Eternal Clash

Octoplay leans into anime and manga art for its own take on Eternal Clash, pitting cartoonish heroes against a rotating cast of monsters across a 6-reel, 4-row grid with 24 paylines. The base game plays like a fairly conventional slot on the surface — diamond-shaped low-pay symbols in six colourways sit alongside three named characters, Gaia, Arcanos and Crimerra, as the high-value symbols — but the real hook is the Showdown Spins bonus, which turns the reels into a battle rather than a standard free-spins round.

Low-value diamonds pay 2x to 8x the bet for six matching symbols across a payline, while the three character symbols reach 10x to 20x for the same six-of-a-kind result. Two mechanics push the base game beyond simple line wins: Big Symbols form when an entire reel lands stacked with copies of one character, merging into a single oversized symbol that counts as four matches and carries a 2x multiplier on every win it contributes to. Separately, a full-reel Sword Wild can appear across all four rows of a reel, substituting for everything except the scatter and applying its own multiplier of 2x to 5x to any win it completes.

Landing three or more scatters sends the game into Showdown Spins, which opens with 1,000 health points on a shared health bar, plus 500 more for every scatter beyond the third, up to a 2,500-point ceiling. From there, the reels fill with allied characters on the left three positions and enemy characters on the right three, alongside Swords of Power that buff whichever allies are present. Allies alone build attack power over time; enemies alone chip away at the health bar; and when both sides land together, they trade damage based on their attack values until one side is destroyed. Gaia, Arcanos and Crimerra carry 50, 100 and 200 attack power respectively, while the enemy roster scales from the comparatively weak Shadow up to Corruptus, whose 700 attack power pairs with a cash prize as high as 10,000x the bet when destroyed, a tier matched by the tougher Blazethorn. The Swords of Power add flat attack bonuses of their own, and the second and third tiers also attach a 2x or 5x multiplier that applies to whatever cash prize an ally's kill pays out. The round ends when the health bar empties or the win cap is reached.

A Buy Feature sends players straight into Showdown Spins for 250x the bet, at a slightly higher 95.77% RTP than the base game's 95.72%. Octoplay rates the standard volatility at 4 out of 5, and with a hit frequency of 13.30% and a maximum win of 12,000x the stake, Eternal Clash is built to run long stretches of quiet base-game spins before the scatters line up and the battle mechanic takes over. Bets run from 0.10 to 200 per spin. However the Showdown Spins play out, the appeal here rests on watching the health bar swing between allied buffs and enemy damage rather than on any single symbol combination in the base game.
