 5x |
| Purple Sea Creatures | - | 0.10x | 0.25x | 5x |
| A, K, Q, J and 10 | - | 0.05x | 0.10x | 0.20x |
QUADGROWS expands the grid after 20, 50, 100 and 200 paid base game spins. Each level adds one row and ten paylines, increasing the layout from 5x3 with ten paylines to 5x7 with 50. The stages also unlock Fish values of 5x, 10x, 20x and 100x, alongside row specific Collect Multipliers of 2x, 3x, 4x and 5x.
Fish Instant Prize symbols appear on reels one to four, while the Fisherman appears on reel five. When both land, the Fisherman collects every visible Fish value. A multiplier applies only when the Fisherman lands on the unlocked row carrying that multiplier.
Fish that land without being collected contribute to the Fish Progress feature. This can activate on a later paid spin and guarantee that Fish symbols appear. Fish Progress operates only in the base game and remains inactive during free spins.
Three or more Bonus Scatters award eight free spins, while another three or more add eight further spins. The feature retains the rows already unlocked through QUADGROWS. Collect Multipliers increase to 2x, 3x, 4x, 5x, 6x, 10x and 100x across rows one to seven, although only currently active rows can be used.
The game begins with five reels, three rows and ten paylines. Wins use matching symbols on adjacent reels from left to right. QUADGROWS expands the grid one row at a time until it reaches seven rows and 50 paylines, while also improving the available Fish values and collection multipliers.
At BetVictor, we see the gradual reel expansion as the slot’s clearest distinction. The early layout is simple, but each QUADGROWS stage adds more paylines and collection potential.
Posh Monkey Studios has combined a familiar fishing format with progression that remains visible between paid spins. Players browsing our online casino may find it suited to longer sessions where unlocking the complete grid forms part of the gameplay.
