How to Play

Legendary Sumo has a 5x3 layout with 21 paylines and only 2 game modes, that are very simple to understand, and we will cover them in more detail below. So as you see, it's very easy to play Legendary Sumo, and this is what you need to do after you have launched the slot:

  • The first thing to do is to adjust your settings which you can do by clicking on the triple bar icon that's located next to the reels. Here, you can change language, adjust music, turn on some features like “reality check” and others
  • Set your stake and alter how many paylines you want by clicking on them - the paylines vary from 1 to 21, and the stake is €0.01 minimum and €21 maximum
  • Make sure to read about the rules of the gameplay and find out how much symbols are worth - for that click the “i” button on top of the screen
  • Ready to play? Then hit the autospin, or spin button and good luck!

Legendary Sumo RTP and Volatility

8.8 

Legendary Sumo is a medium volatility slot that has an RTP in the range of 95.74% to 96.08%.

This online slot has a very good volatility range - medium - and that means that the game has a good balance between how often you get a winning symbol combination (the risk of losing is lower than in high volatility slots) and how big of a value the symbols have (worth more than in games with low volatility). Now the Return to Player rate of Legendary Sumo is variable, and depending on the casino you can get an RTP in the range of 95.74% to 96.08%. The latter is a decent percentage, which is average for many online slots, but 95.74% is a bit low.

Theme

8.8 

We absolutely love the well-done design of Legendary Sumo, with its food details and vivid colours. Both the symbols and reels, as well as the background are very beautiful and do a very good job of immersing you in the Asian aesthetics of this online slot. In the background there is lovely scenery of the arena, with some houses and a pretty night sky, the reels are made of wood and the gameplay is accompanied by intense, traditional music. For the vibe alone, Legendary Sumo definitely earns an A from us!

Now for the symbols: the game has them divided into regular ones that simply provide payoff and unique symbols with special properties. Regular symbols on Legendary Sumo are 10, J, Q, K, and A - these have the low-value. More valuable symbols are 5 Rikishis (sumo wrestlers).

Unique symbols here are Wild and Scatter: Wild is a red dragon, and, like always, it will substitute for all other symbols except the Scatter, to give more valuable prizes. Now Scatter looks like a golden cup and will activate the Free Games with the Dynamic Sticky Wild feature if you collect 3 or more of these symbols.

7.8 

Free Spins

This feature will be triggered when you collect three or more Scatter symbols. Specifically, 3 Scatters will give 10 free games, 4 will give 20 and for 5 Scatters you will get 50 free spins.

After every free spin, aka free game, a winning Sumo fighters team will be determined. The fighters that are in the majority on the reels will win the round. Moreover, every sumo fighter in the winning team will be awarded a golden trophy that will make him a Wild. So during the next spins, any fighters that stop in the same position as the trophy will inherit the trophy and the Wild’s function.

Risk Game (Gamble)

If you have played Endorphina slots in the past, you probably already know how the Gamble feature works. In it, you will have to choose 1 out of 4 cards and the goal is to beat the card of the dealer. If you do that, your winnings will be doubled and you can try that again up to 10 attempts total. If the lock is not on your side and the dealer wins - you will lose your winnings.

Max Win

7.1 

The top win in the Legendary Sumo is 1,500x your total stake.

In the Legendary Sumo slot, you can win 1,500x/bet and for a medium volatility slot with decent RTP, this is an average and fine potential. Granted, there is no jackpot or Bonus Buy that would have increased the winning chances or given you a big payoff, but there is a Gamble feature to help you multiply the win, as well as up to 50 free games with doubled wins.

Overall Rating

8.1
Overall, Legendary Sumo is a sweet-looking game with appealing visuals, smooth mechanics and good features. The Wilds spice up the base game and the Scatters take the game to the next level with the Free Games. We would recommend for many players give this lovely title a go. Especially, we think that Legendary Sumo will be a good choice for casual players, given the medium volatility, average max win and relatively simple gameplay.
