Tower Quest slot review

Tower Quest slot: the short verdict

Tower Quest is a modest, old-school video slot. It has none of the giant multipliers or six-figure ceilings of newer releases; the most it can pay is 500× the stake. In return you get a medium-volatility game where the two bonus features are reasonably accessible and the swings are gentler than in most of the high-variance titles in our slot reviews.

The headline return is 96.24%, which is good for its age. The catch is the note that comes with it: Play’n GO supplies lower RTP versions too, and casinos choose which one to run. That single setting can matter more to your wallet than any feature, so this review spends some time on it.

How the features work in Tower Quest

The tower wild

The tower symbol is the game’s wild. It substitutes for regular symbols to complete wins across the 20 fixed lines. Because the paylines are fixed, every spin covers all 20 of them and your stake is spread across the whole set.

The Evil Wizard card bonus

Three or more Evil Wizard scatters trigger a card bonus. The idea is a duel: the wizard shows a card, and you try to reveal cards that beat it. Higher cards than the wizard’s earn prizes. It is a simple, quick feature that sits outside the reels altogether, and the help screen sets out exactly how the prizes are awarded.

Potion scatters and the free spins features

The second route runs on potions. Potion symbols act as scatters that are collected towards free spins features. Those features add two extras on top of ordinary spins: multipliers, which increase the value of wins, and sticky wilds, which stay in place across spins and so keep helping to form wins. How many potions each feature needs, and how the collection behaves between sessions, is something to confirm in the paytable.

Every feature payout is already counted inside the RTP. The potions you collect, the cards you reveal and the wilds that stick are all part of the 96.24% (or lower) the game returns on average, not extra value on top of it.

How to play Tower Quest online

1. Open Tower Quest at a UK-licensed casino and find the RTP in the game’s information screen.
2. Pick a stake. All 20 lines are always active, so you only choose the total amount per spin.
3. Spin. Each spin must last at least 2.5 seconds and there’s no autoplay on UK slots.
4. Land three or more Evil Wizard scatters to play the card bonus against the wizard.
5. Watch the potion collection build towards the free spins features with multipliers and sticky wilds.
6. Use the on-screen net spend and time display to keep track, and stop when you hit your limit.

Tower Quest RTP: why the version matters

At its top setting Tower Quest returns 96.24%, which means a house edge of 3.76%. The phrase “lower versions exist” means some casinos may run the same game with a smaller return. The reels, symbols and features look identical; only the long-run payback changes. Wizard of Odds’ slot guide (opens in a new tab) discusses how RTP settings vary by jurisdiction and operator. UK rules require the RTP to be available to players, as the Gambling Commission’s RTS 3 on game rules and the likelihood of winning (opens in a new tab) sets out, and our page on RTP display rules explains where to look.

The table below compares the top version with a hypothetical setting two percentage points lower, purely to show how much the version can cost. It is an illustration, not a published figure for any casino.

In other words, playing a lower version is like paying around half as much again for the same entertainment. Our explainer on why some slots have different RTPs at different casinos covers why operators pick different settings, and whether a higher RTP slot is better looks at what the difference means in a single session.

A £20 budget on Tower Quest at 10p, 50p and £1

Medium volatility sits in the middle of the scale our slot volatility guide describes: wins come along more regularly than in a high-variance game, but they are usually smaller. Combined with a 500× ceiling, that makes Tower Quest one of the gentler games to budget for.

At 10p the game’s two bonus routes have plenty of time to show up, and the expected cost of all 200 spins is only about 75p. At £1 the potential prizes are ten times larger, but 20 spins is a short session and the budget can disappear before a feature lands. Our answer on how long £20 lasts on a slot gives a fuller method.

The 500× max win in context

A 500× cap is small by modern standards. At 10p it is £50, at 50p £250, at £1 £500, at the £2 limit for 18 to 24-year-olds £1,000 and at the £5 limit for over-25s £2,500. For some players that is a plus: when the top prize is modest, more of the RTP has to be paid out through ordinary wins and features, which tends to make sessions less erratic. If you’re looking for a big ceiling, a game such as Book of Dead at 5,000× is a different proposition.

UK slot rules and Tower Quest

Tower Quest predates the current rules, but UK-licensed casinos must run it under them. That means a maximum stake of £5 a spin for players aged 25 and over and £2 for 18 to 24-year-olds, as the Commission’s online slots stake limit guidance (opens in a new tab) sets out (see our slot stake limits page), no autoplay, at least 2.5 seconds per spin, no turbo or slam-stop and no celebrating a return no bigger than the stake, under the game design rules in force since 31 October 2021. Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players.

Tower Quest myths and facts

• Myth: a long potion drought means free spins are close. Fact: each spin is random and independent, as our page on independent events explains. Read the paytable to see how the collection itself works.
• Myth: late-night play pays better. Fact: the RNG doesn’t know the time. See do slots pay out more at certain times.
• Myth: you can read the wizard’s cards. Fact: the cards come from the game’s random number generator and the feature is already priced into the RTP; the help screen explains how the duel plays.

Play’n GO has plenty of fantasy and adventure titles. Rise of Merlin keeps the wizard theme, while Legacy of Egypt and Book of Dead offer higher variance. See the full list on our Play’n GO page.
