Rainbow Riches Free Spins embraces an Irish folklore aesthetic centered on the classic imagery of rainbows and pots of gold. The visual presentation draws heavily from traditional Celtic motifs and the mythological association between leprechauns, rainbows, and hidden treasures.
The game background features a purple gradient sky transitioning from deep purple to soft pink hues. Multiple vibrant rainbow arcs are layered to create visual depth and dimension. Silhouettes of trees appear at the bottom of the screen, grounding the mystical scene. The color palette combines purple and gold as primary colors, with the full rainbow spectrum serving as secondary colors and green accents emphasizing the Irish cultural theme.
The 5x3 reel grid is enclosed within an ornate golden Celtic-style frame featuring intricate patterns and traditional motifs. Behind the spinning symbols sits a gray gradient background providing contrast and visual clarity. Subtle vertical divider lines separate each of the five reels. The overall frame design uses gold coloring to reinforce the pot of gold folklore element central to the theme.
When the game initializes, players see the title Rainbow Riches Free Spins displayed in large golden letters with red outline styling against a purple sky background featuring a prominent rainbow. A blue progress bar contained within a black background bar appears at bottom center to indicate loading status. The Powered by SG Interactive logo sits in the bottom left corner, while the Barcrest logo enclosed in a blue oval occupies the bottom right position.
The highest value symbol displays the game logo featuring rainbow-colored text on a green background. This symbol represents the premium tier of payouts.
A medium-high value symbol showing the letter A in red with decorative font styling. Second highest paying regular symbol.
A medium value symbol displaying the letter K in blue with decorative font. Third highest paying symbol.
A low-medium value symbol showing the letter J in golden yellow with decorative font.
A low-medium value symbol displaying the letter Q in green with decorative font.
A low value symbol showing the number 10 in purple with decorative font styling.
Special substitution symbol featuring a Leprechaun character wearing a green hat. Substitutes for all symbols except the Bonus/Free Spins symbol. Can appear on any reel during base game play.
Function: Creates winning combinations by replacing missing symbols on active paylines.
Special trigger symbol appearing as a circular badge displaying FREE SPINS text. Only appears on reels 1, 3 and 5. Triggers the free spins bonus feature when 3 land simultaneously.
Dual Function: Acts as both bonus trigger and Wild symbol during free spins feature.
Rainbow Riches Free Spins employs a fixed 10-payline system where all lines remain permanently active at every stake level. Players cannot deactivate individual paylines, which simplifies the gameplay experience and ensures consistent coverage across all winning paths. The total stake is automatically divided by 10 to calculate the stake per line value.
The game provides a visual representation of all 10 payline patterns using a golden grid overlay on the 5x3 reel structure. Active positions on each payline are marked with red squares, while inactive positions appear as black squares against the golden grid background. This visualization helps players understand the various winning paths available during gameplay.
The Free Spins bonus feature activates when exactly 3 Bonus symbols land simultaneously on reels 1, 3 and 5. These Bonus symbols are circular badges displaying FREE SPINS text and are programmed to appear only on these three specific reels. No Bonus symbols appear on reels 2 or 4, ensuring the trigger mechanism requires precise symbol placement.
Upon triggering, players are presented with a selection screen displaying the Rainbow Riches Free Spins title and subtitle. The screen shows the instruction: BONUS SYMBOL ON REELS 1, 3 AND 5 INITIATES THE FREE SPIN BONUS. Three distinct configuration options are offered:
This option displays 3 stacked Bonus symbols arranged vertically. Awards 10 free spins. Represents the lowest spin count but may feature beneficial stacking patterns during the bonus round.
This option shows 5 Bonus symbols in a different arrangement pattern. Awards 15 free spins. Provides a middle-ground option balancing spin quantity with symbol positioning.
This option presents 6 Bonus symbols in yet another unique arrangement. Awards 20 free spins. Offers the maximum number of initial free spins among the three choices.
Players select their preferred configuration and confirm their choice using the green checkmark button positioned at bottom center of the selection screen.
During the free spins feature, the game employs an alternative set of reels distinct from the base game configuration. This alternative reel set is specifically designed with a higher frequency of Bonus symbols and potentially enhanced winning combinations. The reel strips are weighted differently to provide increased bonus potential compared to standard play.
A key mechanic during free spins is the ability for Bonus symbols to stack on reel 1. Stacked symbols occupy multiple vertical positions on the same reel simultaneously, appearing as a continuous block. When Bonus symbols stack on reel 1, they create multiple instances of the symbol that can contribute to triggering additional features or creating expanded winning patterns.
The free spins feature can be retriggered while already active. Landing 3 Bonus symbols again on reels 1, 3 and 5 during free spins awards additional spins that are added to the current remaining total. There is no programmed limit to the number of times the feature can retrigger, allowing for extended bonus sessions.
The game enforces an absolute maximum of 999 total free spins. This cap prevents indefinitely long bonus sessions and serves as a practical upper boundary. The free spins feature terminates when either the spin count reaches zero or the 999 maximum limit is achieved.
All free spins play at the same bet level that triggered the bonus feature. The stake per line and total stake remain locked at the values set during the triggering spin. This ensures that the bonus feature outcomes are directly correlated to the player's initial wager.
During free spins, the Bonus/Free Spins symbol assumes a dual role. In addition to its triggering function, it also acts as a Wild symbol, substituting for all other symbols except itself when forming winning combinations. This significantly increases the winning potential during the bonus round.
Rainbow Riches Free Spins includes a comprehensive autoplay system allowing for automated consecutive spins with customizable parameters and built-in responsible gaming controls.
Players can configure autoplay to run for a predetermined number of spins. Available options are:
As a responsible gaming measure, players can set maximum loss thresholds. When total losses reach the selected limit, autoplay automatically terminates. Available loss limit options are:
This feature protects player bankrolls during extended automated sessions by preventing losses beyond the preset comfort level.
Players can configure autoplay to pause when any single spin results in a win exceeding a specified amount. This allows review of significant wins and decision-making about whether to continue playing. Options include:
The autoplay interface provides two primary control buttons. A red CANCEL button with white text allows immediate termination of autoplay at any time. A gray START button with white text initiates the autoplay sequence once parameters are configured. These controls give players full authority over automated gameplay.
The Gamble feature provides an optional risk-reward mechanism available after any winning spin. When a win occurs during base game play, the gamble button becomes active, indicated by a playing card back design icon within a red square frame with golden border.
Activating the gamble feature allows players to wager their total win amount from the triggering spin for the opportunity to increase the payout. The specific mechanics of the gamble game itself are presented within the feature interface once activated. Players can choose to collect their win directly or engage the gamble for potential enhancement.
A small bottle graphic appears at the bottom of the gamble button icon as an additional visual identifier. The button only activates in a winning state and remains inactive during losing spins or when no win has occurred.
The interface is organized into distinct functional areas. The center of the screen displays the 5x3 reel grid enclosed in its golden Celtic frame. The left panel houses game controls and stake settings. The right panel contains primary action buttons including spin, autoplay, gamble and information access. The bottom bar shows balance and win information along with provider branding.
A clearly labeled STAKE display with black background and yellow text shows the current total stake amount. This value represents the total bet per spin across all 10 active paylines.
Below the total stake, a STAKE/LINE display with identical black background and yellow text styling shows the calculated stake amount per individual payline. This value is automatically computed as the total stake divided by 10.
Positioned between the stake displays are two triangle-shaped buttons. A red downward-pointing triangle decreases the stake when clicked. A green upward-pointing triangle increases the stake. These controls allow players to adjust their bet amount within the 0.10 to 500.00 range.
A LINES display with black background and yellow text shows the value 10, representing the fixed number of active paylines. This value cannot be changed as all lines are permanently active.
A blue circle containing a lowercase i symbol provides access to comprehensive game information. Clicking this button opens screens detailing the paytable, rules, payline patterns and feature explanations.
A gear or cog symbol button opens the game settings menu, allowing players to customize options such as sound volume, graphics quality, spin speed and display preferences.
The primary action button features a large green play arrow pointing right, enclosed within a golden ornate frame. Clicking this button initiates a single spin, consuming the current stake amount and setting the reels in motion.
Displayed as circular refresh arrows within a green square bordered by a golden frame. Clicking opens the autoplay configuration menu where players set spin counts and limits before starting automated play.
Shows a playing card back design with a small bottle graphic at bottom, enclosed in a red square with golden frame. Only becomes active after winning spins, allowing players to risk their win for potential increase.
A blue i information symbol within a blue square bordered by golden frame provides an alternative access point to game information and help screens.
Located at bottom left, the Balance label with numeric value in yellow text on black background shows the player's current account balance. Formatted with two decimal places for currency precision. Updates automatically after each spin completes.
Positioned at bottom right, the Total Win label with numeric value in yellow text on black background shows the accumulated winnings from the most recent spin. Displays the combined total from all winning paylines. Also formatted with two decimal places.
The center of the bottom bar displays the Barcrest provider name in blue text within an oval frame, identifying the game developer brand within the Scientific Games portfolio.
To achieve a winning combination, symbols must appear on an active payline starting from the leftmost reel. The symbols must be consecutive with no gaps between reels. A combination is only valid if it begins on reel 1 and extends continuously across adjacent reels.
When multiple winning combinations of the same symbol occur on a single payline, only the highest value win is paid for that specific line. For example, if both a 3-of-a-kind and 4-of-a-kind combination appear on the same payline, only the 4-of-a-kind payout is awarded. This prevents duplicate counting of overlapping symbol matches.
Wins occurring on different paylines are independent and additive. If winning combinations appear on multiple paylines simultaneously, the payout from each winning line is calculated separately and all amounts are summed together for the total win displayed.
In accordance with fair gaming practices and regulatory requirements, each game outcome is completely independent of all previous and future results. A certified Random Number Generator determines all outcomes. The probability of any specific result is identical at the start of every game, regardless of previous playing history, wins, losses or any other factor.
The theoretical RTP of 95.17% represents the expected long-term return calculated over millions of game rounds. This is a statistical average and does not guarantee any specific results in individual sessions. Short-term results can vary significantly from the theoretical RTP due to variance and random distribution.
The game enforces a maximum win limit of 250,000.00 currency units per single game. This cap applies regardless of stake level or combination of wins. Due to stake dependency, this maximum may not be mathematically achievable from all bet levels. The cap protects the operator while still allowing for substantial player wins.
In the event of any technical malfunction, hardware failure, software error or communication disruption, all pays and ongoing plays are voided. This is standard industry practice to protect both players and operators from the consequences of technical errors. Any affected games would typically be refunded at the original stake amount.
When the game is not actively spinning, it exists in idle state. The green spin button is active and ready to accept input. The current balance is displayed accurately in the bottom left position. If a win occurred on the previous spin, the total win amount remains visible in the bottom right display.
When reels are in motion, symbols appear as blurred vertical streaks creating the illusion of rapid rotation. The spin button may be disabled to prevent accidental double-clicks during active play. The balance information updates only after the spin completes and all results are evaluated and awarded.
Following a winning spin, the game enters win presentation mode. Winning paylines are highlighted sequentially, each illuminating briefly to show the player which lines produced wins. The total win value accumulates in the display, building from zero to the final amount. During this state, the gamble button becomes active if applicable, allowing the player to risk the win.
When free spins are running, the interface displays a dedicated spin counter showing the number of remaining free spins. The accumulated total of all free spins winnings is tracked separately and displayed prominently. Free spins continue automatically without requiring manual spin button clicks, though players retain the ability to view results between spins.
Recognizing that a portion of the player base experiences color vision deficiency, Rainbow Riches Free Spins implements multiple accessibility measures. Each symbol is differentiated not only by color but also by unique shape characteristics and letter or number identifiers. The J, Q, K, A and 10 symbols are clearly marked with their respective characters. Buttons can be identified by their distinct shapes and icon designs beyond just color coding. Winning lines are indicated through animation effects and highlighting that do not rely solely on color perception.
The interface accommodates players with motor control limitations through several design choices. All primary control buttons feature large clickable areas that do not require precise mouse positioning. The autoplay feature reduces the need for repetitive clicking during extended play sessions. Stake adjustment uses simple up and down controls that are easy to target and activate.
For players with reduced visual acuity, the game employs high contrast design principles. Key information appears as bright yellow text against black backgrounds, providing maximum readability. Important numerical values use bold, large font sizes. Symbols maintain distinct contrast against their background, ensuring visibility. The overall visual hierarchy emphasizes crucial information through size and contrast rather than subtle color variations.
The fixed payline system simplifies gameplay by eliminating complex line selection decisions. All buttons and displays feature clear text labels explaining their function. Comprehensive help screens accessible via the information button provide detailed explanations of all game mechanics, ensuring players can understand the rules regardless of prior slot game experience.
