Release the Kraken 2

Release the Kraken 2 - 463-Spin Underwater Expedition With Pragmatic Play's Enhanced Sequel and Its Colossal Symbol Mechanic

The original Release the Kraken was a solid deep-sea adventure slot, and Pragmatic Play's sequel expands on it with the addition of a Colossal Symbol feature and enhanced bonus buy options. Over 463 tracked spins, we found a game that combines an above-average 96.50% RTP with medium-high volatility and a free spins round where the enormous Kraken symbols can dominate the grid. Our peak win of 247x came during a session where a 4x4 Colossal Kraken wild appeared alongside premium symbols, and the underwater theme was executed with genuine visual flair. Here is the full analysis for Singapore players.

Pragmatic Play's Deep-Sea Franchise

Pragmatic Play has built several successful sequel franchises - Big Bass Bonanza, Gates of Olympus, and now Release the Kraken. The sequel strategy allows them to capitalise on established brand recognition while introducing mechanical improvements that address feedback from the original. In the case of Release the Kraken 2, the primary addition is the Colossal Symbol mechanic that allows oversized symbols (up to 4x4 positions) to appear on the reels.

The original game was a competent 20-payline slot with Treasure Chest respins. The sequel expands to include more varied feature types and the Colossal Symbol system, which fundamentally changes the win dynamics when these massive symbols appear. It is a meaningful upgrade rather than a cosmetic refresh.

Pragmatic Play's global licensing coverage, including MGA and UKGC authorisation, provides regulatory assurance. The 96.50% default RTP places this firmly in the above-average category, though reduced versions may be deployed by some operators.

Technical Specifications

Layout: 5 reels, 4 rows with 20 fixed paylines in the standard configuration. When Colossal Symbols appear, they effectively create a larger visual footprint on the grid, though the payline structure remains at 20 lines.

RTP: 96.50% at the default configuration. This is a strong figure that provides genuine mathematical value. The half-percentage-point advantage over a standard 96% game translates to meaningful savings over extended play - approximately SGD 6.75 per SGD 1,350 wagered.

Volatility: Medium-High (4 out of 5). The Colossal Symbol mechanic adds variance spikes to an otherwise moderate base game. When oversized symbols appear and align favourably, wins can be substantial. When they do not appear, the game plays like a standard medium-volatility slot.

Bet Range: SGD 0.01 (EUR 0.01) minimum to SGD 0.68 (EUR 0.50) maximum. The very low maximum bet is a significant limitation. This game is clearly designed for casual, low-stakes entertainment. Players who typically bet SGD 1 or more per spin will find this unusable at their preferred stake level.

Max Win: 5,000x your stake. At the maximum bet of SGD 0.68, this represents a theoretical maximum of SGD 3,400 - modest but the game is not designed for chasing large absolute payouts.

Beneath the Waves - Visual Quality

The underwater theme is executed with genuine artistry. The background depicts a deep ocean environment with rays of sunlight penetrating from above, coral formations, and schools of fish swimming past the reels. The colour palette uses rich blues, teals, and greens that create a convincingly subaquatic atmosphere. Bioluminescent effects add depth and visual interest.

Symbol design centres on marine creatures and ocean artefacts. Premium symbols include the Kraken itself, various sea creatures (sharks, octopi, anglerfish), and treasure items. Low-value symbols are styled as ancient sea-weathered coins and gems. The Kraken symbol is particularly well-designed - detailed tentacles, glowing eyes, and imposing presence that makes it immediately recognisable even when it appears as a standard 1x1 symbol.

When the Colossal Kraken appears as a 3x3 or 4x4 symbol, the visual impact is dramatic. The enormous creature fills a significant portion of the grid, tentacles reaching across multiple reel positions. It is one of the more visually impressive moments we have encountered in slot gaming, and it occurs frequently enough to maintain novelty across a full session.

Sound design complements the visuals with an underwater ambient soundscape - bubbling water, distant whale calls, and a gentle orchestral score. Feature activations trigger more dramatic audio cues, including the Kraken's roar when Colossal Symbols appear. The audio environment is immersive and well-produced.

Base Game and Colossal Symbols

The base game operates on 20 paylines with standard left-to-right win evaluation. Our hit frequency was approximately 1 in 3.3 spins, which is healthy for a 20-payline game and keeps the base experience active.

Colossal Symbols can appear randomly during any base game spin. These oversized symbols (2x2, 3x3, or 4x4) occupy multiple positions simultaneously and are evaluated against the paylines as if each position contains the symbol individually. A 3x3 Kraken wild, for example, acts as 9 individual wild symbols placed on the grid, dramatically increasing the chances of completing winning combinations.

In our 463 spins, Colossal Symbols appeared approximately once every 20 spins. The size distribution we observed was roughly: 2x2 (most common, about 65% of appearances), 3x3 (about 30%), and 4x4 (rare, about 5%). The 4x4 appearances were by far the most valuable, with one producing a base game win of 42x stake.

Free Spins Feature

Three or more scatter symbols trigger the free spins round. We received 8 free spins from 3 scatters on each of our triggers. During free spins, Colossal Symbol frequency increases, and the Kraken wild Colossal appears more often.

We triggered free spins 5 times across 463 spins (1 in 93 spins):

• Trigger 1: 8 free spins, two 2x2 Colossal appearances, returned 24x stake
• Trigger 2: 8 free spins, one 3x3 Colossal Kraken wild, returned 87x stake
• Trigger 3: 8 free spins, three 2x2 Colossals, returned 34x stake
• Trigger 4: 8 free spins, one 4x4 Colossal Kraken wild, returned 247x stake (peak win)
• Trigger 5: 8 free spins, two 3x3 Colossals, returned 112x stake

The 247x peak win resulted from a 4x4 Colossal Kraken wild that appeared on reels 2 through 5, effectively creating 16 wild positions across the grid. Combined with premium symbols on reel 1, this produced winning combinations across virtually all 20 paylines simultaneously - a spectacular visual and financial moment.

Average bonus return: 100.8x stake. The correlation between Colossal Symbol size and total return is clear from our data, with 4x4 appearances driving the largest payouts by a significant margin.

Treasure Chest Respins

In addition to the free spins feature, Release the Kraken 2 includes a Treasure Chest respin mechanic. When Treasure Chest symbols land on the reels, they lock in place and award respins similar to a Hold and Win format. Each chest carries a cash value, and landing additional chests during respins adds to the total and resets the respin counter.

We triggered the Treasure Chest feature 3 times across 463 spins, with returns of 8x, 15x, and 28x stake. This feature provides smaller but more frequent supplementary returns that help sustain the overall session flow.

Mobile Experience

The underwater theme translates beautifully to mobile screens. Tested on a Samsung Galaxy S24 using Singtel 4G. The bioluminescent colour palette looks stunning on AMOLED displays, with deep ocean blues and glowing effects that benefit from the screen technology. Colossal Symbol animations are smooth and visually impressive even on smaller screens - the 4x4 Kraken filling most of the grid is genuinely spectacular on a phone display. Load time of 1.8 seconds and battery drain of approximately 6% per hour are both excellent.

Bankroll Strategy

The dual-feature system (free spins plus Treasure Chest respins) provides a combined trigger rate of 1 in 58 spins, which is reasonably frequent. Combined with the healthy base game hit frequency, bankroll decline is manageable. We recommend 200x your bet level as a starting reserve. The very low maximum bet (SGD 0.68) naturally limits total risk exposure.

Our Verdict

Release the Kraken 2 excels where it matters most - the Colossal Symbol mechanic creates genuinely exciting visual and financial moments that distinguish it from standard slot experiences. The 247x win from a 4x4 Colossal Kraken wild was one of the most visually dramatic results in our review batch. The 96.50% RTP is above average, the dual-feature system keeps sessions varied, and the underwater theme is executed with genuine artistry. The primary limitation is the very low maximum bet, which restricts the game to casual and low-stakes play. For Singapore players within that stake range, Release the Kraken 2 is a well-crafted slot that delivers distinctive entertainment value through its headline Colossal Symbol feature.
