Which offer is better value?

MexoMax! uses MultiMAX™ — six columns each carry their own multiplier, and active reel multipliers combine by multiplication when they share a win. Raptor DoubleMax uses DoubleMax™ — one global multiplier doubles after every cascade. Both mechanics never reset during Free Spins. The two games differ in max win, RTP structure, grid format, and retrigger availability.

MexoMax! — Read Before Using MEX100

MexoMax! is a Yggdrasil in-house slot released July 28, 2022. It uses MultiMAX™ — a per-reel multiplier system that differs entirely from the DoubleMax™ mechanic in Raptor DoubleMax. The default RTP is 96%, but operators can set lower versions (94%, 90.5%, 86%). Check the active RTP in the Casino Adrenaline game info panel before spinning.

Cluster Pays — How Wins Form

MexoMax! uses a 6×6 grid with no paylines. Five or more identical symbols connected horizontally or vertically form a win. Position on the grid does not affect the outcome — only cluster size matters. Winning symbols disappear and new ones fall from above. Further clusters within the same spin trigger additional cascades.

MultiMAX™ — Per-Reel Multipliers

Each of the 6 columns carries its own multiplier, starting at 0×. Each cascade places one Wild on the grid. The column where that Wild lands increases its multiplier by +1×. When a winning cluster covers symbols from two or more columns with active multipliers, those multipliers multiply together — not add. Two columns at 3× and 4× produce a 12× combined multiplier. Three columns at 3×, 4×, and 5× produce 60×. In the base game, all column multipliers reset on a non-winning spin. In Free Spins, all column multipliers persist for the entire round without resetting.

Treasure Chest

The Treasure Chest lands on the rightmost reel. In the base game it awards one of: an instant cash win of 5×–100× the bet, free spins, or +4 Wilds. In Free Spins it awards one of: +1 spin, +4 Wilds, +1× added to all active column multipliers, or an instant cash win.

Free Spins and the Gamble Decision

Four Scatters award 8 Free Spins. Five award 12. Six award 18. Landing 3 or more additional Scatters during Free Spins adds +4 spins — the feature can retrigger. All column multipliers carry forward across every spin in the round. Before the round begins (unless 18 spins were triggered), a Gamble feature offers to increase the spin count: 8 spins may be risked for 12, and 12 for 18. Each gamble is 50/50. Losing the gamble forfeits all spins entirely.

Raptor DoubleMax — Read Before Using 50RAPTOR

Raptor DoubleMax is a Yggdrasil in-house slot released August 2021. It uses DoubleMax™ — one global multiplier that doubles after every cascade. The RTP is fixed at 96.01%. No operator can adjust it. This makes Raptor DoubleMax the safer RTP choice between the two bonus games.

DoubleMax™ — The Global Multiplier

The multiplier starts at 1× on every spin. Each cascade win doubles it: 1× → 2× → 4× → 8× → 16× → 32× → 64× → 128×. In the base game the multiplier resets to 1× after any non-winning spin. In Free Spins it never resets — each cascade carries the multiplier forward from where the previous spin ended. After every cascade, one Wild lands in a random empty position. This Wild can extend the cascade chain and push the multiplier higher. The 20,000× max win requires extreme multiplier levels sustained across multiple spins in the bonus round.

Free Spins and the Gamble Decision

Three Scatters award 7 Free Spins. Four award 10. Five award 13. Before the round begins, a Gamble feature activates (unless 13 spins were triggered): 7 spins may be risked for 10, and 10 for 13. Each gamble is 50/50. Losing forfeits all spins. Free Spins cannot retrigger — each bonus session ends after the final spin.

About Yggdrasil Gaming

Yggdrasil Gaming was founded in 2013 in Sweden by Fredrik Elmqvist, who previously served as CEO of NetEnt. The studio is headquartered in Malta. Yggdrasil holds licences from the Malta Gaming Authority, UK Gambling Commission, Sweden's Spelinspektionen, Gibraltar, and Romania. Evolution Group acquired Yggdrasil in 2021. The studio continues to operate its own content pipeline and partner programs independently. Every Yggdrasil title uses an independently certified RNG.

Yggdrasil developed a set of proprietary mechanics called Game Engagement Mechanics (GEMs). MultiMAX™, DoubleMax™, Gigablox™, and Splitz™ are all Yggdrasil GEMs. The studio licenses these mechanics to partner studios through the YGG Masters program. Partner studios build and publish via Yggdrasil's GATI (Game Adaptation Tools & Interface) platform, which handles compliance, certification, and operator distribution. MexoMax! and Raptor DoubleMax are both Yggdrasil in-house titles — neither is a YGG Masters release. All Yggdrasil titles at Casino Adrenaline support Bitcoin and crypto deposits.

Key facts:
  • Founded 2013, Malta: Founder Fredrik Elmqvist (former NetEnt CEO). Acquired by Evolution Group 2021.
  • MGA + UKGC licensed: Active licences in Sweden, Gibraltar, Romania, and other jurisdictions. RNG independently audited on every title.
  • GEMs: MultiMAX™, DoubleMax™, Gigablox™, and Splitz™ — Yggdrasil-owned mechanics used in-house and licensed to YGG Masters partners.
  • YGG Masters program: Independent studios publish via Yggdrasil's GATI platform. Both bonus games are in-house Yggdrasil titles, not YGG Masters releases.
  • iSENSE 2.0: HTML5 framework — all titles run in-browser on iOS, Android, and desktop without downloads.

MultiMAX™ vs DoubleMax™ — Two Different Mechanics

MultiMAX™ and DoubleMax™ are both Yggdrasil GEMs built on cascading wins. They build multipliers in different ways. Both persist through Free Spins without resetting.

MultiMAX™ — MexoMax!

Six columns each carry their own multiplier. Each cascade adds +1× to the column where the Wild landed. When a cluster win covers symbols from multiple columns with active multipliers, those column values multiply together. Columns at 2×, 3×, and 5× produce a combined 30× on a shared win — not 10×. In Free Spins, every column multiplier carries forward from spin to spin. A column that reached 4× in spin 2 still reads 4× at the start of spin 3.

DoubleMax™ — Raptor DoubleMax

One multiplier applies to the entire game. It starts at 1× and doubles with every cascade: 1× → 2× → 4× → 8× → 16× → 32×. In the base game it resets to 1× after a non-winning spin. In Free Spins it carries forward. A session that reached 16× in spin 3 starts spin 4 at 16× — the next cascade takes it to 32×. The 20,000× max win requires extreme levels sustained across chained cascades in the bonus round.

Key Practical Difference

Raptor DoubleMax reaches higher single-multiplier values faster through exponential doubling. MexoMax! builds multiplier value across multiple columns simultaneously — six independent accumulators can run in parallel. MexoMax! can also retrigger Free Spins, extending the round and giving column multipliers more time to compound. Raptor DoubleMax cannot retrigger.
