RTP Robo Ultra by Yolted is a grid slot with five reels, medium volatility and RTP settings of 90%, 94% or 96%. The game uses a science-fiction theme centred on a conflict between Mars and Earth, with the action built around mechanical combat and resistance forces. Stakes range from 0.01 to 200, and the game advertises a maximum win of 20,000x.
Key features include a bonus game where players choose between three weapons — Gun, Sword or Bombs — which shape how the round unfolds. Robo Ultra also offers up to 100 free spins, with a multiplier that can build to 100x during the feature. A bonus buy option is included for players who want to access the free spins directly.
The demo version is available to play for free, allowing users to review the mechanics and bonus rounds before playing for real money. This format is useful for learning how the weapon choice system, free spin feature and multiplier progression work in practice.
