TaDa Reveals New Hold & Spin with Expanding Reels Feature in Dungeon of Riches

Discover a redefined Lock & Respin bonus and progressive reel expansion

Award-winning TaDa has brought a fresh perspective to one of the industry's most established mechanics in latest release, Dungeon of Riches. The three-row, five-reel expanding grid offers 243 ways to win up to 5,000x in an exciting and innovative prisoner/knight themed adventure

Set in a monster-infested dungeon hiding a golden treasure trove, players help the prisoner defeat his enemies, unlock the dungeons and ultimately earn a knighthood from the King, in a quest that offers progressive reel expansion, evolving multipliers and a unique progression system.

Adding to the airy of mystery, images includes monsters, coins, gemstones, magic potions, a tattered flag Wild and illuminated gates Mystery Symbols. The Wild will substitute for all except Mystery Symbols and coin Cash Prizes. When Mystery symbols land, they will all transform into the same symbol, increasing the chances for a winning payline.

Copper, silver, gold and diamond coin multiplier Cash Prizes hold a substantial range of values from 0.5x for copper; 1x and 1.5x for silver; 2x, 3x, 4x, 5x, 6x, 7x, 8x, 10x, 12x and 15x for gold; and 20x, 25x, 30x, 40x, 50x and 75x to a knightly 100x for the diamond.

During the main game, cash prizes landing on a winning payline of three or more consecutive reels will pay out the sum of all the cash prizes. When six cash prize symbols land anywhere, the bonus Hold & Spin game will trigger.

Switching up gameplay, Dungeon of Riches introduces a new, layered Hold & Spin feature that rewards players with continuous progression rather than a single collection event. The bonus begins with three respins, resetting whenever a new Cash Prize symbol lands. Each reel progresses independently, starting on a 3x5 grid with four locked dungeon levels beneath it.

When a reel is filled with Cash Prize symbols, its accumulated value is multiplied by the reel's current multiplier and one dungeon position below is simultaneously unlocked, triggering a monster-slaying animation. 

Once collected, the reel resets, unlocks the next dungeon level and expands by one row, growing from three to a maximum of seven rows.

Each completed expansion also strengthens the reel. Players earn multiplier upgrades of the Green and Red potions by defeating the Spider and Goblin dungeon monsters and enabling wins to accumulate as the feature progresses.

Instant Multiplier symbols increase individual reel multipliers. Blue gemstone Fill symbols will cover all positions on a reel with Cash Prize symbols, frequently triggering instant payouts, expansions and chain reactions while pink gemstone Refill symbols add extra Cash Prize symbols across the grid, accelerating reel completions and creating opportunities for consecutive collections.

By combining the proven Hold & Spin mechanic with persistent progression, an expanding grid and dynamic multiplier development, Dungeon of Riches offers operators a distinctive addition to their portfolio that balances easy onboarding with genuine gameplay innovation.

Sean Liu, Director of Product Management, TaDa Gaming, commented: ‘Dungeon of Riches showcases how we look to reset established mechanics through fresh ideas. By combining progressive reel expansion, evolving multipliers and multiple collection opportunities, we've created a new Hold & Spin experience that builds momentum throughout the bonus feature.’

Available in over 15 languages with 100+ currency choices, Dungeon of Riches is available to play globally from 23rd July 2026.
