A normal spin has one outcome. A cascading spin has a sequence. The reels land, wins are paid, the winning symbols disappear, everything above drops down, fresh symbols fill the top, and the new arrangement is checked as if it were a new spin at no extra cost. The sequence continues until an arrangement produces no win. Every step in the sequence is a cascade, and a spin's total is the sum of all of them.
The mechanic suits three grid formats. Ways games such as Bonanza use it on six reels of changing height. Cluster games such as Reactoonz use it on a square grid. Scatter-pays games such as Sweet Bonanza and Gates of Olympus use it on a six-by-five grid where eight matching symbols anywhere pay. In all three, the removal-and-refill is the same, and what differs is the multiplier rule.
Studio | Its name for the mechanic | Signature title | Multiplier rule |
NetEnt | Avalanche | Gonzo's Quest | Ladder: 1x, 2x, 3x, 5x in base; 3x, 6x, 9x, 15x in free falls |
Pragmatic Play | Tumble | Gates of Olympus, Sweet Bonanza | Multiplier symbols land, sum applied at end of chain in free spins |
Big Time Gaming | Reaction | Bonanza | Free spins: +1 per reaction, unlimited |
Games Global | Rolling Reels | Immortal Romance | Ladder up to 5x in Michael's free spins |
Thunderkick | Dropping Symbols | Esqueleto Explosivo | Ladder: 1x to 32x per drop |

BGaming | Cascade | Bonanza Billion | Multiplier symbols added together at end of chain |
The naming causes confusion and nothing else. A tumble in Gates of Olympus and an avalanche in Gonzo's Quest are the same removal and refill; what changes is whether the multiplier climbs a fixed ladder, adds up from symbols, or grows without limit.
Gonzo's Quest set the pattern in 2011: each consecutive avalanche moves the multiplier one step up a fixed ladder, 1x, 2x, 3x, 5x in the base game and 3x, 6x, 9x, 15x in Free Falls, and any spin with no win resets it. Esqueleto Explosivo runs the ladder to 32x. The ladder rewards chain length and nothing else: the fourth cascade is worth the same whatever fell during it.
Pragmatic Play's tumble games put multipliers on symbols. In Gates of Olympus a multiplier orb, worth 2x to 500x, can land on any tumble and stays until the chain ends; in free spins every orb's value is added to a running total that applies to every later win in the round. Sweet Bonanza uses candy bombs the same way. The design rewards what lands rather than how long the chain runs, and a single 500x orb in free spins is where the games' largest results come from.
Bonanza and its Megaways relatives count reactions in free spins and add one to the multiplier for each, with no ceiling and no reset until the round ends. Bonanza Billion from BGaming keeps multiplier symbols on screen through a chain and adds them together at the end. Both reward long chains, and both can produce a multiplier that no ladder reaches.
Megaways reels change height every spin, and a cascade on them refills each reel to its current height, so a chain can move across boards of 3,000 ways and 60,000 ways in the same spin. Bonanza, Extra Chilli and Buffalo Rising Megaways all cascade this way, and their unlimited free spin multipliers depend on it. Piggy Riches Megaways and Gonzo's Quest Megaways from Red Tiger bring NetEnt's ladders onto the changing reels. The Cascading Reels lobby lists the Megaways titles on their own shelf because the bankroll they need is set by the multiplier design, not by the engine.

In free spins the same chain would have added 7x to the round's running total instead of applying it once, and every later tumble in the round would have paid at that total or higher. That difference is the whole reason the free spins in orb games are worth waiting for.
Because scatters can arrive on a tumble as well as on the initial drop, a cascading game triggers its bonus in two ways: the scatters land together, or a chain keeps refilling until enough of them have accumulated on screen. Gates of Olympus needs four scatters anywhere for fifteen free spins, and a three-step chain that adds a scatter on each step is a common way to reach them. Bonanza needs four letters spelling G-O-L-D, and its top reel refills with the rest. The practical effect is that a long base-game chain is worth more than its wins: it is also extra chances at the trigger. Cascading Reels notes the trigger count on every game page.
A cascading game pays in bursts within a spin rather than across spins, which changes two things. The first is time: a spin with five cascades takes as long as five ordinary spins, so a hundred-spin session lasts longer and feels busier. The second is variance: because the multiplier rises within the chain, a small share of spins carry most of the return, and the base game between them returns less than its hit rate suggests. Cascading Reels prints a stake floor on each game page: a hundred stakes for ladder games such as Gonzo's Quest, two hundred for symbol-multiplier games such as Gates of Olympus, and five hundred for the counter games such as Bonanza.
Every promotion at Cascading Reels shows its wagering requirement, game weighting and stake cap while the bonus is active. Cascading games count in full toward wagering unless the offer says otherwise. A free spin round in Gates of Olympus can move a bonus balance a long way in seconds, and a stake above the cap voids the bonus, so the cap is the line to read first. Free spin awards are tied to a named game at a fixed stake. Cashback, where offered, is calculated on net losses over the stated period with its own terms alongside.
Balances are in EUR. Deposits by Visa, Mastercard, Skrill, Neteller, Trustly and paysafecard are credited on confirmation. Withdrawals return to cards, e-wallets or bank transfer after identity and address verification; e-wallets are released first, and paysafecard cannot receive payouts. A document uploaded at sign-up keeps the first withdrawal from being held for checks.
The lobby runs in a phone browser without an app; six-by-five and square grids fit portrait screens with the multiplier total above them. Stake controls sit behind a menu icon, so confirm the stake before the first tumble. Deposit limits, loss limits, session reminders, time-outs and self-exclusion are in account settings, with lower limits taking effect at once. Cascades make time pass quickly; a session reminder is the tool for that.

The help centre at Cascading Reels explains each studio's multiplier rule in its own words, with the paytable line quoted, and covers verification, withdrawals, limits and bonus terms on separate pages. The support team is reached by chat or contact form from the account menu; account matters are handled only with the verified holder.
