A fresh window on client 1.21.4 hands out €5,000.00 to play with and sets the stake to €2.00, adjustable from €0.10 to €2,000.00. Nothing below was played at any other stake.

One tile, one number, ten symbols at most

The Stackways tile in this game is a single symbol with its value printed on it. When it lands, the game picks the paying symbol that would make the longest win from what is already on the reels and fills the tile's reel with as many copies as the number says, between 2 and 10. A reel that ends up holding six symbols counts six times in every way that runs through it. If no win would come of it, the tile does nothing, and when two symbols could make equally long wins a random draw decides.

Mayan Stackways six serpent heads stacked
Reel 2 holds six serpent heads; counters 1 x 6 x 1 x 1 x 1 read 6 STACKWAYS, WIN €30.20 at €2.00.

Five serpent heads at 2.5x would pay once on a bare board. In the frame above, from our media session, six of them are squeezed into reel 2, and they paid on six ways at once. A full line of any card rank from 10 to A pays 0.7x, the five pictures 2x to 4x, with the green-headdress portrait at the top.

Over the 500 logged spins a tile appeared on 91 of them, never with a number above 7. Of the €475.20 the base game paid, €330.60 came on the 45 spins where a stack was part of a winning way. The top one, spin 65, put the gold-headdress woman on 12 ways for 36x.

Where do the coins of Mayan Gold end up, and when are they paid?

Each Coin that lands adds its value to a counter above its reel, and a Multiplier symbol multiplies that counter by 2 to 5. When a Stackways tile hits a reel, the reel fills with Coins all worth the counter and locks. A Collect scatter moves every Coin on locked reels into the Vault under the grid and unlocks those reels. Coins pay nothing before the end, and the round ends only when all five reels are locked at the same moment. Then the stacked Coins plus the Vault, times the bet, are the prize.

Counters, a Vault and five locked reels

Mayan Gold needs four Skulls in one base spin, or €400.00 from the menu. It plays on reels of its own, where Coins, Multipliers, Stackways tiles and the Collect scatter do all the work.

Mayan Stackways Mayan Gold coin values
GAME INFO: bronze Coins 1 to 5, silver 10 to 20, gold 25 to 1000, and the X Multiplier with values 2 to 5.

Timing decides the size of the prize. A tile that lands while its counter is small locks in a cheap stack, and the next Collect banks it and frees the reel to try again. A tile that lands after a gold Coin and a x5 Multiplier locks a reel worth far more. Since the round only stops with all five reels locked together, a Collect can stretch it, and every banked stack stays in the Vault until the end.

Five Skulls start A Golden Opportunity, the same round with 50 already on every counter. The studio promises at least 500x from it, and our own arithmetic from the rules agrees: five locked reels of at least two Coins each, at 50 a Coin. GAME INFO adds that this start cannot come from buying Mayan Gold. We saw neither version in the log, and this section is built from the rules.

Three Skulls, and a red S that keeps a reel live

Stack Spins opens on three Skulls and lasts 10 free spins. Some slot listings say two Skulls are enough. GAME INFO says three, and all three natural rounds in our log began on exactly three. Tiles land more often here, and a red Reel Activator marked S claims its reel, and a Stackways tile lands there on every free spin that follows. Three more Skulls add 4 spins.

Three Skull scatters with FS on their helmets, on reels 1, 3 and 4, start the round; WIN €0.20.

A Stack Spins we paid €220.00 for at a €2.00 stake built many short towers and no tall ones. Its best spin dropped a 5 tile on reel 1 and a 3 tile on reel 3 next to a single portrait on reel 2. That made 15 ways of the green-headdress portrait across three reels and €45.00.

The round paid €61.00 in all, 30.5x the stake against a price of 110x. The clip runs from the trigger to the Total Win screen.

Stack Spins bought for €220.00: a 5 and a 3 tile stack the headdress portrait for 15 ways and €45.00, and Total Win reads €61.00 after 10 free spins.

Down to the low point on spin 477, then 921.2x

A script ran the 500 paid spins behind this section, €2.00 each, on Hacksaw's demo server, and stored every answer. They brought three Stack Spins and no Mayan Gold. Two Skulls landed together on 21 spins, four never.

The first two rounds were small. Spin 63 returned 12.2x and spin 221 12.4x, neither with a Reel Activator, and the balance slid for most of the session. It reached €4,549.40 on spin 477.

Two spins later Stack Spins opened again, and this time an Activator landed on reel 1 in the first free spin and another on reel 4 in the seventh. In between, J stacked on reels 1, 2, 3 and 5, with two plain J on reel 4, for 800 ways, worth €1,120.00 on its own. On the ninth free spin J did it again over 420 ways for €588.00. That round alone paid €1,842.40, 921.2x the bet.

The log finished on €6,366.40, 236.6% of the stakes, from a run in which 32% of spins paid and a typical win, by the median, was 0.45x. Take spin 479 away and it would have closed well short of the starting credit.

Medium on the coin card, Very high on the stacks

Hacksaw rates each card in this menu separately. BonusHunt FeatureSpins and Stack Spins say High, Stackways FeatureSpins Very high, and the dearest card, Mayan Gold, only Medium.

The two ACTIVATE cards stay switched on, and keep charging, until you disable them. Stackways FeatureSpins, at 40x a spin, guarantee at least two tiles, though a tile with no win to make stays inert. Stack Spins and Mayan Gold are one-off purchases.

The menu at €2.00: two ACTIVATE cards at €6.00 and €80.00, two BUY cards at €220.00 and €400.00.

Credits in this window are played at 96.23%, and the four cards are rated between 96.27% and 96.33%. Casino sites list 94.29%, 92.41% and 88.38% too, so a real-money copy can be set lower, and where a market bars feature buys, a casino hides all four cards.

What Benny the Beer did with the idea

Five months later Hacksaw put Stackways into Benny the Beer, released in October 2023. The board is the same, as are the 100,000-way ceiling, the absent Wild and the top pays of the five pictures. Benny drops the 10 from the card ranks, splits the tile into a numbered kind and a question-mark kind, and swaps both bonuses for two books in which chosen symbols stack.

Benny's volatility rating is 3 of 5 where this game has 4, and its demo runs at 96.17% instead of 96.23%. Its menu holds 5 cards, the dearest at 300x, while this one stops at 4 and 200x. Our Benny session ended at 140%, its best round worth 193.2x.

How many Skulls start Stack Spins?

Three in one base spin, per GAME INFO, although some listings say two. Four open Mayan Gold and five A Golden Opportunity.

Does a bought Mayan Gold ever start with 50 on every counter?

No. The card gives the ordinary version, and only five Skulls in the base game open A Golden Opportunity.

How long does a Reel Activator last?

Until Stack Spins ends. The reel it lands on gets a Stackways tile on every remaining free spin, and our 921.2x round had two of them.

Can Mayan Gold end with a reel still unlocked?

No. It ends only when stacked Coins lock all five reels together, and a Collect unlocks reels and keeps it going.

Most base spins in Mayan Stackways are quiet, and a stacked reel is the event. Our session had two small bonuses and a long slide before one Stack Spins with two Activators outpaid the other 499 spins combined. The coin round, Mayan Gold, never came in 500 spins, so buying it with play credits is the way to watch the counters work.
