Rampage Riches is a monstrous video slot from provider Adoptit Publishing. Developed by Lost World Games, and launched on August 11, 2015; its basis is an ill-fated scientific experiment. Themes: seismology, radioactivity, mutation, Japanese mythology, sci-fi, suboceanic eruption, natural and scientific crises, and tectonic forces.

As per the synopsis of the game formally titled King of Kaiju: Rampage Riches: a 1960s global-scale devastating volcanicity beneath the Pacific Ocean emits a hitherto unidentified rock named virillium. Seven years previously, there had been a chaotic series of more eruptions in the so-called V-Day, prompting cautionary intergovernmental consultation with scientific organizations, particularly the presently world-leading defense contractor Sabretech Research.

Now, Sabretech’s discovery and subsequent monopolistic control and misuse of the energizing virillium rock, dangerous than uranium and plutonium, causes a mutating scientific disaster while experimenting on five extant and extinct “Kaiju” animals—partially robotic ape Allirog; alligator-turned-turtle Giga Shell; three-headed bat-cum-snake avian dragon King Genma; reptilian dinosaur Tyranazoid; and partially robotic gray-and-red cyborg Chronos.

Rampage Riches Game Characteristics

Rampage Riches has wild eruptions, bonus and free games, and 20 fixed winning ways wherein the formation of the ordinary/wild symbol-related three/four/five rightward combinations yield X0.05 to X5.00 payouts.

The Rampage Riches’ pipe-fitted, celled and bricky-and-metallic 5X3 grid has a utopian-turned-dystopian metropolitan setting.

The Rampage Riches’ coins/line: $0.01, $0.02, $0.03, $0.04, $0.05, $0.10, $0.25, $0.50, $1.00, $2.00, $3.00, $4.00, and $5.00. Thirteen total bets: $0.20 (minimum), $0.40, $0.60, $0.80, $1.00, $2.00, $5.00, $10.00, $20.00, $40.00, $60.00, $80.00, and $100.00 (maximum).

Rampage Riches has twelve symbols: three special and nine ordinaries. Special: substituting “wild” magma; flying “bonus” King Genma amid volcanicity; and a green “free spins” Tyranazoid.

Ordinaries: blue reptilian eye; craw mark; mysterious green virillium rock; four-toed reptilian pawprint; and Katsumi font-inspired orange A, orange K, orange-and-red Q, red J, and red 10.
