Treasure Sparks by RTG / SpinLogic takes players into a colourful world of Chinese fortune and prosperity. Cai Shen, the God of Wealth, appears alongside golden coins, red lanterns, fireworks, and traditional symbols. However, the real attraction comes from three different Collector features that lead into exciting Hold & Spin bonus rounds.

The game uses 5 reels, 3 rows, and 25 fixed paylines. Winning combinations are formed by matching symbols from the leftmost reel towards the right. Cai Shen acts as the Wild and substitutes for all regular symbols except the Scatter symbols.

The game's three coloured Scatters are central to the bonus mechanics. Green, Blue, and Purple Scatters each work with their own Collector. As more Scatters are collected, the chance of activating the corresponding Hold & Spin feature increases.

This gives Treasure Sparks a different approach to triggering bonuses. Instead of relying on one Scatter combination for a single Free Spins round, the three Collectors gradually build towards separate bonus features.

The Mystic Spark feature is connected to the Green Scatter. When activated, it creates a 5x3 Hold & Spin board with three initial re-spins. The triggering Scatter becomes a Coin, retaining its multiplier value. New Coins lock into position when they land, while each new Coin resets the re-spin counter to three.

Mystic Spark can also introduce random multiplier boosts during the feature. These can increase the value attached to collected Coins or improve jackpot prizes, giving the feature an extra element of unpredictability.

The Extra Sparks feature uses the Purple Scatter and follows a similar Hold & Spin format. However, players begin with four re-spins rather than three. This extra starting spin gives more opportunity to fill the 5x3 board with valuable Coins.

Then there is Twin Boost, which is triggered by the Blue Scatter. This is arguably the most distinctive of the three features because it creates two separate 5x3 gameboards. Each board has its own three-respin counter, so a new Coin resets the counter only on the board where it lands.

Each Coin can reveal a multiplier or one of several jackpot prizes. The available jackpots include Mini, Minor, Major, and Grand. The Mini is worth 10x the bet, the Minor 25x, and the Major 50x. Filling an entire board with Coins awards the Grand Jackpot, valued at 500x the bet.

Twin Boost therefore provides the possibility of completing two boards independently. Filling both boards can result in two Grand Jackpots, making this feature particularly exciting when the reels begin filling with Coins.

Another interesting aspect is that more than one Collector feature can be triggered at the same time. This means a single spin can potentially lead to multiple Hold & Spin modes, adding considerably more variety to the bonus experience.

Treasure Sparks also includes a Buy Feature on supported versions. Players can choose a specific Collector feature and purchase access to its triggering spin. Extra Sparks guarantees a Purple Scatter, Mystic Spark guarantees a Green Scatter, while Twin Boost guarantees a Blue Scatter. An all-in option can activate all three features by guaranteeing one Scatter of each colour.

With medium volatility, 25 paylines, and a top award of up to 50,000x the bet per line, Treasure Sparks offers substantial winning potential alongside its colourful Asian-inspired theme.

Overall, Treasure Sparks stands out because it gives the traditional Hold & Spin concept three different variations. Mystic Spark can boost Coin values, Extra Sparks provides an additional starting re-spin, and Twin Boost doubles the gameboards. Add four jackpot levels and the possibility of triggering multiple features together, and there is plenty to keep the reels interesting.

If you enjoy Coin-collecting slots and Hold & Win-style bonuses, Treasure Sparks offers a particularly feature-rich version of the format.
