Yggdrasil is launching the ‘of the Underworld’ slot series, and the first game is Champion of the Underworld. They have released similar games before but not with this exact title. The game features random Wild Fights in the base game and a dynamic grid with Gigablox symbols. The 6×4 reel setup with 4,096 ways to win is a signature of this developer. The game has a cartoonish underworld theme with a massive arena where monstrous creatures battle with Hades. The game’s potential is 10,000x, making it worth trying out.<br><br>In the game, Gigablox symbols up to the size of 4×4 appear on each spin and are divided into regular 1×1-sized symbols if they are part of a win. The four demon-like premium symbols pay between 1 and 2 times your stake for 6 of a kind wins. The Skull Wild is a part of the pay symbols that helps complete wins. The Wild Fight feature appears randomly in the base game, and Hades fights any premium symbol in sight. If Hades wins, the symbols turn wild, including Gigablox symbols.<br><br>To trigger the Bonus Round, you need at least five scatters on the same spin. Each triggering scatter grants +1 free spin, and you can gamble for up to 20 free spins. The gamble feature is a sword pick game with two levels, and losing could cost you the entire bonus round. The Wild Fight feature appears on every bonus round spin, and the win multiplier increases by +1 each time Hades wins.<br><br>Non-UK players and eligible players can use the Bonus Buy option, paying 90x your stake for 5 free spins or 1,000x your stake for 20 starting free spins. <br><br>Champion of the Underworld has engaging visuals and a unique concept, with monstrous creatures fighting in a tournament-style underworld. However, the repetitive soundtrack can be a drawback. The bonus round is diverse, and starting with more spins is advantageous for increasing the multiplier. The game has a decent 10,000x potential and is a good addition to the Gigablox/Wild Fight series.<br><br>Three other games to check out from Yggdrasil are Of Sabers and Monsters, Hades Gigablox, and Monsters vs Gigablox. These games also offer a unique gaming experience with different gameplay mechanics and potential payouts.
