2016 Gladiators by Endorphina is a 5-reel, 21-payline slot with 94.76% RTP, high volatility, a 500x max win, wild symbols, a multiplier, scatters and a free spins round.
Built around a boxing-and-athletics theme, the game asks for patience between hits, so bankroll planning matters more here than on calmer titles.
2016 Gladiators Slot Review — Endorphina
2016 Gladiators is a video slot from Endorphina, released on 5 August 2016 and still listed across a number of online casinos. It runs on a 5-reel, 3-row grid with 21 fixed paylines, carries a 94.76% RTP and a high volatility rating, and caps its top payout at 500x the stake. The core question for anyone eyeing this title is not whether it looks polished — it does, in a sports-competition style — but whether its payout rhythm suits the way you play.
Core Gameplay Experience
The 5-reel, 3-row layout and 21 paylines keep the betting grid compact compared with slots running 40 or more lines, which means each spin resolves quickly and the visible symbol set stays easy to track. Endorphina built the presentation around an athletics-and-boxing arena: boxing gloves, a barbell, a stadium backdrop and an athlete figure sit among the paying symbols, with bright, rainbow-tinted colour work carrying the sense of competition and reward rather than menace.
The pace feels tied to that high-volatility design: symbols land, combinations resolve on the fixed lines, and the visual energy of the sports theme is meant to keep short, quiet stretches between wins from feeling flat. Players used to fast-filling bonus meters on low-volatility slots will notice the difference immediately — the screen looks busy, but the bankroll meter moves less often.
Features and Mechanics
Four mechanics carry the game: wild symbols, a multiplier element, scatter symbols and a free spins round. Wilds substitute for regular paying symbols to complete lines that would otherwise miss, and the multiplier applies on top of qualifying wins, which is the main lever behind the title’s 500x ceiling.
Scatters trigger the free spins round, and the award scales with how many land: three scatters award 10 free games, four award 20, and five award 50, according to the provider’s own game information. The free spins round is where the high volatility shows most clearly — because the base game offers fewer frequent small hits, the free spins trigger carries more of the session’s win potential than it would on a lower-volatility title.
RTP, Volatility and Payout Model
2016 Gladiators pays back a theoretical 94.76% of wagers over the long run and is rated high volatility, meaning the game favours fewer, larger hits over frequent small ones. That RTP sits in the 16th percentile of the 4,483 slots in our catalog with a published RTP, against a catalog median of 96% — a figure on the lower side of what the wider catalog shows, worth factoring in alongside the volatility rating rather than on its own.
In practice, high volatility combined with a 500x cap means sessions can run long without a meaningful hit, and most of the recoverable value sits in the free spins round rather than the base game. Players should size bets to survive that variance rather than chase it.
Long stretches without a win are a realistic outcome on a high-volatility slot like this one, not a sign that anything is wrong with the game. Set a bankroll and a per-spin stake you can sustain through a quiet run, and use demo play to get a feel for the rhythm before wagering real money.

Among Endorphina’s high-volatility, 11-to-50-payline titles, 2016 Gladiators ranks 12th of 13 by RTP — only Akbar & Birbal sits lower in that group. The table shows most of the studio’s comparable releases clustering near 96%, so a player choosing by raw return edge alone has closer alternatives within the same provider; one choosing by theme or feature set may still prefer this title.
Similar Free Spins Slots from Other Studios
| Game | Studio | RTP | Volatility | Max win |
|---|---|---|---|---|
| 10 Fruitata Wins | CT Interactive | 98.2% | High | — |
| Starcasino Bonanza | Pragmatic Play | 96.55% | High | 21,100x |
| Gold of Eldorado | Capecod Gaming | 95.63% | High | 2,000x |
| Fiesta De Toros | Ainsworth | 95.778% | Low | 16,666x |
The ceiling gap is the headline here: Starcasino Bonanza and Fiesta De Toros both reach five-figure multipliers, while 2016 Gladiators tops out at 500x — a much smaller swing for the same bet size. A player drawn to this theme but wanting a higher-ceiling outcome would look at those two first; one who prefers a compact, quick-resolving line structure is better served by 2016 Gladiators.
This title suits players who enjoy a themed, fast-paced spin cycle and accept that the free spins round, not the base game, carries most of the win potential. It is not a fit for anyone chasing frequent small wins or a high payout ceiling — both the RTP and the 500x cap sit below what several comparable high-volatility slots offer.
How to Play 2016 Gladiators Online
Demo mode is a practical way to learn the free spins trigger and the pace of the base game before wagering, since no money is at risk while you check how often the scatter symbols appear. The full slots directory carries a free-play option for this and comparable titles. Endorphina games run at a number of casinos as of 2026, including brands such as Golden Star, Cashy and SpinCrypto, and the provider’s catalogue can be browsed through the Endorphina slots hub. Readers interested in the sports presentation specifically can also look at the sports-themed slots for other titles built around a similar visual idea.
Conclusion
“A compact, high-volatility sports slot where the free spins round does the heavy lifting and the ceiling stays modest.”
For players who like a themed, quick-spinning high-volatility slot and are comfortable with a 94.76% RTP that sits below the median of the wider catalog, 2016 Gladiators delivers a focused, if unspectacular, experience. Those prioritising a higher payout ceiling or a return closer to the catalog norm have more competitive options both within Endorphina’s own lineup and among comparable titles from other studios.
