A row of shrink-wrapped hearts stacks up on a reel in the Corpse Cart slot, an undead shop assistant slaps a promo sticker over them, and the 3 squash into a single symbol. Win with it, and a multiplier locks to that cell and holds for the whole round, boosting every win it joins while the reels keep cascading.
AvatarUX calls the system Infinity Stacks as there is no limit to how many symbols a stack can hold. It plays out in a rotting corner store, its strip light flickering, a shopkeeper chattering his jaw beside the reels, and a stray eyeball rolls along the foot of the screen now and then, pausing in the middle before it carries on.
Infinity Stacks is the feature Corpse Cart is built around. When 3 or more matching symbols land vertically on a reel, they squash into a single stacked symbol with a squelch, with the count printed beside it. Wilds can join in too, and need only 2 symbols to start a stack.
Once formed, a stack counts every symbol inside it toward a win, and there is no cap on how deep it can go, so a reel can end up several symbols high.
The stacks are only half of it. The first time a stack helps secure a win, its multiplier is fixed to that cell and stays put while the round plays out, straight through the tumbles that follow. Every later win over that cell carries it forward, so what locks in early keeps adding up long after the symbols that earned it have gone. Get a few sitting across the reels at once, and the totals climb quickly.
Every win clears itself away. Winning symbols pop in a splash of red, fresh ones tumble down to fill the gaps, and the reels keep cascading for as long as fresh wins arrive. This is where those locked multipliers matter most, since each tumble is another shot at a win running back over a cell that already carries one.
The Bonus symbol is a full undead takeaway, burger and brain and fries in one. Land 3 for 7 free spins, 4 for 10, or 5 for 12.
The grid adds an extra row for the round, stretching out to 5×5, and every extra Bonus that lands during the feature adds 1 more spin.
The two features below appear only in the free spins, and they are what make the bonus worth the trip.
The first of those, Synced Reels, links 2 to 4 reels for a single spin so they move as one. Matching sections stretch across the group at once, turning an ordinary spin into a serious stacking chance. The number of synced reels changes every go, and the pattern never repeats, so each spin brings its own shot at a monster stack.
The other feature that will only show up in free spins is a row of mice above the reels, one per reel, called Symbol Selectors.
When the reels stop, each mouse shows a symbol with a gormless little grin, and if that symbol also landed below it, the mouse gulps it down and slides down the reels, leaving a trail of green as the remaining symbols change to match. Match the right mouse to its reel, and a thin win can fatten into a solid column.
Corpse Cart pays every way, over a floor of 1024 ways. Three or more of a symbol pay on a run of touching reels that has to begin at the left edge, however they land, with no payline required. The twist is what a stacked reel does to the sum. Hold more than one of the same symbol on a reel and the game multiplies the ways out, so 2 on reel 1, 3 on reel 2 and 2 on reel 3 reads as 2x3x2, or 12 ways for that symbol. It is why a plain-looking spin can pay far beyond what it looks.
Reaching the free spins need not wait on luck. The buy menu sells 3 ways in, each priced off your stake. The cheapest is 75x, the middle 150x, and the premium 300x, each dropping you into its round. If a lump sum feels steep, the ante bet is gentler, adding 50% per spin for double the odds of a natural trigger, and stays active until you switch it off.
Stakes cover a lot of ground too. The demo runs from a €0.10 spin to €1,000 a go, so the reels suit a careful sitting or a heavy one, with every mode, buys and ante alike, open in free play.
In standard play the game returns 96.07%, and the buys give back more, not less, from 96.39% up to 96.73% on the dearest one, with the ante at 96.25%. Some casinos run lower-paying versions, so the paytable repays a look before you play, the figure sliding to 94.05% or 90.53% by region. Volatility is rated very high, and the round stops dead at a 10,000x win, ending on the spot and banking that amount.
The paytable pairs its symbols off, so the two organs at the top pay alike, the lungs sit level with the severed hand, and the 6 cards flatten to 2 rates.
| Symbol | 5 | 4 | 3 |
|---|---|---|---|
| Heart | 2.5x | 1x | 0.5x |
| Brain | 2.5x | 1x | 0.5x |
| Lungs | 2x | 0.8x | 0.4x |
| Hand | 2x | 0.8x | 0.4x |
| Braingool drink | 1x | 0.5x | 0.3x |
| Finger fries | 1x | 0.5x | 0.3x |
| Liveros crisps | 1x | 0.5x | 0.3x |
| A / K / Q | 0.5x | 0.4x | 0.2x |
| J / 10 / 9 | 0.3x | 0.2x | 0.1x |
All figures are multiples of the total bet, taken at the €1 spin we played. The Wild has no value of its own, and the Bonus is a scatter, so neither appears in it.
Corpse Cart might look like a slot running on little more than zombie theming, and it would be easy to leave it there. Do that, though, and you miss what it is really built for. Underneath is a fun and rewarding piece of machinery: a multiplier that locks to its cell, keeps counting while the reels tumble, and gets more room to work when the free spins widen the grid to 5x5. The zombies are the shopfront. The engine is behind the meat counter.
The setting is a rotting little supermarket, a strip light guttering over shelves of shrink-wrapped body parts, and the studio has clearly had fun with it. A zombie shopkeeper slumps at the side of the reels. His jaw chatters, his head wobbles, his eyes fall shut now and then, and a blood-soaked paper bag dangles from one hand. The theme runs right through to the symbol art, with slushies branded Braingool and a bag of crisps called Liveros grinning out from the low pays, with each win totting up in red and yellow.
Smaller touches reward a second look. A finger crawls the foot of the reels, the odd drip runs off the screen, and every so often a loose eye rolls out across the bottom, halts in the middle as if it has spotted something, then trundles on. None of it is played for scares. This is horror with a wink, nearer a Saturday-morning cartoon than anything out to unsettle you, and it sets the tone before a win even lands.
Strip the theme away, and the locked multiplier is what the game is built on. A stack has to pay once before its multiplier shows, but once it does, that value is pinned to the cell for good. As the reels fall and refill around it, any win crossing the cell is boosted again, and with several cells live at once, one spin can pay in bursts, each bigger than the last. It is the one properly fresh idea in the game, turning the gap between a flat round and a huge one into a matter of how many multipliers you get to stick.
The honest catch is that standard play rations those moments. Left to ordinary spins, stacks form often but rarely run deep, and the few multipliers that do lock tend to expire with the round before amounting to much. The best our base spins managed was a €7 return off 10 ways. The feature really needs the free spins to breathe. Across the wider 5×5, the synced reels throw far more matching symbols together, whilst the mouse selectors can often turn a near miss into a full run.
We put the 300x premium buy to the test, and it ran hot. The 12 spins opened quietly, then multiplier after multiplier piled on, and the win banners the game hands out started to climb. One spin hit an EPIC DEAL of €1,228.50, a later one €3,953.50 on its own, and the round shut on the top MEGA MEAL tier at a €5,228.20 total from a single €1 stake, one of the bigger bonus results in our review to date. It all went by in a blur though, since even at its calmest the round moves too fast to follow which stacks built that total.
