Lucky Neko Gigablox Slot Review
Yggdrasil Gaming’s Lucky Neko Gigablox represents a landmark release in the developer’s portfolio. Launched in June 2020, this Japanese-themed adventure introduced the Gigablox mechanic, a groundbreaking feature that would become Yggdrasil’s signature innovation across their expanding catalogue. The game combines traditional Asian aesthetic appeal with mechanical sophistication, creating an experience that appeals equally to players seeking visual charm and those pursuing substantial win potential.

Base Game & Features
Lucky Neko Gigablox operates on a 6-reel, 4-row grid with 40 paylines during base gameplay. The mechanics revolve entirely around the Gigablox system, which generates synced symbol blocks across the reels on every spin. In the base game, these blocks reach sizes of 2×2, 3×3, or 4×4, dramatically expanding the number of winning combinations available compared to standard grid-based slots.
The Wild symbol substitutes for any regular symbol to complete winning combinations. Scatter symbols, depicted as Lucky Neko cat faces, trigger the bonus feature and function within the Gigablox mechanic itself, meaning larger Gigablox scatter blocks count as multiple regular scatters for bonus calculation purposes. This integration creates more frequent bonus triggers than traditional scatter systems, adding genuine strategic depth to the base game experience.

Special Symbols & Modifiers
Beyond the standard Wild and Scatter symbols, Lucky Neko Gigablox features the Gigablox mechanic as its core modifier. Each spin generates at least one synced block of matching symbols, creating win potential that scales with block size. Community feedback emphasises that whilst base game Gigablox appearances occur frequently, the mechanical repetition can feel predictable over extended sessions. However, the feature’s core appeal remains intact: larger blocks mean larger payouts, and the visual satisfaction of watching synced symbols align delivers the mechanical engagement the game promises.

Lucky Neko Gigablox Free Spins
Free spins trigger when players land 5 or more scatter symbols anywhere on the reels. Each scatter awards 1 free spin, with a minimum of 5 free spins granted. Crucially, Gigablox scatter symbols count as multiple regular scatters—for example, a 4×4 Gigablox scatter block counts as 16 scatters toward the bonus trigger. This integration means bonus rounds occur with genuine frequency, and the larger the Gigablox block that triggers them, the more spins awarded.
During the free spins bonus, the game expands dramatically. The grid transforms to 6 reels and 8 rows, expanding paylines from 40 to 85 combinations and significantly amplifying win potential. Gigablox blocks also expand in size, reaching up to 5×5 and 6×6 dimensions during the bonus round. The expansion creates an almost chaotic visual experience where massive symbol blocks fill the screen, generating combinations that would be impossible to construct in the base game.
Blessed Symbols Feature
The Blessed Symbols feature activates exclusively during free spins. One random symbol per free spins session receives a 5x payout multiplier applied to all winning combinations containing that symbol. This feature does not appear in the base game, making the free spins experience distinctly different from standard gameplay. The multiplier significantly boosts winning potential when the blessed symbol participates in high-value Gigablox combinations during the expanded 6×8 grid.
Free spins can retrigger, meaning additional scatter landings during bonus play extend the feature and reset the blessed symbol to a new random selection. This retrigger potential creates scenarios where extended free spins sessions can deliver genuinely massive payouts, particularly when Gigablox blocks align with the current blessed symbol.
Our Honest Verdict
Rating: 4.5/5
Lucky Neko Gigablox stands as a well-crafted mechanically innovative slot that justifies Yggdrasil’s investment in the Gigablox system. The 96.4% RTP sits well above industry average, and the high volatility with a 15.45% hit frequency delivers genuine tension between base game dry spells and bonus round explosions. The 6,953x maximum win is genuinely achievable, particularly when Gigablox blocks align with blessed symbol multipliers during expanded free spins grids.
The game’s standout strength is mechanical innovation. The Gigablox system feels fundamentally different from standard grid-based slots, and the expansion during free spins creates visual spectacle that translates into legitimate win potential. For players seeking Yggdrasil’s signature experience or those curious about the Gigablox evolution, Lucky Neko delivers comprehensively.
The primary limitation is pacing. Base game Gigablox appearances occur so frequently that the feature’s visual novelty diminishes over extended sessions. Community feedback consistently notes this repetition, acknowledging that while the mechanic remains strategically sound, the aesthetic familiarity can wear thin. The high volatility also means casual players or those on modest bankrolls may experience frustratingly long dry spells between bonus triggers.
Lucky Neko Gigablox suits experienced players comfortable with high volatility gameplay, particularly those drawn to mechanical innovation over traditional narrative or licence-based themes. It represents a genuine advancement in Yggdrasil’s portfolio and remains a benchmark for what Gigablox mechanics can achieve. However, those seeking more varied base game action or lower volatility experiences should explore alternative options.
