The Achilles slot is one of RTG’s older Trojan War games, and like the rest of that stable it still turns up constantly in US no-deposit free-spins offers, which is probably how you got here. Honest first impression, friend: this one is a decade-plus old and shows it, but it stays popular for a simple reason, the free-spins round triples your wins. It is approachable and medium-paced rather than a high-variance grind, with clean visuals and a straightforward paytable. The catch is the return, so let’s get to it.
What Is the Achilles Slot?
Achilles is a 5-reel, 20-line video slot from RTG (Realtime Gaming), released in 2012 and themed on the Trojan War: Achilles, Helen, shields, ships. It is an approachable classic built around a multiplier-driven free-spins feature rather than modern reel mechanics. You will still find it headlining no-deposit free-spins promotions at RTG-powered casinos, which is the main reason it endures.
RTP, Volatility & Max Win
| Spec | Detail |
|---|---|
| Provider | RTG (Realtime Gaming) |
| Released | 2012 |
| Reels / rows / lines | 5 / 3 / 20 (fixed) |
| RTP | Operator-configurable: 95% default (also ~97% and 91% versions) |
| Volatility | Medium |
| Max win | Around 2,500x your stake (from the tripled free spins) |
| Bet range | $0.20 – $5.00 (from $0.01 per line) |
| Bonus buy | No |
Here is the number to keep in mind. Like other RTG titles, Achilles ships with an operator-configurable RTP. The most-cited default is 95%, which sits a little below the roughly 95.5% to 96% online-slot average, and casinos can run higher versions (around 97%) or lower ones (down to 91%). Nothing on the reels tells you which you are on, so open the in-game info screen before you bet. A small gap in RTP compounds over volume, so for a value-focused player this is the real mark against it. If you want the same Greek theme with a slightly better default, the 2020 Achilles Deluxe runs around 95.7%.
The rest is friendlier. The variance is medium, so the swings stay moderate and sessions last, and the low $5 max bet caps big-money play. The headline payouts do not come from the base game; they come from the free spins.
How It Plays — Features
Base Game & the Doubling Wild
The base game is classic RTG: match symbols left to right across the 20 fixed lines. The Achilles symbol is the wild. It substitutes for every symbol except the scatter, is the top-paying icon on the reels, and doubles the payout of any winning combination it helps complete, so wild-assisted lines pay twice the standard amount.
Two Free-Spins Rounds
This is the draw, and there are actually two of them. Land three or more Troy symbols and you trigger the Troy round: 10 free spins with all wins doubled, and it can re-trigger. Land three or more Achilles symbols and you pick one to reveal the headline Achilles round: 15, 20 or 25 free spins with every win tripled, during which lower symbols can transform into higher-value ones to fatten payouts. That 3x round, stacked across re-triggers, is where the roughly 2,500x ceiling comes from, not a single base-game line.
A Note on the Jackpot
Be clear-eyed here, because the sources do not agree and we will not pretend they do. Some databases list a small random jackpot that can drop at the end of any spin; others describe the original as non-progressive, with the 2020 Achilles Deluxe being the version that clearly added jackpots. Either way, treat any jackpot as a rare, random extra rather than a reason to play. The free spins are the real show.
Who It’s Best For
✓ Good for: players who want an approachable, medium-volatility slot with longer sessions; fans of multiplier-driven free spins; anyone trying it through a no-deposit offer.
✗ Not for: value hunters who care about RTP, since the 95% default is below average; high rollers, because the $5 max bet is low; anyone who wants a modern, feature-loaded game rather than a dated classic.
Final Take: 3.6/5
Achilles is a likeable, approachable classic. The tripled-win free spins are satisfying, the second doubled round adds variety, the doubling wild pays its way in the base game, and medium volatility keeps sessions alive. What holds it back is the math and the age: a below-average 95% default RTP and dated presentation make it a niche pick rather than a go-to. If you enjoy the Greek theme and the multiplier mechanic it is worth a few spins, but for pure value there are higher-RTP RTG titles, and Achilles Deluxe does the same idea slightly better. 3.6/5.
If you found Achilles through a free-spins promo, read the fine print first. These offers typically carry a 30x wagering requirement and a cashout cap, so “free” spins come with strings attached. Our no-deposit casino bonus guide and wagering requirements guide lay out the math. You will find Achilles across RTG casinos including Ignition.
