The fiesta takes place on a standard Megaways game grid, where 6 reels make up the bulk of the panel, with a 4-position horizontal reel located on the top. The number of symbols on the main reels varies from 2 to 7, creating up to 117,649 ways to win at the most.

The RTP is a bit of a crapshoot, with four settings possible depending on jurisdiction. If you're after the most generous version, look for the one with a return value of 96.42%. This one comes with a highly volatile math model and knocks out a hit rate of 35.97%. Here, bets can be set from 20 p/c up to £/€20 per spin on tablets, desktops, or mobile devices.

Winning combinations are formed when matching symbols land in adjacent reels from the leftmost side; any row is fine. Starting things off are low pay card rank tiles, 9-A, awarding 1 to 1.5 times the stake for a six of a kind winning way.

Next come ornately designed band items such as maracas, trumpets, violins, and guitars, which are worth 2 to 50 times the stake for six. The wild symbol pops up to assist players by substituting for any pay symbol. It appears organically on the upper reel, or it can land on the main reels as part of a Sombrero Spin.

Rolling Reels
Rolling Reels remove winning combinations when they hit, and symbols remaining on the reels fall down into the spaces. If new combinations are created as a result, then Rolling Reels roll again.

Special Symbols
As well as being the place where wilds hit, the top reel is also where 4 special symbols appear. Each one awards something different when triggered by a Sombrero Spin:

Piñata – awards a cash prize of 2x, 3x, 5x, or 10x the bet.
Firecracker – turns itself and all symbols below it wild except scatters.
Rocket – turns itself and up to 3 random positions on reels 2-6 into wilds. It does not transform wilds, scatters, or special symbols.

The fourth special symbol is the wheel. Trigger this, and you get one jackpot spin to win the Mini, Minor, Major, or Mega Jackpot, worth fixed amounts of 15x, 50x, 500x, 10,000x the bet, respectively.

Sombrero Spin
In the base game, when special symbols hit, they do not automatically award their prize. Instead, a Sombrero Spin must trigger first, which happens at random. Sombrero Spins highlight positions on the top reel, and if a special symbol lands in a highlighted spot, it is triggered.

Free Spins
Gold bars are scatter symbols, and having 4 of them in view triggers 10 free spins. If more than 4 scatters land, each additional one awards an extra +2 free spins. What changes in free spins is that Sombrero Spins are always active. This means every free spin can technically trigger special symbols.

Feature Buy
As well as activating free spins naturally, they can be bought for direct access to the bonus game. The cost for buying free spins in Dia Del Mariachi Megaways is 80 times the total stake.
