Slots with unlimited cascade - while you win
Definition and spin cycle
An unlimited cascade is a cycle of "win → delete symbols → drop new → revaluation," which is repeated until the first empty step in one bet.
Algorithm:
The cascade is not formally limited by the number of repetitions (limits only randomness and field geometry).
Where do you meet "while you win"
1. Line/ways slots with cascade (Avalanche/Rolling/Cascading Reels): payouts on lines or on adjacent reels, then "collapse."
2. Megaways + Reactions: variable drum height (up to tens of thousands of ways), top track, reactions to "empty" step.
3. Scatter pays 6 × 5 (Tumble): pays for the number of characters in the field (8 +), then Tumble, the cycle repeats.
4. Grid grids (5 × 5, 7 × 7) with clusters: pays cluster 5 + orthogonal; delete → drop → repeat.
Multiplier options with unlimited cascade
Without multiplier: the series itself gives the total gain.
Stepped factors per series (for example, ×1→×2→×3→×5 in the base): grow inside one spin, after completion they are reset.
Unlimited progress multiplier in the bonus (typical for Megaways): + 1 for each reaction, not reset until the end of the freespins. Source of "heavy tails."
Cell multipliers in grids: Each cascading "scroll" swings the cells, boosting future payoffs in those coordinates.
Wild with factors/moving multi (grid/cluster): moving, they add/transfer × and pull the series.
How to recognize an unlimited cascade in rules
Look for Cascading/Tumble/Avalanche/Reactions continue until no more wins, wins are evaluated again, symbols are removed and new symbols fall from above.
Additionally for Megaways - mention of top reel/horizontal tape and "number of ways changes on every spin."
Impact on math and sensation
Hit rate bases are usually higher (there are often small chains).
Volatility is generally higher than that of non-rolling drums: one successful series is able to "stretch" the result of the spin many times over.
With an unlimited multiplier in the bonus (Megaways), the variance becomes very high: a significant proportion of EVs are concentrated in rare long series.
In grids 7 × 7, unlimited cascades + modifiers (deletion of classes, giant-Wild 3 × 3 with division, moving mults) → long "breakthroughs."
Synergies that strengthen "while you win"
Top track (Megaways): adds symbols/wild to the center - increases the chance of prolongation of the series.
Destructible blocks (Temple/TNT/Cluster Tumble): each reaction "clears" the field → the next reaction is more likely.
Mystery symbols and transformations: convert the "almost cluster" into a payment one, extending the cycle.
Sticky/persistent Wild: stay on the field and "stitch" the series within one spin/freespin.
Examples of titles with unlimited cascade (landmarks)
Megaways/BTG: Bonanza, Extra Chilli, Millionaire Megaways - Reactions "to the first blank," unlimited multipliers in free backs.
Tumble/Scatter pays 6 × 5 (Pragmatic): Sweet Bonanza, Gates/Starlight - Tumble to "empty," bombs/global multi in bonus.
Grid (Play’n GO/Relax): Reactoonz, Moon Princess, Rise of Olympus; Relax - Temple Tumble/Cluster Tumble/TNT Tumble (series unlock field/modifiers).
Avalanche (NetEnt): Gonzo's Quest - cascade to the "empty" step (multi steps in the base/bonus).

Common mistakes
Waiting for a "quick" bonus due to frequent mini-series in the database. Real EV - in long series and/or bonus.
Ignore effective bet with Ante Bet. Consumption is growing by 25%, not "a little bit."
Dogon after "almost" series. The series in the next back is independent.
Buy bonus without limit. An unlimited cascade in the bonus does not guarantee a strong outcome; keep a fixed plan.
Result
"Unlimited Cascade Slots" are games where reactions go all the way to the first blank step, creating frequent micro-events in the base and a high ceiling in bonuses. A bunch of cascades with track, modifiers and multipliers forms high volatility and "heavy tails" of results. The practice for an AU player is simple: check the RTP version, understand the mechanics of a particular title, count the effective bet, plan 200-400 + bets per session and fix the limits - then "while you win" will work for you, not against bankroll.
An unlimited cascade is a cycle of "win → delete symbols → drop new → revaluation," which is repeated until the first empty step in one bet.
Algorithm:
- 1. Calculate all winning combinations of the current field state.
- 2. Calculate the payment, delete the characters involved.
- 3. Fill voids (gravity from above, from a side track or according to grid rules).
- 4. Check for new matches. If so, return to step 1; if not, spin is complete.

Practice for Australian players
Pre-Game Check:
- RTP version for a specific operator (one title - several presets).
- Availability of Ante Bet/Buy Feature and their working conditions (effective rate, purchase price).
Bankroll (landmarks):
- Tumble/grid 5 × 5: 200-300 base rates per session.
- Megaways/Grid 7 × 7 with aggressive modifiers: 300-400 + bets.
- With Ante Bet (+ 25%), recalculate the budget at an effective rate.
- When Buying Feature - record the number of purchases (for example, 3-5) and stop loss.
Pace and reading of the field:
- Megaways: Watch the top track and the openness of the middle drums - they are the ones that hold the series.
- Scatter pays 6 × 5: evaluate the "viability" of the screen (how many potential repetitions after Tumble).
- Grid: look for precritical shapes (almost 2 × 2, Wild "bridges," cut/transform lines) - do not accelerate auto-spin while reading the grid.
