Game Rules


  • All symbols will pay from the left to the right on adjacent reels, starting from the extreme left reel.
  • Rock Vegas is a high volatility game, which means that player rewards are generated less often than usual; however, the opportunity of obtaining large prizes in a short span of time, is higher than average.
  • All symbols will pay from the left to the right, on selected paylines.
  • All wins will be multiplied by the bet per line.
  • Bonus wins will be summed by the total bet.
  • All values will be expressed as actual wins in coins.
  • Only the highest win per line will generate player reward.
  • Gains derived from multiple paylines will be added to the total win.
  • Malfunction voids all pays and plays.


  • The medium paying symbols are represented by the following role players:
  • The Paleolithic / “caveman”;
  • The white tiger;
  • The green dinosaur; and
  • The mammoth.
  • The low paying symbols are depicted by the royal cards (“A”, “K”, “Q” and “J”) along with the number 10.

Bonus Symbol

  • The tumbling rock icon with the word “BONUS” inscribed across it, acts as the Bonus Symbol.
  • The Bonus Symbol may appear upon all reels.
  • The Bonus Symbol may transpire naturally, or by chance at the end of a spin.

Mega Hold & Spin Feature

  • 3 Or more Bonus Symbols are required to trigger the Mega Hold & Spin Feature.
  • This feature will kick off after all winning line sequences are paid.
  • The standard symbols will fade away and a new grid (of 10 x 10 positions) will appear.

    • Each Rock Symbol holds a fixed value, as follows:

  • The round starts with 3 respins.
  • All Rock Symbols appearing after each respin will remain upon the screen until the end of the round.
  • For each time that a minimum of 1 Rock Symbol appears, the amount of respins are recalibrated to 3 rotations.
  • The round will continue until either the respins are exhausted, or all positions on the screen are filled with Rock Symbols.

Cluster Rock Symbols (Hold & Spin Feature)

  • Whenever a rock cluster (of 2 x 2 or 3 x 3) of the same symbol type forms, it will be transformed into a big rock (of that symbol type) and a random Multiplier will be assigned to it.
    • For a 2 x 2 cluster, Multipliers are between x 5 and x 10.
    • For a 3 x 3 cluster, Multipliers are between x 35 and x 500.
    • The Multiplier will apply to the value of all symbols from that cluster.
  • The system may casually add Rock Symbols onto the screen (in any position – with a fire animation) after each respin.

Mini Game Feature (Hold & Spin Feature)

During this feature, a Key Collection Mini Game is presented to the left side of the grid.

  • Rock Symbols depicting Keys (symbols) will fall onto the reels.
  • Key Symbols are collected in a trail
    • 10 Key Symbols are required to obtain a Mystery Multiplier.
  • When at least 3 Key Symbols are collected upon the trail, a chest may randomly open and award the gamer with 1 of the below prizes:
  • Rock Symbols: with its value summed by a random Multiplier (from x 0.50 to x 500);
  • A random Direct Money Award (from x 10 to x 500 the total bet);
  • A random number of Key Symbols (from 4 to 10);
    • These Key Symbols will be added to the trail immediately.
  • A random general Multiplier (from x 2 to x 100); or
    • This will apply to the total gains at the end of the round.
  • 1 Re-trigger.
  • Mystery Multiplier:

Should sufficient Key Symbols be collected to reach this milestone, the gamer will be allocated with a random Multiplier (from x 2 to x 100), which will sum the current attained Multiplier.
