Tropicool 4

The series kicked off in 2021 with the first Tropicool, continuing with two more episodes that steadily enriched and refined the game mechanics. Now it’s time to dive into this icy vacation to discover the new surprises the crazy group has in store.

Available online since February 4, 2025, the slot offers 6 reels, 6 rows and up to 46,656 ways to win. To win, you just need to line up at least 3 symbols on consecutive reels starting from the first reel on the left, a simple mechanism that perfectly matches the game’s adrenaline-fueled pace.

Players can choose a bet ranging from $0.20 as the minimum amount up to a maximum of $100. With a maximum RTP that stands at 94.00%, medium to high volatility and a maximum payout that can reach as much as 25,000 times the bet, while the payout frequency in the base game stands at around 24.1%.

Tropicool 4’s medium to high volatility makes the game particularly suitable for thrill-seekers who are not deterred by a few empty spins while waiting for bigger prizes. This type of volatility means that winnings may be less frequent, but generally larger amounts when they do arrive.

Symbols of Tropicool 4

The symbols in Tropicool 4 are divided into two main categories, and each offers its maximum payout when you manage to line up 6 equal symbols on consecutive reels. This simple and intuitive payout structure adds a touch of strategy to the game, encouraging players to look for the best combinations for big rewards.

The paytable distinguishes between low-value and high-value symbols. Low-value symbols are represented by pear-like fruits of different colors, including purple, green, yellow and pink, each of which pays 0.25 times the bet for a combination of six identical symbols. High-value symbols include more valuable fruits, such as an apple, a lime, a pineapple, a dragon fruit and a strawberry, which can offer prizes between 0.3 and 2 times the bet for complete combinations.

Bonus features of Tropicool 4

This slot is distinguished by its rich array of special features and symbols, which offer dynamic and compelling gameplay. Each game is enhanced by unique mechanics and exciting bonuses, which we will explore in detail. In addition to the standard features, this slot also introduces the X-iter mode, which allows players to customize their experience by purchasing specific game modes.

Avalanche & Cool Reel

The Cool Reel is located above the main grid and plays a key role in gameplay. It contains 3 rows of function symbols, empty ice cubes and empty cells. The function symbols become active when they drop into the main grid, while the ice cubes act as spacers, separating the symbols.

Each game round begins in normal mode, with new symbols appearing in the main grid and new function symbols entering the Cool Reel from the right. When a winning combination is formed, the symbols involved are paid out and removed from the grid, except for the unconsumed Locked Wilds.

The remaining symbols slide down, leaving room for the Cool Reel function symbols, which fill in the empty cells. This process continues until winning combinations are formed, activating an avalanche effect. Once finished, the Mystery, Row Swap, Grid Flip and Bonus activator symbols are activated, in that order.

Big Symbol

Some pay and feature symbols may appear in increased size, covering areas of 2×2 or 3×3 cells. These symbols pay according to the number of standard 1×1 symbols they cover. For example, a 2×2 symbol equals 4 regular symbols, while a 3×3 symbol equals 9 symbols.

When a large symbol falls from the Cool Reel, it crushes and removes the symbols below in the main grid, unless they are function symbols or other large symbols, which prevent the symbol from falling further. If the symbol fails to fully enter the main grid, it splits into 1×1 symbols. Also, if a large symbol ends its fall on empty cells, it replicates, filling the empty cells with 1×1 symbols of the same type.

Flamingo Wild

The Flamingo symbol is a Walking Wild that appears in 1×2 or 1×3 sizes. It moves one column to the right with each step, awarding a free drop when there are no visible wins.
Each time it moves forward, it increases in height by 1 symbol, up to a maximum of 6 symbols. This process continues until the Flamingo exits the rightmost column.

Toucan Multiplier

The Toucan is a Walking Wild with a multiplier function. It appears in 1×3 size and advances to the right, rewarding with a free drop in the absence of wins. Each time it passes, it increases the overall multiplier by x1, which remains active until the end of the round. This cycle repeats until the Toucan leaves the grid.

Elmo Drop

Elmo is a special symbol that eliminates pay symbols on multiple rows when there are no visible wins. It initially appears in 1×1 size and becomes active when it can grow to 1×2 or 1×3. When active, Elmo removes all symbols on the rows it occupies, except for Bonus and Feature symbols.

The huge number of winning combinations offers significant potential for prizes, enhancing the gaming experience.

Locked Wild

Locked Wilds are loaded Wild symbols that can participate in up to 3 winning combinations before being removed. During the bonus game, these symbols remain active between free drops until they are completely consumed.

Mystery

Mystery symbols are revealed when there are no visible wins. All Mystery symbols turn into the same payout symbol or feature, except for bird symbols.

Row Swap

The Row Swap symbol substitutes all symbols on a row for the same pay symbol. If the selected symbol is the Flamingo, all symbols become Wild. The feature is activated at the end of the avalanche effect, after any wins and the revelation of the Mystery and Grid Flip symbols.

Grid Flip

The Grid Flip symbol swaps column positions (1 with 6, 2 with 5, 3 with 4) and turns into a Wild symbol. This function is activated only in the absence of winning combinations.

Bonus Game

The Bonus Game is activated when 3 or more Bonus symbols appear on the main grid. Depending on the number of Bonus symbols, players receive:

• 3 Bonus symbols: 6 free drops;
• 4 Bonus symbols: 9 free drops;
• 5 Bonus symbols: 12 free drops;
• 6 Bonus symbols: 15 free drops.

During the bonus game, the Cool Reel introduces Extra Drop symbols, which add 1, 2 or 3 extra free drops.
