TaDa Gaming has bolstered its slot catalog with the launch of 777 Rainbow Rampage, a five-reel, three-row game with 25 paylines that brings the classic 777 mechanic to a modern offering featuring multiple layers of bonuses and prize multiplication opportunities. The title introduces several standout features, such as expansive Wilds, Cash Coins, four levels of Jackpot, Free Spins, and the anticipated Hold & Spin, all set in a visual universe of leprechauns and rainbows aimed at traditional players and operators interested in medium-to-high volatility titles.

777 Gameplay and Key Symbols in 777 Rainbow Rampage

The game utilizes three types of '7' symbols —single, double, and triple— representing different prizes. Forming a winning combination requires aligning at least three matching '7' symbols on any of the reels, both in the base game and during Free Spins. If the '7's are of different types but align in a line, they still generate a payout, although at a lower value compared to a combination of identical symbols.

Expanding Wilds and Special Symbols: Collection Mechanics

The slot's Wild is represented by a leprechaun and substitutes for all symbols except Bonus and Cash. When it lands, it expands vertically, covering the entire reel. During the Free Spins round, these Wilds automatically transform into Wild Collect Symbols, enhancing the Cash Symbols collection function with multipliers set at 2x, 3x, 5x, or 10x based on the outcome. When multiple lines match with expanded Wild Collect Symbols, the multipliers are combined to increase the overall prize, making each spin potentially lucrative.

Bonus symbols, depicted as a rainbow emerging from a pot of gold, only appear in the base game. Three Bonus symbols trigger 8 Free Spins, four yield 10, and five grant 12 free spins. During Free Spins, the entire Cash Symbols collection mechanic and multipliers take center stage.

Jackpot Structure and Hold & Spin Mechanics

In both modes (base game and Free Spins), Cash Symbols can appear with values ranging from 0.5x to 10x the total bet. Additionally, four Jackpot Coins —Mini (15x), Minor (50x), Major (250x), and Grand (1,000x the bet)— provide access to additional fixed prizes. The Hold & Spin mechanic activates by landing six or more Cash Symbols in any position, and it can trigger in both the base game and Free Spins. When triggered, all Cash Symbols are grouped to offer a sequence of three free spins, which are reactivated each time a new Coin lands. This cycle keeps the function alive as long as additional Cash Symbols continue to appear.

Modifiers and Random Features: Rainbow Feature and Gold Toss

Within Hold & Spin, there are three Modifier Coins:

  • Green 'Collect': collects the value of all Cash Coins on the screen.
  • Blue 'Add to All': adds its value to each existing Cash Coin.
  • Red 'Double Up': randomly selects between two and five coins to double their value.

If a full reel is filled with Cash Symbols during Hold & Spin, their combined value is transferred to a lateral Pot of Gold. This can randomly trigger the Rainbow Feature, which upgrades Wilds to Wild Collect, or the Leprechaun’s Gold Toss, which re-spins a series of Cash Symbols onto random positions on the reels.

Both the Rainbow Feature and the Leprechaun’s Gold Toss can also appear in the base game, creating new opportunities to collect Cash Symbols, activate Wild Collect, and meet the requirement of six symbols to return to the Hold & Spin sequence.

Studio Opinion and Implications for Operators

Sean Liu, Director of Product Management at TaDa Gaming, summarized the offering:

“777 Rainbow Rampage gives players the classic 777, but expanded with expansive Wilds, Rainbow enhancements, Cash collection, four levels of Jackpot, Modifier Coins, Free Spins, and Hold & Spin. The variety of bonus routes means that each spin can change the dynamics of the game.”

For operators and content aggregators in regulated markets, TaDa Gaming's approach expands the slot offering with an alternative that combines well-known standard mechanics in Latin America and Europe with innovations in multipliers and Hold & Spin cycles, aligning with the demands of experienced players.

Moreover, the Boost Play mode increases the likelihood of accessing Free Spins, diversifying paths to reach bonus rounds —an appealing option for high-value segments. The rainbow design and leprechaun setting capitalize on popular thematic trends (more about themed slots in casino).

Multiple Routes to Bonuses and Utility for the B2B Segment

777 Rainbow Rampage provides several paths to access Free Spins, activate Hold & Spin, or trigger the Rainbow Feature and Gold Toss, minimizing reliance on a single bonus trigger. This structure can be beneficial for operators in markets where the duration and frequency of bonus rounds are seen as competitive factors, allowing for greater customization in retention and promotional campaigns.

The integration of Cash Symbols, multipliers, and fixed prizes in a 777 mechanics slot strikes a balance for portfolios looking to blend familiarity and novelty in the slots vertical, an element significant in negotiations with suppliers and B2B platforms.
