Los Cuatro Esqueletos Slot by Relax Gaming

This one runs the Dream Drop format on top of a 10-payline Día de los Muertos base, and the headline trick is that the Wild and the Scatter are the same icon. Every Wild that lands also drops into a persistent collection meter, so even dead spins where the wild substitutes for nothing still count toward something bigger.

The base game is a small 5x3 set behind a stage strung with papel picado and warm string lights, with a moonlit adobe street blurred behind the cabinet. Four mariachi calaveras handle the high pays - the lead skeleton matches the Wild's payout exactly, both topping out at 500x for five of a kind. Card royals fill the rest in saturated pink, turquoise, orange and purple. Pinatas pop into view on wins with nine different animations, which is more symbol variety than this format usually bothers with.

Free Spins start at 3+ Scatters and award 10 spins with one expanding special symbol. Normal payline wins resolve first, then the special pays from anywhere on its reel based on how many copies landed - on all 10 lines, even when not connected left-to-right. Wilds are ignored when scoring that expanded symbol, which is unusual and worth knowing before you assume they boost the round.

The collection meter is the real progression layer. 600 collected Scatters trigger Super Free Spins, where you pick TWO expanding symbols via Pick'N'Click before the round starts. Re-triggers add another 10 spins plus another picked symbol, with no cap on stacking - keep re-triggering and eventually every standard symbol becomes an expanding payer. Bet sizing is the weighted average of what you wagered while filling the meter, so cheaper spins during collection drag the trigger bet down. Surplus over 600 carries forward to the next meter.

Sitting on top of all this is the Dream Drop system - six progressive tiers (Rapid, Midi, Maxi, Major, Mega, plus a Daily that must drop three times in fixed 8-hour UTC windows). The Jackpot Spin can hit randomly before any normal spin, replacing the reels with DD symbols and stone blocks. Fill any one reel with DD icons and the matching tier is yours, guaranteed once the spin triggers. The Mega seeds at 1.5 million euro and the Major at 37,500. No buy bonus here, which fits the format - jackpots are the headline, not a feature you shop for. Demo play obviously can't win them.

Win cap is 10,000x, which the free spins rounds can hit on their own and end the round when they do. From Relax Gaming, December 2023.
