Aztec adventure slot with Ruby Blaze character, Hold & Earn respins with 4 fixed jackpots, and free spins bonus on a 5x3 grid.


Lost Empire: Featuring Ruby Blaze is Mancala Gaming's take on the jungle adventure slot. Ruby Blaze is the game's branded character - a treasure hunter shown wielding a torch against an Aztec temple backdrop. The 5x3 grid sits inside a stone portal framed by carved statues, with four jackpot meters running across the top.
Ten paylines is modest for a 5x3 layout. That count keeps individual wins more meaningful since winning combinations need to follow specific paths rather than connecting through hundreds of ways. Combined with high volatility, expect stretches of empty spins broken by concentrated payouts.
The respin mechanic triggers when enough special symbols land simultaneously. During the round, you start with three respins. Each new symbol resets the counter back to three. The goal is to fill positions on the grid before respins expire.
Four fixed jackpots sit above the reels: Grand (5,000x), Major (250x), Minor (100x), and Mini (25x). Landing a jackpot symbol during respins awards its value on top of collected coin prizes. The Grand tier at 5,000x accounts for nearly the entire 5,100x max win cap.
Scatter symbols trigger the free spins round. This runs as a separate mode from the Hold & Earn feature, giving the game two distinct bonus paths. The accumulative feature flag is active, meaning certain values or multipliers can build up across the free spins session.
Having both Hold & Earn and free spins in a single slot gives more variety than Mancala's 3x3 jackpot games, which typically only have the respin loop. Ruby Blaze splits its potential between two bonus modes rather than concentrating everything in one.
High-paying symbols include Ruby Blaze herself, an Aztec mask with green stone eyes and a golden crown, a purple treasure chest with gems spilling out, and a ceremonial dagger. Low-pays are card royals (J through A) styled with gold trim and stone textures to match the temple theme.
The art direction leans into blue-green jungle tones with gold accents. Stone carvings flank both sides of the reels. It's a well-worn aesthetic - Aztec/jungle slots are one of the most crowded themes in iGaming - but Mancala's execution is clean. The named character is a differentiator, even if Ruby Blaze doesn't have the brand recognition of a Lara Croft or John Hunter.
Buy bonus costs 42x bet for direct entry to the bonus feature. That's a moderate price point. At 19.75% hit frequency in base game, natural triggers come often enough that the buy option is more of a convenience than a necessity. Players who prefer the Hold & Earn specifically may want to grind it out organically.
