TaDa Rewrites the Bonus Rule Book with 777 Rainbow Rampage

Feature-packed 777 slot combines Wilds, Cash Coins, Free Spins and Hold & Spin action with a leprechaun twist

Award-winning TaDa Gaming is helping players find a spectacular pot of gold in new release, 777 Rainbow Rampage. The five-reel, three-row, 25-payline slot combines instantly recognisable 777-style gameplay with an action-packed collection of Wilds, Cash Coins, Free Spins, Jackpots and Hold & Spin features, all wrapped in a colourful leprechaun and rainbow adventure.

Three different lucky 7 symbols represent single, double and triple 7s. Appearing on all reels in both the base game and Free Spins, three or more matching ‘7’ symbols create a winning combination, while mixed ‘7’ combinations will pay at a lower value.

Leprechaun Wilds can substitute for all symbols except Bonus and Cash Symbols. When a Wild lands, it expands vertically to cover the entire reel, creating additional opportunities to form winning combinations.

The Bonus symbol, depicted as a rainbow shooting from a pot of gold, appears only in the base game. Landing three or more Bonus symbols triggers Free Spins, with three Bonus symbols awarding eight spins, four giving 10 and five for 12.

During Free Spins, Wilds automatically become powerful Wild Collect Symbols. When Cash Symbols land on the same reel as a Wild Collect Symbol, their values are collected and the Wild Collect multiplier for 2x, 3x, 5x or 10x is applied to the total Cash value. 

When a winning line passes through multiple expanded Wild Collect Symbols, then their multipliers are added together, creating the potential for even bigger wins.

And giving another twist to the gameplay, Cash Symbols with values from 0.5x to 10x the player's bet can land on all reels in both the base game and Free Spins, while four Jackpot Coins offer fixed prizes for Mini (15x), Minor (50x), Major (250x) and Grand at 1,000x.

Landing six or more Cash Symbols triggers the Hold & Spin feature, which can occur in both the base game and Free Spins.

The triggering Cash Symbols merge into a single Coin before the feature begins with three free spins. Each time a new Coin lands, the counter resets to three, allowing the feature to continue as long as new Cash Symbols keep appearing.

Keeping players on high alert, three special Modifier Coins can also land during Hold & Spin, each offering a different way to increase Cash values.

The green ‘Collect’ coin sweeps up all Cash values on the reels, while the blue ‘Add to All’ coin lands with its own Cash value and adds that amount to every other Cash coin. The red ‘Double Up’ coin randomly selects two, three, four or five coins and doubles their values.

When a reel is filled with Cash Symbols during Hold & Spin, their combined value will fly into the separate Pot of Gold beside the reels, adding another layer of prize potential through randomly triggering the Rainbow Feature, upgrading eligible Wilds into powerful Wild Collect Symbols; or triggering the Leprechaun's Gold Toss which sends a random selection of Cash Symbols back on to random positions on the reels. 

In the base game, if the Rainbow Feature is randomly triggered, Wilds can also be upgraded into Wild Collect Symbols, adding another opportunity to collect Cash values.

And, as the Leprechaun's Gold Toss can randomly trigger in the base game too, the extra Cash Symbols can deliver the six or more Cash Symbols needed to trigger Hold & Spin, giving players another route into the feature.

For players looking to increase their opportunities to enter Free Spins, an optional Boost Play mode increases the chance of triggering the round. So, with multiple ways to move from the base game into Free Spins, Hold & Spin or to trigger the Rainbow Feature, 777 Rainbow Rampage builds anticipation throughout the gameplay rather than relying on a single bonus route.

Sean Liu, Director of Product Management, TaDa Gaming, said: ‘777 Rainbow Rampage gives players familiar 777 gameplay but enhanced with expanding Wilds, Rainbow upgrades, Cash collection, four Jackpot levels, Modifier Coins, Free Spins and Hold & Spin action. These multiple ways to win means every spin can potentially turn into something much bigger for the ultimate in anticipation and exciting play.’

With over 15 languages and 100+ currency choices, 777 Rainbow Rampage is available to play from September 16th 2026.
