Rich Wilde and the Shield of Athena — Slot Review
The fifth Wilde expedition runs a 5×3 grid with 10 fixed paylines, 96.25% default RTP, and a 10/10 volatility rating from Play'n GO themselves. The Medusa Re-Spin can fire on any spin in the base game, and Cat Wilde joins her father here for the first time.

Play Free DemoQuick verdict
High-risk Greek mythology slot with a brutal base game and explosive bonus potential — bonuses trigger roughly every 73 spins, but the 10,000× ceiling is double what most Rich Wilde titles offer.
Released 28 May 2020, Shield of Athena returns Play'n GO to its Book of Dead-style roots after the cluster experiments of Tome of Madness. The math is brutal — bonuses land roughly once every 73 spins on community-tracked data, and the base game can run dry for 200 spins or more. The reward for sitting through that variance is a 10,000× ceiling, double what most Rich Wilde titles offer. This page covers the mechanics, the RTP versions you should check before playing, and how the slot stacks up against the original Book of Dead.
Three mechanics that drive the win potential
Medusa Re-Spin
When a Shield of Athena symbol turns Wild on the reels — which can happen on any spin, win or lose — it locks in place and triggers a re-spin. Any winning combinations also stay locked. New shields and wins extend the chain. The re-spin sequence ends only when no new locks appear, then everything pays out at once.
Medusa's Gaze Free Spins
Three, four, or five Cat Wilde scatters award 10, 12, or 15 free spins. The Medusa Re-Spin stays active for the entire bonus, so every Shield that lands triggers locks and respins inside the free spin round. Re-triggers are unlimited up to a hard cap of 100 free spins.
Wild Shield doubles the value
When a Shield turns Wild, its symbol payout doubles. Five Wild Shields on a payline pay 1,000× the stake, against 500× for five regular Shields. During Re-Spins, every Rich Wilde wild also converts into a Shield — which is how the 10,000× ceiling is actually reached, by stacking Wild Shields across the grid.
Shield of Athena RTP — three versions, one default
The default RTP is 96.25%, certified by Play'n GO and confirmed by every major review site. What most reviews don't tell you: this slot ships with two lower variants — 94.25% and 91.25% — that operators can deploy at their discretion. Always check the in-game paytable before placing real-money bets.
How to verify which version you are playing: open the slot, click the info button in the bottom-left corner, scroll to the last page of the paytable. The active RTP is printed there explicitly. If a casino's version shows 91.25% rather than the default 96.25%, the difference is real money. Over 1,000 spins at $1 stake, you give up roughly $50 in expected return. Over a 5,000-spin season, that becomes $250. Most regulated EU operators run the default 96.25% — Mostbet, the partner linked here, runs the default version per the in-game info panel. Operators that switch to lower variants are usually smaller offshore brands optimizing for margin.
RTP is theoretical. It assumes infinite spins. In any single session of 200 or 500 or 1,000 spins, your actual return will swing wildly above or below 96.25% — that is what 10/10 volatility means in practice. Slot Tracker has logged 72,216 community spins on this slot and the running RTP currently sits at 464.15%, distorted by a few users who hit large bonuses. The same data shows the maximum win recorded so far is $105,525, which is well below the 1,000,000 ceiling at $100 stake. Treat the published RTP as a long-run anchor, not a session expectation.
Free spins: how many, how often, how to retrigger
The Medusa's Gaze Free Spins round is the only proper bonus in this slot. Three Cat Wilde scatters anywhere on the reels award 10 free spins. Four scatters give 12. Five give 15 — though that's rare enough that most sessions never see it. The headline feature: the Medusa Re-Spin stays active for the entire bonus, so every Shield that lands during a free spin triggers locks and respins inside the round. Re-triggers work the same way as the initial trigger — three or more Cat Wilde scatters during a free spin add another 10/12/15 spins on top. The only ceiling is the hard cap at 100 total free spins (set by Play'n GO at the math model level). In community-tracked data, the average return from one Medusa's Gaze trigger is 53.85× the stake. That sounds modest until you remember the math: at 1.38% trigger rate and an average 53.85× payout, the bonus alone contributes about 0.74× to long-run RTP. The base game and the random Medusa Re-Spin together fill in the remaining 95.51%.
There is no Bonus Buy
Some affiliate sites claim Shield of Athena offers a buy-feature option. It does not. Play'n GO did not include a Bonus Buy mechanic in this slot — confirmed by the in-game info panel and by the GMBLRS specs database (which lists "Feature Buy: No" explicitly). If a casino displays a buy button on this slot, the button belongs to the casino's own promotional system, not to Play'n GO's math model. The Medusa's Gaze Free Spins can only be triggered organically, by landing 3+ Cat Wilde scatters during normal play. At 1.38% trigger rate, that's roughly one bonus every 73 spins on average.
How to play Shield of Athena
Set your stake
Use the plus and minus controls below the reels to pick a bet between $0.10 and $100 per spin. There are 21 stake levels in total. Paylines are fixed at 10 — you cannot deactivate any of them, unlike in Book of Dead.
Check the RTP version
Click the info button in the bottom-left corner and find the paytable. Play'n GO ships this slot in three RTP versions: 96.25% (default), 94.25%, and 91.25%. Some operators run the lower ones to reduce their payout liability.
Spin or autoplay
Hit the green spin button manually, or open the autoplay menu (orange button) for 10, 20, 50, 75, or 100 automatic spins. Autoplay can stop on any single win, on a free spin trigger, or when your balance moves by a chosen amount.
Watch for the Shield
When a Shield of Athena symbol lands and turns Wild, the Medusa Re-Spin triggers immediately. The shield locks in place along with any winning combinations. The reels respin around the locked positions and the chain continues until no new wins land.
Three Cat Wildes for free spins
Three or more Cat Wilde scatters anywhere on the reels trigger 10, 12, or 15 Medusa's Gaze Free Spins. During the bonus, the Re-Spin feature stays active permanently. Re-triggers stack up to 100 spins total.
Simulated test session
We ran a Monte Carlo simulation of 200 spins at $1 stake using the published 96.25% RTP and 1.38% bonus hit rate. Results from a single trajectory (your real session will vary):
Simulated session for illustration only. Real sessions diverge — the slot's 10/10 volatility means individual results swing wide of the mathematical expectation.
How long will your bankroll last?
Enter your starting budget and per-spin stake. The calculator estimates how many spins you can run before exhausting the bankroll, the expected loss at the 96.25% RTP, and the probability of hitting at least one bonus during that session.
Estimates based on 96.25% RTP, 1.38% bonus hit rate, and 600 spins per hour pacing. Actual results vary with volatility.
Five practical decisions before you spin
Always confirm the RTP version
The 5-percentage-point gap between 96.25% and 91.25% costs you $50 per 1,000 spins at $1 stake. That's $1 every 20 spins. Over a typical 90-minute session of 600 spins, you give up $30 in expected return for nothing. Open the paytable info screen before depositing — if the casino runs anything below 96.00%, find another casino.
Plan for 300+ spins minimum
The bonus hit rate is 1/72.5. The probability of seeing zero bonuses across 200 spins is (71.5/72.5)^200, which works out to about 6.3%. Across 100 spins it's 25%. If you only have a 100-spin budget and the bonus does not trigger, you almost certainly walk away down. A 300-spin floor cuts the dry-run probability to under 2% and gives the math a chance to work.
Pick stakes that survive 200 dead spins
Volatility this high needs ammunition. A practical rule: divide your total session bankroll by 200 and use that as your spin stake. With $200 to play, that's $1 per spin. With $50, drop to $0.20. The slotcatalog reviewer documented zero bonus triggers across the first 200 spins of their test session — that's not unusual at 10/10 volatility, and your bankroll has to absorb it.
Don't chase a bonus that just hit
Bonus rounds are independent events. A Medusa's Gaze trigger does not change the probability of the next one. Some sessions deliver two bonuses in 50 spins; others deliver none in 400. The temptation after a small bonus win is to keep stake elevated chasing the next one. The math says nothing has changed. Lock in profit instead — set a hard rule like "after any bonus, I cash out 50% before continuing."
Use autoplay loss limits
Play'n GO's autoplay menu accepts a balance-decrease stop. Set it to 30–40% of your starting bankroll. If you fund a session with $200 and the autoplay halts after $70 in losses, you've avoided the spiral where players keep manually spinning down to zero. The feature exists for a reason. Most regulated jurisdictions require operators to expose it. Use it.
Frequently asked questions
Does Shield of Athena have a Bonus Buy feature?
No. Play'n GO did not include a Bonus Buy in this slot. The bonus round can only be triggered organically by landing 3+ Cat Wilde scatters during normal play. Some affiliate sites incorrectly list a buy feature — they are confusing it with a casino's own promotional buy button, which is separate from the slot's math model.
What is the actual hit rate for the Medusa's Gaze Free Spins?
Community-tracked data on Slot Tracker (72,216 spins logged) shows the bonus hit rate at 1/72.5, or 1.38% per spin. That works out to roughly one bonus every 73 spins on average. The variance is wide — a 200-spin dry stretch happens to about 6.3% of sessions, and some sessions deliver two bonuses inside 100 spins.
Why does the demo say 'temporarily unavailable'?
Play'n GO controls public demo URLs region by region and through operator agreements. In some markets the demo is restricted entirely; in others it is paused while Play'n GO updates the math model. The slot is still playable in real-money mode at our partner casino, where it ships with the default 96.25% RTP version.
How much does the lower RTP version actually cost me?
Switching from the default 96.25% to the 91.25% variant costs roughly $50 per 1,000 spins at $1 stake. At $0.50 stake, it's $25 per 1,000 spins. Always check the in-game paytable info screen before depositing — the active RTP is printed there explicitly.
What is the maximum win in real money terms?
The slot caps at 10,000× the stake. At $0.10 minimum stake, that's $1,000. At $1 stake, $10,000. At $100 maximum stake, the cap is $1,000,000. The largest documented community win on Slot Tracker is $105,525, which sits well below the theoretical ceiling and confirms the cap is rarely hit.
Can I trigger the Medusa Re-Spin during free spins?
Yes — the Medusa Re-Spin stays active throughout the Medusa's Gaze Free Spins round. Every Shield that lands during a free spin can turn Wild and trigger locks plus respins inside the bonus. This is the core design that makes the free spins round explosive when it works.
Is Shield of Athena worth playing if I already enjoyed Book of Dead?
Yes, but expect rougher variance. Shield's 10/10 volatility produces longer dry stretches than Book of Dead, in exchange for a 10,000× ceiling (double Book's 5,000×). The Re-Spin mechanic also means more in-base-game action than Book's spin-and-wait-for-the-book rhythm. If you liked Book of Dead's pacing, Shield will feel slightly punishing at first.
