Blue diamond symbols act as Wild multipliers from 1x to 10x, substituting for all paying symbols. Each Liberty Gem triggers a Freedom Respin, with gems staying locked on the grid for consecutive respins until no new gems land.
Landing 4 or more Liberty Gems in a square formation creates a Gem Cluster. Formations of 2x2, 3x3, 4x4 or 5x5 combine multipliers and grow when additional gems land adjacent to existing clusters.
In Epic Clusters, all multipliers are added together, then the total is multiplied by a random value between 2x and 10x. The final multiplier applies to all winning paylines the cluster participates in.
Every Liberty Gem landing triggers an automatic respin with all gems remaining locked in position. Respins continue as long as new Liberty Gems keep landing, creating chain reactions of increasing multipliers.
The 5x4 grid features 19 fixed paylines including straight horizontals, V-shaped patterns, zigzags and diagonals. Only the highest win per payline is paid, with multiple wins added together.
Activate FeatureSpins for 3x increased probability of triggering bonus games on every spin. This mode remains active until manually disabled, giving you enhanced bonus hunting capabilities.
Triggered by 3 FS scatter symbols. All Liberty Gems remain sticky on the grid throughout free spins. Landing additional FS symbols during the feature awards extra free spins. RTP: 96.31%
Triggered by 4 FS scatter symbols. All Liberty Gems and Gem Clusters become sticky and remain locked. Landing 2 FS adds 2 spins, 3 FS adds 4 spins. Highest RTP: 96.34%
Hidden epic bonus triggered by 5 FS scatter symbols. At least 5 Liberty Gems guaranteed to land on each spin, excluding Freedom Respins. Maximum potential for massive cluster formations.
Ultimate Slot of America delivers a mathematically sophisticated slot experience wrapped in patriotic American iconography. Hacksaw Gaming's 5-reel, 4-row grid with 19 fixed paylines creates a unique gameplay structure where the Liberty Gem Wild multiplier system becomes the central mechanic driving both base game excitement and bonus feature potential.
The Liberty Gem symbol functions as a Wild with multiplier values ranging from 1x to 10x. What separates this from standard Wild mechanics is the Freedom Respin trigger: every Liberty Gem landing initiates an automatic respin with all gems locked in position. This creates a cascading probability system where each respin can potentially add more gems, extending the chain reaction.
The Gem Cluster formation mechanic adds exponential multiplier growth. When 4 or more Liberty Gems land in square formations (2x2, 3x3, 4x4, or 5x5), they combine into a single cluster. The mathematical progression becomes particularly interesting in Epic Clusters, where all multipliers are first summed, then multiplied by a random value between 2x and 10x. A 3x3 cluster with nine 5x multipliers would sum to 45x, potentially reaching 450x if the Epic multiplier hits 10x.
Spin-Dependence Day (3 FS symbols) provides 10 free spins with sticky Liberty Gems. The RTP of 96.31% reflects a balanced volatility profile where gem accumulation occurs gradually. The retrigger mechanism allows for extended sessions when additional FS symbols land during the feature.
Red, White, Bling! (4 FS symbols) elevates the mechanic by making both individual gems and formed clusters sticky. The 96.34% RTP marks this as the highest-returning bonus mode. The progressive spin addition (2 FS = +2 spins, 3 FS = +4 spins) creates potential for extended features with maximum gem coverage.
Pursuit of Riches represents the hidden epic bonus, triggered by 5 FS symbols. The guaranteed minimum of 5 Liberty Gems per spin (excluding respins) dramatically increases cluster formation probability. This mode targets the 10,000x maximum win potential through concentrated gem coverage and Epic Cluster multiplier stacking.
The paytable follows a clear three-tier structure. Low-paying card symbols (J, Q, K, A) in three-dimensional blue styling pay 0.10x for five-of-a-kind. Medium-tier thematic symbols (baseball, hamburger, Statue of Liberty head) maintain consistent 0.20x payouts for five matches. The eagle superhero symbol dominates as the premium, paying 1.00x for five-of-a-kind, 0.50x for four, and 0.15x for three.
The Liberty Gem itself pays 1.00x for five-of-a-kind before multipliers apply, but its true value lies in the multiplier and respin mechanics rather than line pay contributions.
The Bonus Buy menu offers five distinct purchase options, each with specific RTP values. BonusHunt FeatureSpins at 96.28% RTP provides 3x increased bonus trigger probability at minimal cost increase. Freedom FeatureSpins (96.29% RTP) guarantees one Liberty Gem every third spin. USA Epic Drop FeatureSpins reaches 96.30% RTP with enhanced gem landing frequency.
Direct bonus purchases for Spin-Dependence Day and Red, White, Bling! allow immediate access to free spin modes at their respective RTP values, bypassing base game variance entirely.
The 19 payline structure includes horizontal lines, V-patterns, zigzags, and diagonals, creating multiple evaluation paths for each spin. The "highest win per payline" rule means overlapping symbol combinations only count once per line, making Liberty Gem positioning critical for multiplier application across multiple paylines simultaneously.
The Freedom Respin mechanic creates a risk-reward decision point in bonus buy scenarios. Purchasing BonusHunt FeatureSpins provides enhanced trigger probability while maintaining base game flexibility, whereas direct bonus purchases commit to specific feature mechanics immediately.
The 10,000x maximum win applies across all game modes. When this threshold is reached, the round immediately ends and remaining free spins or bonus features are voided. This cap affects strategy in extended bonus features where Epic Cluster formations could theoretically exceed the limit through multiplier stacking.
The game implements interrupted play protection, maintaining round state for 180 days before forfeiture. Incomplete rounds resume upon reconnection, with outcomes determined by the random number generator at spin initiation rather than display completion.
Version 2.0.235 includes comprehensive keyboard navigation with 15 documented hotkeys covering sound toggles, bet adjustment, bonus menu access, and autoplay configuration. The Turbo and Super Turbo modes accelerate spin resolution while maintaining RNG integrity. Autoplay supports advanced stop conditions including loss limits, single win limits, and feature win triggers.
The game meets European Accessibility Act (Directive EU 2019/882) requirements with detailed screen reader support and motor disability accommodations through extended keyboard control implementation.
While Hacksaw Gaming does not publish explicit volatility ratings, the mathematical structure suggests medium-high volatility. The Liberty Gem respin mechanic creates base game hit frequency through guaranteed respins on Wild lands, while the bonus features concentrate variance through sticky mechanics and multiplier accumulation.
The RTP range of 96.28% to 96.34% across different modes provides player choice in risk-reward profiles. Red, White, Bling! offers the highest theoretical return but requires 4 FS symbols to trigger naturally, creating higher volatility compared to the more accessible Spin-Dependence Day at 3 FS symbols.
Ultimate Slot of America is a game of chance with real money risk. The RTP of 96.28-96.34% means the house edge is 3.66-3.72%. Set deposit limits before playing. Never chase losses. Gambling should be entertainment, not income. If gambling stops being fun, seek help immediately.
