Be part of the action as you spin the reels of this fantastic online slot game by Elk Studios. Sumo Sumo is an adrenaline-pumping game that takes you to the land of the rising sun. We had enjoyed Elk Studios games before, like, Coba, Cygnus, and Taco Brothers Derailed. This time, you will have the time of your life facing some of the famous wrestlers of Japan. Sumo wrestling is both a sport and a religious ritual in Japan. No wonder it is very popular in the country and the whole world.

Sumo Sumo has high volatility, making it challenging, especially for those new to online slot games. Elk Studios has a high max win potential for this game, 25,000x. However, the RTP is lower than the other online slot machines.

Sumo Sumo – Gameplay

Sumo Sumo is played on five reels and rows, with 259 ways to win. Players may place their bets starting from 0.20 to 100. Like in many online slot real money games, a win is formed if you can land at least three identical symbols on a payline. The symbols on the reels are also unique and exciting. Starting with the low-paying symbols, cherries, grapes, lemon, and watermelon. Landing five of the same symbols pays between 0.5x to 2x of the stake.

On the other hand, the higher-paying symbols are the blue and red Sumo wrestlers. Landing five of the same symbol pays between 5x, and 10x the total played bet size. Special symbols like the red W, which is the wild symbol, may also land. The scatter symbol is the tile with the “Free Spins” written. Let us see what other features Sumo Sumo has.

Sumo Sumo – Bonus features

The bonus features of Sumo Sumo are the Wild Symbols, Wild Sumo Stack, Speedboat Bonus, and the X-iter.

  • Wild symbols – the symbols replace the regular paying symbols to help form the winning combinations.
  • Wild Sumo Stack – the Sumo symbols stacked on each other act as the walking wild multiplier. The number of Sumo wrestlers on the stack corresponds to the multiplier value. If you land several Wild Sumo Stacks, the values are multiplied before being applied to the win. Players are given a respin when a stack is created, and the stack moves a step to the right. Once the stack reaches the rightmost reel, they move to the left. The respin ends when there is no Wild Sumo Stack added.
  • Speedboat Bonus – this feature is triggered when three Speedboat Bonus symbols land. Players are given three lives on a 5×5 reel setup with a collection feature. The Speedboat symbol that initially lands comes along with an X value. As such, the other positions will spin. A life is lost for every spin, but whenever a symbol or more lands, the lives will reset to three.

The speedboat will run around to collect the value of the symbols that land. Here are the special symbols that may land:

  • Swimmer Sumo Symbol – when this symbol lands, the speedboat will add the value to the swimmer.
  • Wakeboarder Sumo Symbol – the speedboat adds the collected value from the wakeboarder. The counter for the wakeboarder sumo symbol will then be activated. The wakeboarder attaches itself to the speedboat; every position it passes will increase the multiplier. Additionally, the wakeboarder can stack up, and the number of symbols corresponds to the number of positions it passes by.
  • Ramp symbol – the symbol’s value is multiplied by the collected values of the speedboats and wakeboards.
  • Harpoonist symbol – the speedboat will add value to the harpoonist symbol. The harpoonist will increase all uncollected values of the swimmer and wakeboarder. The Turbo Harpoonist symbol may also land to increase the values of the swimmers and wakeboarders before the speedboat collects them. The bonus feature ceases when no more lives are available, and no more values are to be collected.
  • Free spins feature – this bonus feature is activated when two scatter symbols land. Players are then given six free spins, and the Wild Sumo Stack will stay as long as they are on the first reel. The feature can be retriggered.
  • X-iter – this feature is equivalent to the bonus buy feature of other online slot games. Players have the option to purchase several features at a particular cost.
  • 2x (Bonus Hunt) – increase the chances of triggering the speedboat bonus and free spins.
  • 25x (Brawl Mode) – guaranteed Brawl between the sumo wrestlers.
  • 100x (Speedboat Bonus) – speedboat bonus game is triggered.
  • 250x (Super Speedboat Bonus) – the super speedboat bonus game is activated, and every harpoonist is now in turbo mode.
  • 500x (Free spins) – free spins feature is activated.

Sumo Sumo – My verdict

Sumo Sumo is packed with symbols and features that excite the game. Starting with the overall design and soundtrack. These create a fantastic feeling that makes you part of the game itself. The bonus features are impressively entertaining as they boost your potential rewards and add fun, especially when the special symbols land.
