Rules and Gameplay

The slot exhibits medium-high volatility, offering players a blend of regular and significant wins, and comes with RTP ranges allowing casinos to set the return rate between 85% and 99%.

Bonus Features

The R.U.R. slot incorporates several engaging bonus features designed to enhance the gaming experience:

  • Expanding Wilds: Robot Wilds symbols can substitute for any pay symbols and expand across reels, increasing win potential.
  • Full Reel Multipliers: Achieving matching card symbols across the first 3, 4, or all 5 reels triggers a global win multiplier of 3x, 4x, or 5x respectively.

Although R.U.R. lacks a free spins feature, its unique expanding wilds and multiplier mechanics provide ample opportunities for significant payouts.


R.U.R.’s symbols reflect its robotic theme and are divided into three categories for easy wins and higher payouts:

  • Low-paying symbols: Standard card ranks, offering up to 8x your bet for a set.
  • Mid-paying symbols: Small robot parts, with potential wins up to 32x your stake.
  • High-paying symbols: Stars, robot heads, dynamites, and engines, paying out even for just two matching symbols. Engines are the top-paying symbols, providing a 500x payout for a set of five.


The R.U.R. slot game promises a decent payout structure, with the jackpot standing at a 2,500x maximum win. The RTP variation offered by online casinos ensures a dynamic payout system. Here’s a simplified representation of the payout table for key symbols:
