Tropicool 5 Slot by ELK Studios

Cool Reel, New Ocean

Tropicool 5 takes ELK's tropical franchise underwater. The 6x5 grid sits beneath a 2-row Cool Reel - the series signature. Feature symbols on the Cool Reel drop into the main grid after avalanches, feeding wilds, multipliers, mystery symbols, and character-specific features into play. 15,625 all-ways paylines, avalanche cascading, and a 25,000x max win cap that the series has maintained since entry two.

The grid shrank from 6x6 in earlier entries to 6x5 here. Fewer positions means fewer symbols in play, but the Cool Reel compensates by feeding more feature symbols per avalanche chain. And the min bet dropped to 0.10 EUR (most ELK games start at 0.20), making this the cheapest entry point in the series.

Four Characters, Four Jobs

Kyle the Crocodile is a 6x2 symbol that sits on the Cool Reel and drops mystery symbols into empty positions below. All mystery symbols reveal as the same payout type when no more wins remain. Kyle sliding across the Cool Reel means his mystery drops can cover different columns each time he activates.

Wild Eggs are sticky wilds that transform into birds when their column has empty space. Toucans stretch 1x2 to 1x3, Flamingos stretch 1x4 to 1x5. A Flamingo wild covering nearly an entire column is the equivalent of locking a full-column wild in place - and the egg stays as a wild until the bird hatches.

Elmo the Sloth collects pearls from clamshell symbols. This collection persists between rounds at the same bet level. When triggered, Elmo clears the top 3-5 rows and guarantees a full Cool Reel drop. Think of it as a slow-building reset button: pearls accumulate over many spins, then Elmo fires and reloads the entire grid with feature-heavy content from the Cool Reel.

Golden Symbols and Row Swap

Golden symbols carry positional multipliers: x2 on the top row, increasing by +1 per row down to x6 at the bottom. Same column = multipliers add. Different columns = multipliers multiply. Two golden symbols on the bottom two rows of different columns apply a x5 times x6 = x30 multiplier to that combination. This is the math behind 25,000x - stacked golden multipliers on the lower rows during a bonus with a global multiplier running.

Row Swap picks a symbol type and replaces an entire row with it. Fires after wins, mystery reveals, and Wild Egg activation - so it can trigger multiple times in a single cascade chain. Landing Row Swap on a row full of low-value symbols and converting it to the highest pay type shifts the entire round's value.

Bonus Structure

Three bonus symbols trigger 6 bonus drops (4 = 9, 5 = 12, 6 = 15). During the bonus, the Cool Reel adds Extra Drop and Multiplier symbols. Locked Wilds persist between drops with a charge counter that ticks down each win they participate in. The global multiplier builds from Cool Reel multiplier symbols and stays active across all drops.

X-iter runs from 3x (bonus hunt) to 500x (Super Bonus with 3 guaranteed Locked Wilds per drop). The 25x option guarantees 3 Locked Wilds on a single spin, which is a quick test of whether the golden symbol math connects on this particular session.
