Random Runner series: from respins to random wilds
When Random Runner (Greentube) appeared in 2015, Greentube established the Random Runner series around a compact 3x3 fruit-machine format with five paylines, high volatility, respins and a separate bonus game. Its narrow screen and low minimum bet preserve the quick reading of a traditional cabinet while the respin loop supplies the main source of suspense.

Random Runner Super Wild returned to the retro fruit identity in 2025 but changed the feature emphasis. The sequel puts wild symbols, including random or additional wilds, at the center instead of presenting the original respin-and-bonus combination as its defining hook. That makes the line's evolution easy to read: the first game builds tension by repeating reel outcomes, while Super Wild changes the symbol coverage on the grid.
