Skulls Heap
A Day of the Dead slot with 4,096 ways, free spins, and multipliers.
GONG Gaming Technologies is an independent slot studio launched in 2020 by gaming veterans with more than two decades of industry experience. The developer built its early reputation through collaboration with Microgaming, producing Pirate's Quest and Skulls Heap before signing an exclusive supply agreement in 2021. GONG's games are often described as math-first: the underlying feature model and win structure receive as much attention as the artwork wrapped around them. That approach has produced a varied catalogue spanning fixed-payline slots, 4,096-way layouts, progressive-style feature meters and the studio's U MAX mechanic, which can dramatically expand the number of possible winning combinations. Themes move from gladiators and Vikings to Day of the Dead imagery, ancient Egypt and the recurring Royal League series, giving the studio recognizable mechanics without forcing every release into the same visual formula.

GONG Gaming Technologies entered the market in 2020, created by a team whose gaming experience predated the new studio by more than 20 years. It first worked with Microgaming on Pirate's Quest and Skulls Heap, then signed an exclusive supply agreement in April 2021. Inferno Gladiator became the first release promoted under that deal, followed by titles that widened the studio's mechanical range, including Viking Queen, Maya U MAX, Piggy Luck and the Royal League series. As Microgaming's distribution business transitioned to Games Global, GONG content continued to circulate through the same broader ecosystem. The catalogue has remained smaller than those of the largest studios, but it has continued beyond its first launch period, with current databases showing later releases alongside the early Microgaming-era games.
GONG's catalogue is built around changing the math model instead of simply repainting the same reels. Skulls Heap uses 4,096 ways, while Inferno Gladiator and Viking Queen rely on fixed paylines and very different free-spin structures. Viking Queen saves base-game shield progress toward a future multiplier, and the U MAX mechanic used in titles such as Maya U MAX can pull symbols from a topper to create as many as 248,832 winning ways. The Royal League line adds another recurring framework with cash bonuses, collection systems, Golden Spins and jackpot features. This variety supports GONG's maths-first reputation: the studio can reuse a broad visual quality standard without making each game behave identically. Exact RTP settings vary by title and sometimes by operator configuration.
GONG signed an exclusive supply agreement with Microgaming after collaborating on early releases. When Microgaming's distribution business moved to Games Global, the same studio catalogue continued through that broader network.
No. Inferno Gladiator and Viking Queen use 25 paylines, while Skulls Heap uses 4,096 ways and the U MAX format can expand to far larger numbers of possible winning combinations.
U MAX uses a special symbol and topper to add symbols to the reel area, increasing the available ways to win. In Maya U MAX, the format can reach up to 248,832 ways.
The studio had already collaborated with Microgaming on Pirate's Quest and Skulls Heap. Those early projects helped establish the relationship before the 2021 exclusive supply agreement.
