Wild Cauldron Demo: The Grid That Grows While It Pays

Winning symbols sink to the floor of the cauldron

A winning combination locks and slides to the bottom of the reels while everything else is cleared and refilled from above: the Locking Symbol Tumble, which repeats until a tumble brings no new win. In the server log nothing is paid along the way; each of our 125 winning spins was paid in one sum when its run ended.

A pink horned monster heads the paytable at €3.50 for six on a way at €1.00; the six rune tiles pay €0.10 for three and at most €0.50 for six.

The first tumble after a win always brings a fifth row, and for 69 of our 125 runs that was all: nothing new matched on 15,625 ways, and the run was paid.

Rows to the power of six, from 4,096 ways up to 262,144

A way takes one square from each reel, so 6 reels of 4 rows give 4 multiplied by itself 6 times, 4,096. Each winning tumble adds a row, and the counter jumps to 15,625, 46,656, 117,649 and 262,144, the 8-row maximum on the rules screen. Quickspin's page writes it rows first: 4×6 to 8×6.

A full board holds 48 symbols, and reaching it does not end a run: 8 of ours kept tumbling there, spin 398 for 6 tumbles in all.

Each Wild adds 1x to everything already locked

The Wild is a red coin stamped with a gold W, and the rules say it "increases win multiplier by x1". Quickspin's page caps the multiplier at 7 for a single spin and resets it with the reels.

As a run is paid only once, the multiplier it ends on covers the whole sum. Spin 398, our best base result, had one Wild on its first screen and a second on the tumble that filled the eighth row; all 42.3x was paid at x3, wins locked at x2 included.

Without a Wild, 62 of our base runs ended at x1; 54 ended at x2 and 9 at x3, and runs with a Wild paid €322.30 of €364.90.

In the free spins the rows stay until the round ends

The game page and sheet name only the top count, 6 Bonus Scatters for 12 free spins; the rules screen fills in 4 for 8 and 5 for 10. The potions must arrive within one tumble run, and on spin 372 they did: none on the first two screens, 3 after the second tumble and a fourth on the last.

In the bonus, says the page, rows and multiplier carry over. Spin 372's free spins began on 4,096 ways at x1; the second added a row and a Wild, the third paid nothing but its Wild lifted the multiplier to x3, and the board was full by spin 7 of 8. The last spin, at x5, paid €54.00 of the round's €100.30.

The bonus on spin 484, also 8 spins from 4 potions, had five blank spins before €1.60, €1.20 and €4.80, reaching 8 rows at x3 only on its last spin.

Most of our runs stopped at five rows, and the money sat at eight

Session in brief: 500 spins, €1.00 each, on 25 Oct 2026, 94.6% back, wins on 25% of spins, each one a tumble run, and no dry spell past 15 spins.

The 16 runs that reached 8 rows, about one win in 8, paid €176.40, 48% of the base game's return; the 69 one-tumble runs averaged €0.97.

Quickspin's sheet books 10.19% of the RTP to "Base Game", 60.06% to "Base Feature" and 25.84% to free spins, without defining the feature. In the rules the base game's only feature is the tumble run with its rows and multiplier, so we read it as: a spin without its tumbles returns about a tenth of the stake, the rows after a win about six tenths. Our log fits that only roughly, since a one-tumble run is not a spin without tumbles: one-tumble runs returned 13.4% of the stake, longer runs 59.6%, free spins 21.6%.

The balance hit its low, €4,829.50, after spin 371; the next spin triggered the first bonus, 117.7x with its run (€17.40) and free spins (€100.30). The second added 8.2x.

Worth playing if you can wait for row eight

Two top wins are on record. The game sheet records 21,199.5x from a simulation of 100 billion spins, while the demo server, at the same 96.09% RTP, reports 2,757.4x from 50 billion. Nothing Quickspin publishes explains the gap; our spec plate shows both.

The nearest relative here is Cash Truck 2, also rated 5, whose board likewise grows as it wins (6 reels, up to 7 rows); its sheet's 100x odds are 1 in 821, next to 1 in 885 here.

Most runs are short; the value lies in the few that reach the eighth row carrying a Wild or two, and in free spins that keep both, so it suits players who enjoy watching a board fill and accept a 5-of-5 rating. Only one RTP model appears on Quickspin's sheet, 96.09%, and the demo server reports the same figure.
