How to Play

When you come to Mars to help Asahi, you will fight in a 5x5 cluster grid where you can win if you collect at least 3 identical symbols adjacent to each other horizontally or vertically. Each winning combo will be removed so that you get new symbols and increase your level and multiplier. Let's start the Robo Ultra slot:

  1. Activate the Robo Ultra machine for real money or in a demo version
  2. Then, place a bet from €0.20 up to €40
  3. Next, click on play to play in the classic version or activate the blitz mode, in which everything happens more quickly
  4. You can also buy the bonus round with your credits

Robo Ultra RTP and Volatility

8 
The Mars Independence War in Robo Ultra will run with an RTP of 96% and medium volatility.
Our opinion is that the payout rates presented are more than optimal to help the Asahi robot win, and this will lead to corresponding rewards according to the paytable. Such parameters will definitely get a rating of 8.

Theme

9.6 

A long time ago, when resources on earth ran out, people went to Mars to find the necessary supplies there. Unfortunately, in addition to engineers, bandits arrived on Mars, so they began to pump out and terrorize local robots. And so the war began. So much time has passed, but the war continues and it's time to protect the robot planet Asahi. In this battle, you can put an end to this battle if you use all the features of the slot. In addition to the plot, we can note the chic presentation, animation, and sound design. We haven't seen such gorgeous slots for a long time, so we'll put a rating of 9.6.

By spinning the cluster reels and using the cascading mechanics, you can catch generous symbols. For example, Tank and Crab pay up to 2x, Jaguar and Big Head up to 3x, Orange, Green, and Purple colours up to 10x, and the mix of medium symbols up to 5x. The wild symbol can replace elements, bring you up to 50x, and open the free spins round.

Bonus Rounds & Free Spins

9.4 

In the Robo Ultra slot by Yolted, you can get a lot of bonus features that you can get thanks to the cascading mechanics. All these features are really interesting and bring generous payouts, so we put a rating of 9.4 and will tell you more about them later.

Multipliers and Special Attacks

Each time you get winning cascades, you increase the multiplier by +1. This way, you can go up to 100x. As soon as your wins are interrupted, the multiplier will be reset to zero. You will also have a chance to trigger special attacks. For example:

  1. Kesagiri – Asahi will draw his swords and swing them diagonally to destroy random symbols that are on the way
  2. Gun Barrage – the robot can take out its blasters and remove a batch of random symbols
  3. Mine Deployment – Asahi can drop multiple Wild Mines at random positions

Second Wave

When you get winning cascades with high symbols, you can fill up the meter and trigger Asahi's special abilities. Five such symbols fill the counter and the robot will use all 3 of its abilities. Also, the multiplier will reset before this feature.

Free Spins Feature

By using the features of the slot, you can access the bonus game. If you remove all symbols and 3 Wilds remain on the grid, you will start a round before which you can choose the number of free spins with unique features. Also, in the bonus game, you can get 50x if you remove all the symbols. In the bonus game, the multipliers will not reset and will accumulate up to 100x, while filling the meter will add additional spins. Let's look at the options for free spins and abilities:

  1. Kesagiri – 10 free spins and a sword feature after each empty spin. You will also get 6 extra spins for the collected counter
  2. Gun Barrage – 8 free spins and a feature with blasters. Two extra spins per collected counter
  3. Mine Deployment – 5 free spins and a Wild feature. Three extra spins per collected counter

Max Win

10 
If you help the Asahi robot fight off all attacks, you can get a reward of up to 20,000x as a max win.
This is a very generous potential, especially considering that the slot has a lot of features that will help you get big payouts. Such a max win deserves the highest rating of 10.

Overall Rating

9.3
The Yolted team surprised us a lot with their release of Robo Ultra. We have not seen such dynamic and interesting slots for a long time. Everything is perfect in the game, including mechanics, bonus features, the max win potential, plot, and graphics. We think this game will definitely be in the top. So we recommend this game, especially if you like not only a beautiful shell but also high-quality mechanics.
