Slingo Centurion takes the same 5×5 grid format as Slingo Classic and builds a seven-level bonus ladder on top of it. Each level is a different feature borrowed from Inspired Gaming’s Centurion slot — Road to Rome, Caesar’s Free Spins, Wild Power Spins and more. Complete enough Slingos and a bonus triggers. The catch is the cost and how long it could take to get there, and in a session where one number sat unmoved on the grid, our Road to Rome Red eventually paid out.
Completing Slingos (five numbers in a row, column, or diagonal) moves you up a prize ladder that doubles as a bonus trigger system. Each rung unlocks a different feature. The paytable shows which bonus is attached to each line count, and the game keeps a running display of what’s reachable on the next spin. Extra spins are only offered when a bonus is still achievable; once the grid makes further progress impossible, the game ends.
The seven levels from lowest to highest are Reelus Maximus (5 lines), Prizes on Parade (6 lines), Caesar’s Free Spins (7 lines), Road to Rome (8 lines), Caesar’s Free Spins Red (9 lines), Road to Rome Red (10 lines), and Wild Power Spins (Full House). The Red versions of Caesar’s Free Spins and Road to Rome are boosted editions of their standard counterparts, with higher multipliers and additional rolls respectively.
Triggered at 5 Slingos. The game switches to a 5×3 slot layout where colossal symbols cover the first three reels entirely, playing out across all three in unison. Roman-themed symbols pay across 20 paylines: the Centurion logo, a chariot, the Colosseum, a helmet and shield, a silver coin, and card royals. Wins are multiplied by the initial stake.
Triggered at 6 Slingos. Three Roman soldiers march across the screen, each carrying a shield displaying a set of multiplier values. A moving light travels across each shield and stops to award the multiplier it lands on. The soldiers march in sequence, accumulating cash prizes across each shield before the total is paid out.
Triggered at 7 Slingos (standard) or 9 Slingos (Red). Two spinning drums determine the outcome. The left awards the number of free spins (5, 8, 10, or 12) and the right awards the multiplier applied to all wins (x1, x2, x3, x5, or x10). The Red version boosts both the spin count and multiplier ranges. Free spins play out on the 5×3 bonus reel with the standard Centurion symbol set.
Triggered at 8 Slingos (standard) or 10 Slingos (Red). A dice-rolling board game where the Centurion moves along a path of multiplier squares, accumulating prizes with each roll. Reaching Rome at the end of the board awards a substantial cash prize. The Red version boosts the prize values on every square and grants 2 additional free rolls.
Triggered on a Full House, with all 25 grid positions marked. The Centurion progressively places blocks of wilds on reels 2, 3, and 4 across three power spins, building toward a fully wild central section. This is the top bonus and therefore the hardest to reach.
The core symbol set works the same as other Slingo titles. Jokers appear on the centre reel and let you mark any number in the row above. Super Jokers mark any number anywhere on the grid. Devils are blocking symbols, centre reel only, and cannot be countered. Free Spin symbols add one extra turn. When 2 Jokers land on a single spin, the animated Centurion character emerges from the bushes and blows a trumpet to announce the double mark. All bonus game wins are multiplied by the initial stake, not the total including extra spins.
Slingo Centurion runs on 10 core spins rather than the 11 in Slingo Classic. Each spin draws 5 numbers on the reel beneath the grid; matches are marked off automatically, while Jokers and Super Jokers prompt a manual selection. Complete 5 or more Slingos within those 10 spins, and a bonus feature is locked in. Fall short of 5 after the core spins, and the game moves to the extra spin phase.
Extra spins are only offered if the bonus ladder still shows a route to a prize. The cost of each extra spin depends on the current grid position and the prizes still in reach, so a spin with a chance of unlocking Road to Rome will cost noticeably more than one aimed at Reelus Maximus. The Spin button shows the price before each purchase. Bets range from €0.20 to €25 and must be set before the game begins. The Play Controls menu also lets you set limits on extra spin count, maximum extra spin price, total game stake and total game loss, all worth adjusting before committing to a longer run.
The free play version works in the same way as the real-money game, including extra spin pricing and all bonus features. Bonus wins are always paid as a multiple of the initial stake rather than total spend, which is important to keep in mind once extra spin costs begin to build.
Slingo line prizes and bonus triggers are tied to the initial stake. Exact cash values for lower line counts vary by stake and are shown on the in-game paytable.

There are 12 win lines and 11 awards, as the final number always completes at least 2 lines simultaneously. The RTP of 95% applies to both core spins and each extra spin, based on best strategy for Joker and Super Joker placement.
The bonus features using a 5×3 slot reel (Reelus Maximus, Caesar’s Free Spins, Wild Power Spins) use the following symbol values. Wins are multiplied by the current line bet; only the highest win per line is paid across 20 paylines.
| Symbol | 5 of a kind | 4 of a kind | 3 of a kind | 2 of a kind |
|---|---|---|---|---|
| Centurion Logo | 500 | 200 | 50 | 4 |
| Chariot | 400 | 160 | 40 | n/a |
| Colosseum | 400 | 80 | 20 | n/a |
| Helmet / Shield | 300 | 40 | 8 | n/a |
| Silver Coin | 300 | 40 | 8 | n/a |
| J / Q | 200 | 20 | 4 | n/a |
| K | 200 | 20 | 4 | n/a |
The Wild symbol substitutes for all symbols. All values shown are multipliers of the line bet.
Seven bonus levels is the headline, and it's a genuine one. Centurion gives every line count a named destination, and the Road to Rome sequence at the Red level is a genuinely different experience to anything Slingo Classic offers. The cost of reaching it can be steep, and the audio loop is the game's most consistent irritant. Worth the step up from Classic for players who want more to aim for.
Slingo Centurion shows its best side once enough lines are in place. Its weaker side is clear in what it can cost to reach that point. The session that unlocked Road to Rome Red required €80.58 in total stake, including a stretch of extra spins priced at €11.85 each with one number still missing from the grid. The 300x win that followed returned €350, which made the decision pay off in this case. It would not always.
That is where the real trade-off sits. Extra-spin pricing increases near the top of the bonus ladder, with a single attempt to land the final number sometimes costing more than ten standard rounds. The game is transparent about that pressure, even stopping to ask whether you want to continue, which turns the decision to press on or collect into a genuine strategic call rather than an automatic one.
Four sessions across this review produced one game ending at 1 Slingo (no bonus reachable), two at 4 lines, and the extended run that reached Road to Rome Red. That range captures the format honestly. Most games will land somewhere in the middle of the bonus ladder or fall short of it, with the upper tiers requiring a commitment to extra spin purchasing that the paytable doesn’t always reward. Slingo Rainbow Riches and Slingo Cash Eruption cover similar bonus-ladder territory with themes that carry the between-spin experience more consistently. Centurion’s Roman setting does some of that work, but the audio loop undercuts it.
The audio is the session’s most persistent irritant. Heavy drums and clashing cymbals set the Roman tone, but the loop is short enough that the restart point becomes audible within a couple of games. There’s no way to keep game sound effects while muting the music; it’s on or off entirely, so the choice is between no audio at all and a background track you’ll no doubt want to silence within ten minutes. The tempo does lift in the later stages of a game, adding genuine momentum as you close in on a final line, but it’s not enough to offset the loop fatigue. The animated Centurion who lurches from the bushes to announce a double Joker is more jarring than charming, and, like several other animations, does not move smoothly enough to sit naturally within the otherwise polished Roman setting.
For players who find Slingo Classic too sparse, Centurion is the logical next step, more to aim for, more variation in what lands, and a Road to Rome sequence that, when it plays out at the Red level, justifies every spin that got it there.
Wild Power Spins on offer with a single number standing between the grid and a full house!
