Dungeon of Riches Reinvents Hold & Spin With Expanding Reels

Dungeon of Riches
Posted on July 31, 2026

TaDa Gaming is launching "Dungeon of Riches", an online slot based around a fantasy world with a spin on a popular mechanic. In addition to a Hold & Spin feature, the game will include expanding reels and progressive multipliers; all part of a single feature. According to TaDa Gaming, the game is a 5 x 3 layout with 243 paylines, providing up to 5,000 times bet winnings while guiding the player through their journey to collect treasure and battle monsters.

In terms of New Zealand players, the release of "Dungeon of Riches" fits into a larger trend in the iGaming development space. Instead of just reproducing successful mechanics, developers are improving those mechanics by adding new systems to the game that create incentives for extended play. Hold & Spin has been one of the most recognizable formats in the iGaming space over the last few years; however, it appears that TaDa Gaming has found a way to innovate with that format in "Dungeon of Riches".

Hold & Spin Continues to Evolve

Over recent years, many online slot games have implemented some variation of the Hold & Spin mechanism. Typically, the goal of Hold & Spin is to lock in symbols (or other items) on the screen so that you can get additional spins or jackpot wins. However, since every Hold & Spin round will look the same at first glance to the average player, developers are now faced with the task of developing new approaches to make each bonus round unique. With "Dungeon of Riches," TaDa Gaming takes a different approach.

They use a progressive system, instead of having the entire bonus round be treated as a single event. As the player completes each row of reels in the bonus round, they unlock additional levels in the dungeon and expand vertically - which means each level of completion adds additional multiplier power. Thus, the bonus round becomes a continuous process that provides multiple milestones for the player to work toward, rather than relying solely on achieving one singular outcome.

Progressive Elements Drive Player Engagement

Another innovative element in "Dungeon of Riches" is the expanding reel feature. When entering the bonus round, players start with a three-reel-wide layout. Once they complete the third reel, it expands to four-reels and once again after completing the fourth reel it expands to five reels, and finally when they complete the fifth reel, it expands to six reels. The story behind each expansion is based on defeating monster after monster and going deeper into the dungeon while increasing the strength of their multiplier.

This is another example of a growing trend among high-end online slots. Many developers are now building features that feel like adventures as opposed to single event prize rounds. Players see these as creating more momentum during the feature round.

Multi-Functional Mechanics Create Additional Payout Opportunities

While expanding reels provide an exciting experience for players, the game includes several other connected mechanics. Instant Multiplier symbols increase the value of individual reel values. Additionally, Blue Gem Fill symbols fill entire reels with Cash Prize symbols to initiate fast collections. Finally, Pink Gem Refill symbols add cash prize symbols across the board to facilitate back-to-back collections or even create chain reaction opportunities.

Alongside Mystery Symbols, Wild Substitutions and multiple Cash Prize values (with values ranging from 0.5x to 100x), the game provides many pathways to large payouts. Layered structures such as these have become extremely common with modern online slot games because they maintain dynamic bonus rounds without making the gameplay confusing to understand.

Fantasy Themes Remain Extremely Popular

The game's medieval fantasy environment also represents an ongoing trend in online slot themes. Knights, monsters, treasure chests and magical artifacts continue to represent elements of familiarity to a broad base of gamers internationally and specifically, gamers in New Zealand who frequently access global online casino content. By integrating medieval fantasy with progressive gameplay mechanics, TaDa Gaming has developed an environment that enhances gameplay mechanics as much as it does support the theme. This relationship between theme and gameplay has increased significantly in importance due to growing competition within the online slot market.

Final Thoughts

For New Zealand gamers interested in current developments in online casino gaming, "Dungeon of Riches" exemplifies how established mechanics can still be evolved via thoughtfully designed products. TaDa Gaming has integrated traditional Hold & Spin style gameplay with expanding reels, progressive multipliers and an interlocking progression system that encourages continued success throughout the bonus feature. Furthermore, "Dungeon of Riches" also illustrates a greater trend in the iGaming industry. The trend involves developers refining well-proven concepts using new ideas that enhance gameplay experiences. By incorporating progression, visual narrative techniques and interconnected bonus mechanisms, "Dungeon of Riches" presents a unique take on one of iGaming's most enduring formats.
