Mayan Stackways slot

What the Mayan Stackways slot is

Mayan Stackways comes from Hacksaw Gaming, the Malta-based studio behind Wanted Dead or a Wild, and it arrived in 2023. The theme is a jungle temple, but the reason people search for it is the mechanic in its name. Rather than adding rows across the whole grid, as a Megaways game does, it stretches individual reels by dropping a tall stack of one symbol into them.

That makes it an unusual hybrid. Most of the time it plays like a standard 1024 ways slot, with three or more matching symbols on adjacent reels from the left paying in any row. When a StackWays symbol appears, the reel it sits on suddenly holds many more positions, and the ways count jumps with it.

How StackWays works, with the ways maths

Ways games count wins by multiplying the number of symbol positions on each reel. Four positions on each of five reels gives 4 × 4 × 4 × 4 × 4 = 1,024 routes from reel 1 to reel 5. Change any one of those numbers and the total changes in proportion. Our explainer on ways-to-win slot machines sets out the method.

StackWays changes those numbers mid-spin. When the special symbol lands, it becomes a stack of between 2 and 10 matching symbols on that reel. The reel is treated as taller than four positions, so it contributes more ways. It works rather like a stacked symbol, except the stack adds height instead of simply filling existing rows.

A simplified worked example

The game’s exact counting rules are in its help screen; the arithmetic below simply shows why stacking matters. Imagine reel 2 normally shows 4 positions. If a stack lifts it to 8 positions, the grid becomes 4 × 8 × 4 × 4 × 4 = 2,048 ways, double the base. If a second reel is lifted to 8 as well, the count becomes 4 × 8 × 8 × 4 × 4 = 4,096. Stack several reels and the total climbs very quickly.

The win from a stacked reel also grows because the stack is one symbol. If reel 3 holds a stack of 10 matching symbols and reels 1 and 2 each show that symbol once, a three-of-a-kind is paid on 1 × 1 × 10 = 10 ways at once. That is the key to the game: the payout comes less from rare symbols and more from many ways paying the same combination together.

Playing a spin on the Mayan Stackways slot machine

1. Set the total bet. UK casinos cap it at £2 a spin for players aged 18–24 and £5 for those aged 25 and over.
2. Press spin. The random number generator settles every reel stop and any StackWays outcome straight away.
3. Watch the reels for at least 2.5 seconds; UK slots can’t run faster.
4. If a StackWays symbol has landed, the stack expands and the ways are recounted.
5. All left-to-right ways wins are paid, and scatter counts are checked for the bonus rounds.
6. Your balance and net position update on screen.

Nothing you do between pressing spin and the result appearing has any effect. Online, stopping the reels early changes nothing, and UK versions don’t offer a slam-stop button anyway. See can you stop a slot spin early for why.

Mayan Stackways free spins and bonus rounds

Published game descriptions list two scatter-triggered bonuses. The free spins round, described as Stack Spins, makes StackWays symbols appear more often and can switch on reels so that they keep landing stacks for the rest of the round. A larger scatter count leads instead to a coin-collecting bonus, described as Mayan Gold, in which reels build up coin values that are banked and paid at the end.

Scatter counts, the number of free spins, retrigger rules and coin values are all set out in the help screen of the version you open. Because those details can differ in how they are presented between casinos, read them there rather than relying on any summary, including this one. The general mechanics of a scatter trigger are covered on our page about what triggers a bonus round.

No bonus trigger rate is confirmed in our checked data. Any figure you see quoted elsewhere describes a long-run average, not a schedule, and a bonus can take far longer than average to appear.

Mayan Stackways RTP and why the version matters

The best published Mayan Stackways RTP is 96.23%. Hacksaw, like many studios, supplies lower settings too, and a casino chooses which one to run. Each setting has been tested, so a lower one isn’t rigged, but it costs more over the long run. Our page on slot RTP variants explains how studios supply them.

Compare that with a hypothetical lower setting of 94%: at £1 a spin, 100 spins would cost about £6 on average rather than £3.77. Over 1,000 spins at £1, the gap grows to roughly £22. That is why checking the RTP line matters more for a regular player than for someone trying the game once. Our guide on where to find RTP on UK slots shows where casinos list it.

Bear in mind that every one of these numbers is an average over an enormous number of spins. A single session of 100 spins can end with most of the stake gone or with a profit, depending on whether a StackWays stack or bonus lands.

Mayan Stackways max win and volatility: what to check

Our checked data doesn’t include a confirmed Mayan Stackways max win or volatility rating, so this page doesn’t state either. Both appear in the game’s rules: the max win is usually written as a multiple of the stake, and Hacksaw shows a volatility rating in its game information.

Once you have the multiple, converting it to pounds is simple. Multiply the cap by your stake: a cap of X times the stake is worth X × £2 at the 18–24 limit and X × £5 at the 25+ limit. Our page on max win caps explains what happens when a feature reaches it.

The 1,000× figure in that table is a round number for illustration only, not the game’s cap. For a feel of what different volatility levels mean for a budget, see our volatility explainer.

What the UK version of Mayan Stackways leaves out

Outside Great Britain, Hacksaw games commonly offer paid ways into features. Slots supplied to UK-licensed casinos don’t include a bonus buy, so in the UK the bonuses are reached only through normal spins. Our page on bonus buy in the UK covers this.

The game design rules the Gambling Commission brought in on 31 October 2021 also apply: no autoplay, no turbo or slam-stop, at least 2.5 seconds per spin, no celebration of a return equal to or below the stake, and a constant display of your balance and net position. The wording is in the Commission’s summary of changes to the technical standards (opens in a new tab), and our UK slot game design rules page explains each one.

Stake caps come from the casino side. Players aged 25 and over can stake up to £5 a spin (since 9 April 2025), and 18–24s up to £2 (since 21 May 2025), as set out in the Gambling Commission’s stake limit guidance (opens in a new tab). The £2 limit for 18 to 24s has its own page.

Mayan Stackways demo and help screen checks

A Mayan Stackways demo, where a UK casino provides one, is free demo play after age verification. Since May 2019, operators have had to check you are 18 or over before any free-to-play slot opens. The demo runs the same maths as the real-money game, which makes it a useful place to read the rules in full.

1. Find the RTP line and note the percentage; 96.23% is the best published setting.
2. Read the StackWays section for how stacks form and how ways are counted.
3. Note the scatter counts for each bonus and the number of free spins.
4. Find the maximum win statement and convert it at your stake.
5. Look for the volatility rating in the game information.

Our demo slots guide explains how UK demo play works, and are free slot games the same as real ones answers the common worry about demo maths.

Stacking myths and facts

• Myth: a run of spins without a stack means one is coming. Fact: every spin is independent, so a dry run changes nothing.
• Myth: more ways means a higher RTP. Fact: the ways count changes how wins are spread, not the long-run return, which stays at the stated percentage.
• Myth: a lower RTP version is rigged. Fact: it is a tested, legitimate setting that simply costs more over time.
• Myth: playing at a quiet time of day helps. Fact: online results don’t depend on the clock or on other players.

Our guide to slot machine myths covers the wider list, including near misses and ‘due’ machines.

Mayan Stackways compared with similar Hacksaw slots

The closest comparison in Hacksaw’s own range is Stick ’Em, which uses the same 5 × 4 grid and 1,024 ways. Players who like the stacking idea but want to compare it with other expanding-grid systems can look at Megaways slot machines, where every reel changes height on every spin, or Nolimit City’s xWays, which expands individual symbols.

More of the studio’s games, including Wanted Dead or a Wild, are listed on our online slots hub.

Who the Mayan Stackways slot suits

It suits adults who enjoy watching the ways count rise and who are happy to set a firm budget. A £20 budget at 20p a spin is 100 spins, with an average cost at 96.23% of about 75p, but actual results will vary widely. Our bankroll guide shows how to size stakes for a session.
