Overview
Gladiators from Endorphina is a 5x3, 21-line video slot with a Roman arena theme flipped underwater, so the fighters are fish gladiators instead of men in armour. The key feature is the free spins round, where selected gladiators turn into sticky Wild wreaths on the next spin and every bonus win gets a flat x2 multiplier. I do not mind the odd theme, but for serious players the old-school maths show quickly.
High volatility is part of the package, yet the headline numbers are not strong enough to back that risk. The verified RTP is 94.76%, and that is below what I want before putting any serious bankroll through a grindy base game. With a proper bankroll, it is playable, but I would class it as a nostalgia slot, not a premium hunting target.
Main symbols
Symbols are straightforward. The Joker Wreath is the Wild and substitutes for everything except the bonus symbol. The highest-paying regular is the fish riding seahorses, which pays 100x the base bet for five of a kind. Next comes the fish with sword and shield, paying 48x for five. Lower symbols are themed card ranks, but the reviews do not give exact values for them.
From a payout perspective, this is not a slot with brutal top-symbol value in the base game. A 100x five-of-a-kind is fine for a 21-line format, though it does not move the ceiling much. I would not chase line hits here. Most of the value sits in the bonus setup, where extra Wild coverage can do the heavy lifting.
Symbol Payouts
Free Spins Explained
Bonus entry is clean. Three or more Shark scatters anywhere trigger Free Games, with 10 free spins for 3, 20 for 4, and 50 for 5. During the feature, all wins are doubled by a x2 multiplier. Free spins can also re-trigger, which matters because the round needs time to build.
After each bonus spin, the game picks a winning gladiator team based on majority on the reels. Those symbols receive laurel wreaths, and the wreaths stay in place for the next free spin as Wilds. If no gladiator lands on that spot in the following spin, the wreath is removed. That makes the bonus volatile in a useful way, because one good setup spin can feed the next.
Bonus Buy Options
Triggered by 3 or more Scatter symbols anywhere. 3 scatters award 10 free spins, 4 award 20, and 5 award 50. All bonus wins are multiplied by x2, and selected gladiator symbols gain laurel wreaths that become Wilds on the next spin.

RTP, volatility and max win
94.76% RTP and high volatility is a rough mix. I can accept savage variance when the top end is big enough, but the cited maximum win is only 2200x. For serious players, that ceiling is too low for this variance. Dead spin frequency in the base game looks like the usual older 21-line profile, plenty of quiet stretches, then the game asks the bonus to bail it out.
Bet range runs from 0.21 to 105, so high-stakes play is technically possible, but maths matter more than stake limits. There is no Bonus Buy mentioned in the reviews, which hurts the slot for bonus hunters because you are forced to sit through the low-RTP base game. The buy is not overpriced here, it simply is not on the table.
