40 Thieves Game Overview

40 Thieves places card suits, curved swords, smoking pipes, horses and a masked thief on five reels and four rows. Winning combinations normally run from the leftmost reel across the game’s 40 fixed lines. Stacked regular symbols and stacked Wilds can occupy several positions at once.

40 Thieves is listed by Wildz with a default RTP of 96.09%, low volatility and demo access. Published sources disagree about the maximum-win multiple, so no unverified ceiling is stated on this page. The information panel inside the current game build remains the relevant source for its paytable and available betting limits.

How Does 40 Thieves Work?

40 Thieves evaluates matching symbols on 40 fixed paylines after each paid spin. Standard combinations form from left to right beginning on the first reel, and most symbols require at least three matching icons. The masked thief is an exception because a two-symbol combination can already carry a value in the paytable.

40 Thieves uses stacked symbols to place the same icon across consecutive spaces on a reel. This can connect one symbol across several active lines in the same result, but it does not make a win certain. Every reel stop is generated independently by the game’s random system.

40 Thieves Stacked Symbols

40 Thieves can display both ordinary paying symbols and Wild symbols in stacks. A full or partial stack covers several positions on one reel, creating multiple line intersections when matching symbols appear on neighbouring reels. The mechanic operates in the base game as part of the standard reel design.

40 Thieves does not let the player select which symbol will stack or where a stack will stop. Raising or lowering the wager changes the amount at risk rather than controlling the symbol arrangement. Stacked icons can contribute to several line wins, but they can also land without completing any payable combination.

40 Thieves Wild Symbols

40 Thieves uses a dedicated Wild symbol that substitutes for ordinary paying icons when this completes a line. The Wild does not replace the amulet Scatter because the Scatter has a separate feature-triggering function. Wild stacks can cover more than one reel position in the same spin.

40 Thieves adds the masked thief as another Wild only during Free Spins. This temporary conversion increases the number of symbol types able to substitute in that round. It remains a programmed feature condition and cannot be activated by a betting pattern or a manual choice.

40 Thieves Gamble Features

40 Thieves offers two optional risk features after qualifying wins: a card-colour game and a ladder game. The card option asks the player to predict red or black, while the ladder option risks the current amount for a higher listed step. An unsuccessful choice can reduce or remove the amount placed at risk.

40 Thieves gamble features do not change the random result of the spin that produced the original win. Choosing to use them increases exposure after a payout has already been calculated. Players can collect an eligible win instead of placing it into a gamble round.

40 Thieves Free Spins

40 Thieves awards 10 Free Spins for three amulet Scatters, 15 Free Spins for four and 50 Free Spins for five. The Scatters can land anywhere in view rather than needing to follow one of the 40 paylines. Additional amulets during the feature can retrigger the round.

40 Thieves turns the masked thief into an additional Wild for the duration of Free Spins. The normal Wild remains active, so the bonus can contain two different substituting symbols. Neither the largest starting award nor a retrigger can be guaranteed by stake size, spin timing or previous outcomes.

40 Thieves RTP

40 Thieves has a Wildz-listed Return to Player figure of 96.09% for the MGA build used by this page. RTP is a long-term theoretical percentage calculated across a very large number of rounds. It does not state how much one player will receive in a particular session.

40 Thieves may exist in other regulated configurations with different mathematical settings. Players should therefore check the information panel shown inside the version they open before staking real money. The figure displayed in that panel takes priority for the active game session.

40 Thieves Volatility

40 Thieves has a volatility rating of 4 out of 10 in the Wildz catalogue, which places it in the low-volatility band used on this platform. Lower volatility generally describes a result pattern weighted more towards smaller, more regular returns than a high-volatility model. It does not mean that every session will contain frequent wins.

40 Thieves can still produce losing sequences because volatility is not a promise about short-term outcomes. Free Spins, stacked symbols and gamble choices can make individual rounds differ considerably. Previous spins do not make a particular symbol or feature due to appear next.

40 Thieves Maximum Win

40 Thieves does not have a verified maximum-win multiple that can be stated consistently from the available sources. Published figures conflict, and repeating one of them would present an uncertain number as fact. The game’s current paytable should be checked for the upper limit applying to the active configuration.

40 Thieves also has no progressive jackpot according to the Wildz game record. Any maximum shown in the information screen is therefore a fixed limit of that game build rather than a network prize that grows with play. A listed ceiling remains a mathematical maximum, not an expected result.

How to Play 40 Thieves in the United Kingdom

40 Thieves starts by opening the information screen, reviewing the 40 paylines and selecting an available stake. A paid spin then stops the five reels, calculates line wins and applies any Scatter or Wild functions. Eligible wins may also present the optional card or ladder gamble controls.

40 Thieves is an online slot, so Great Britain-licensed operators must apply the statutory per-game-cycle limits. Adults aged 18 to 24 may stake no more than £2 per game cycle, while customers aged 25 and over have a £5 maximum. These limits have applied since 21 May 2025 and 9 April 2025 respectively.

Can You Play 40 Thieves on Mobile?

Yes, 40 Thieves can be played on compatible smartphones and tablets as well as desktop devices. The mobile version retains the 5x4 layout, 40 paylines, Free Spins and gamble features. Controls may be rearranged to fit a smaller screen without changing the core game rules.

40 Thieves normally opens through a supported mobile browser within the casino site. Device software, connection quality and account requirements can affect access. Mobile play does not alter the random probabilities or make a feature more likely to trigger.

Can You Play 40 Thieves for Free?

Yes, 40 Thieves has a demo mode at Wildz that uses virtual credits. The free version lets players inspect the paylines, stacked symbols, Free Spins rules and gamble controls without staking deposited funds. Demo winnings have no cash value and cannot be withdrawn.

40 Thieves free play at a Great Britain-licensed gambling operator remains subject to age-verification rules. Licensed remote operators must verify age before giving a customer access to a free-to-play version of a real-money gambling game. Demo results also do not predict what will happen after switching to real-money play.

40 Thieves in the United Kingdom

40 Thieves may be supplied by online casinos holding the appropriate Gambling Commission permission and carrying the Bally Wulff title. British customers must be at least 18, complete the required verification checks and remain within the online-slot stake limits. The operator’s own game page should identify the mathematical version currently offered.

40 Thieves is listed by Wildz internationally, but Wildz states that visitors from the United Kingdom are redirected to partner casinos. UK players should use the Gambling Commission public register to confirm that the operator they reach is licensed for Great Britain. The international Wildz listing should not be treated as proof that Wildz itself accepts UK registrations.

United Kingdom Rules for 40 Thieves

40 Thieves real-money play in Great Britain falls under the framework supervised by the Gambling Commission. Operators serving England, Scotland and Wales must hold suitable remote gambling permissions and verify a customer’s name, address and date of birth before gambling. The minimum age for online casino play is 18.

40 Thieves players should distinguish Great Britain from Northern Ireland when reading these rules. Gambling Commission licensing under the Gambling Act 2005 covers England, Scotland and Wales, while Northern Ireland has a separate legal framework. Current operator terms and the public register should be checked before depositing.
