Quick verdict: Eye of Horus is Blueprint Gaming's Ancient Egyptian slot from 2017, and nearly a decade on it's still one of the studio's most-played and most-imitated titles — the "Family Tree" of Golden Tablet, Jackpot King and Megaways spin-offs it has since spawned is a good sign of how well the format landed. It runs on a simple 5-reel, 10-payline grid, but the Expanding Wilds and Upgrading Symbols feature give the free spins round a real sense of escalation. At up to 96.31% RTP and rated at the top of Blueprint's own volatility scale, it's built for players who like a classic, no-frills structure with genuinely high-variance swings.
The Story
Blueprint Gaming, the studio best known in the UK for arcade-style hits like Fishin' Frenzy, released Eye of Horus in November 2017 as a straightforward take on Ancient Egyptian mythology — no elaborate backstory, just "the all seeing eye" watching over the reels and promising big wins to those who catch its favour. There's no narrative arc to speak of; the theme exists to carry the symbol set and the Upgrading Symbols mechanic, and it does that job well enough that the game became one of Blueprint's flagship titles. Its popularity has since spawned an entire "family" of spin-offs — Eye of Horus The Golden Tablet, Eye of Horus Jackpot King, Eye of Horus Megaways and several more — all built on the same core mechanic, which is a reasonable proxy for how well the original format has held up.
Theme, Gameplay & Symbols
Eye of Horus plays out on a 5-reel, 3-row grid with 10 fixed paylines — a compact, classic structure compared to the cluster-pays and Megaways formats that have since become common. Low-paying symbols are the standard playing-card royals; higher-paying symbols draw on Egyptian iconography — scarabs, ankhs and canopic-style urns — building up to the Eye of Horus symbol itself, which doubles as the game's Wild.
The Wild's real job is expansion: any Eye of Horus symbol landing on reels 2, 3 or 4 expands to fill the whole reel as a stacked Wild, substituting for every paying symbol on that reel at once. It's a simple mechanic, but because it can land on the base game as well as during Free Games, it's responsible for a good share of the bigger base-game wins on its own, well before the bonus round comes into play.
Presentation & Sound
Visually, Eye of Horus goes for a straightforward temple-and-tablet aesthetic — sandstone reel framing, hieroglyph-carved borders, and a warm, gold-and-sand colour palette that leans into "treasure" rather than horror or mystery. It's not an especially elaborate production by modern standards; there's no cinematic intro or ambient animation between spins, and the symbol set is functional rather than lavishly detailed. What it does have going for it is clarity — every symbol reads instantly at a glance, which matters on a game with this much emphasis on watching for expanding Wilds. The soundtrack is a light, percussive Egyptian-themed loop that steps up in intensity once Free Games are triggered, with a distinct chime accompanying each Upgrading Symbols reveal.
How to Play Eye of Horus
- Set your stake using the bet selector. Blueprint Gaming's own published range runs from £0.10 to £100 per spin, though the exact limits available can vary by operator — and UKGC rules cap UK online slot stakes at £5 per spin (£2 for 18–24-year-olds), so UK players can't stake anywhere near the top of that range.
- Spin the 5x3 grid. Wins pay across the 10 fixed paylines when matching symbols land on adjacent reels starting from the leftmost reel.
- Watch reels 2, 3 and 4 for the Eye of Horus Wild symbol — landing there expands it into a full stacked Wild covering that entire reel.
- Land 3 or more Scatter symbols to trigger Free Games. The number you land determines how many you're awarded, up to a maximum of 12.
- During Free Games, watch for the Horus symbol specifically: 1, 2 or 3 landing in view award 1, 3 or 5 additional Free Games respectively.
- Each time an expanding Wild lands on reel 2, 3 or 4 during Free Games, the Upgrading Symbols feature activates — up to 5 of your high-paying symbols on the reels are upgraded to the next highest-paying symbol, stacking value onto the rest of the round.
Features & Mechanics
Free Games are triggered by landing 3 or more Scatter symbols anywhere on the grid, awarding an initial batch of Free Games — up to 12 depending on how many Scatters land. The round can be extended further by the Horus symbol specifically: Blueprint's own game data confirms 1, 2 or 3 Horus symbols landing in view award 1, 3 or 5 extra Free Games, giving a long Free Games run a genuine chance to snowball rather than being capped at a fixed number from the outset.
Upgrading Symbols is the feature that gives Free Games their escalating structure: every time an expanding Wild lands on reel 2, 3 or 4 during the round, up to 5 of the current high-paying symbols on the reels are converted to the next symbol up in the pay table. Play enough Free Games with a run of expanding Wilds and the reels can end up populated almost entirely with top-tier symbols, which is where the bulk of this game's win potential comes from — the base game's expanding Wild alone pays well, but it's the compounding effect across a long Free Games round that produces the standout results. Blueprint doesn't publish a specific hit-frequency figure for either the base game or the bonus trigger, so we won't put a number on how often Free Games land; treat it as an infrequent trigger consistent with the game's high volatility rating.
Volatility & Win Potential
Eye of Horus publishes five separate RTP configurations, from 90.25% up to a top figure of 96.31% — as with most Blueprint Gaming titles, which build is live depends on the operator, so it's worth checking the in-game info screen at whichever site you play rather than assuming the top figure applies. On its own five-point volatility scale, Blueprint rates Eye of Horus at the maximum — 5 out of 5 — putting it firmly in high volatility territory: expect longer gaps between meaningful wins, with the Upgrading Symbols feature doing the heavy lifting when a Free Games round does land. Independent slot trackers commonly cite a maximum win of 10,000x stake for the base game, though this figure doesn't appear on Blueprint's own game page, so treat it as a widely reported rather than officially confirmed ceiling. Bet range runs from £0.10 to £100 per spin as published by Blueprint, though as covered above, the UK stake cap keeps real-money play well below that ceiling — still giving the game a wide enough range for cautious and high-roller play alike within UK limits.
Pros & Cons
- Pro: The Upgrading Symbols mechanic gives Free Games a genuine sense of escalation rather than just repeating the base game at no cost.
- Pro: A simple, classic 5x3 grid and 10-payline structure that's easy to read at a glance, even mid-feature.
- Pro: A long track record — one of Blueprint's most enduring titles, with an entire family of spin-offs built on the same mechanic.
- Con: High volatility (5 out of 5 on Blueprint's own scale) means long dry spells between Free Games triggers are normal.
- Con: No official max win or hit-frequency figure published by Blueprint, so some commonly cited stats can't be verified against a first-party source.
- Con: Presentation is functional rather than elaborate — players wanting a more cinematic Egyptian theme may prefer a newer release.
Final Verdict
Eye of Horus earns its long shelf life the straightforward way: a simple, well-worn Egyptian theme paired with one genuinely effective mechanic in Upgrading Symbols, rather than a pile of overlapping features. It's not the most visually ambitious slot in Blueprint's catalogue, and the volatility means patience is required between meaningful wins, but the escalating Free Games round remains satisfying almost a decade after release — which is more than can be said for most 2017-era slots still in wide circulation. Worth trying via the free demo below if you want to see the Upgrading Symbols feature build before wagering anything for real.
